Not really a 'How to' but a couple of reference photos from inside the fuel tank I took when I changed the fuel filter today. Might come in useful to someone going in there for the first time. This is a 16 valve tank, but think it is much the same as other K's?

Looking towards the rear of the tank, fuel filter on the right

Looking forward, fuel filter bottom left and fuel pump top left

I thought I would go refuelling when I started to hear some noise from inside the fuel tank.

It was my fuel pump. Still working put fallen from it's place. Started to look what the hell was going on. Lets just say that I don't think that the po did a good job with the tank. Seal pieces inside etc. broken O-ring some screws (!) holding the pump etc.

I took it all apart, drained the tank and here is what I found.

(That rubber thing looked different in Haynes manual...)

Photos from inside the fuel tank Pp210
(Other part was just lying bottom of tank)

Photos from inside the fuel tank Pp310
(Nice job with the screws man..)

So I think I know now why my bike did not work that well - I actually wonder how it could ever work at all. And after the pump fell off it's place bike worked better (!) with low fuel amounts.

That's a real 'bodge'!

I guess the good news is that the pump is working so should all be fixable?

I removed my original fuel pump (low pressure) to install an after market replacement $17 (Ebay search NEW CARQUEST AIRTEX FUEL PUMP E2024 FORD from seller e-Herko)

I was curious as to what under the pump housing support looked like, so I grabbed my trusty magnetic wand light (u need this in your life) and what I found is shocking! 1/2 thick cake of petrified baby $%@!

Photos from inside the fuel tank Null-1

I removed the tank, fuel filter, taped all the fuel lines closed, drained the fuel, and scratched off the $%@! brick from the bottom of the tank with a spoon. Then light grade steel wool scrub down for finishing touches.

I then washed it out upside down with a hose (All internal parts removed except electrical, fuel lines taped closed) and used a leaf blower to dry it out really well. Ghetto methods maybe....but worked very well and was easy.

My K100 only has 49k miles on it so u guys with 100k + may have quite the "Cleveland Steamer" build up under your pump. Thought I'd pass along the hidden potential pump clogging culprit area...

ALL CLEAN AND READY TO RECEIVE THE NEW PUMP!

If the new pump fixes my woes (Lack of power) I will dissect and attempt to rebuild the Bosch one

All that stuff you cleaned out, is dissolved rubber from the insulator and maybe part of the fuel hoses.
I'm betting that the fuel pump pressure might be ok with a new insulator, a clean tank and a new strainer basket. + a new filter & hoses of course..
I might have been tempted to re test the old pump in a clean environment before condemning it. It could however be still bad. The pressure relief "pop off valve" is a spring loaded rubber thingy in the bottom of the pump....it could be blocked partially open and leaking by debris.
Finally, one has to realize that pressure is created only by restriction somewhere down the line from the pump.......in this case the fuel pressure regulator behind the throttle body assys. in the return line from the fuel rail back to the tank.
When testing for max fuel pressure, one needs to momentarily close (pinch) off the return line below it's return connection back in to the tank ....to see how high the pressure will climb.
Also, performing this test causes the afore mentioned pressure relief valve in the bottom of pump to fully open flowing fuel, that might just "wash it out" a piece of debris that could be blocking it open. A long shot, but worth a try.

So should there be something on that hole where the threads are?

Photos from inside the fuel tank PP1

It was like that when I took it out of the tank.

And then there is a place for a hose in that pumpfilter ( http://kotisivu.dnainternet.net/ajk73/PP2.jpg ) but there was no hose in it. Should there be one?

OOPS....
This is true that the pressure is created by restriction, but....
The main restriction is done at the pressure regulator on the pump (pressure relief valve #1).
The pump generates 65PSI pressure, and then the pressure regulator behind the throttle body assy drops it down to the usable 36PSI.

Photos from inside the fuel tank Fuel%20pump

Here is a simple explanation on how a pressure relief valve is working:
The small hole in the pressure chamber (#2) communicate with the seat of the valve. When the pressure is high enough to overcome the spring pressure, the ball is lifted from the seat and the pressure is relieved by allowing the pressurised fuel to flow back to the tank. At that time, there is no or little restriction, the pressure drops down near to zero and the valve closes and starts to rebuild pressure again.
This is a really quick action and this is why the valve on the return line in the tank (first generation of K100) has the tendency to rattle.

If you have very small particles of contaminant lodged between the ball and the seat (most of the time rubber), a leak is created and the pump may not be able to build enough fuel pressure to overcome the spring pressure, the contaminant will stay pinched between the ball and the seat for ever.
The only option is to dismantle the pump and blow the hole at 80 or 100psi.

I agree completely, but......My point was that you need the restriction at the regulator in order to have ANY pressure in the fuel rail. If the regulator were leaking through the pressure would be very low or none.
The relief valve in the pump only lifts if the fuel system is so restricted (unusual) that the pressure in the system reaches the Max spec.
Your explanation about the possible debris in the pressure relief valve was exactly my point......that if the owner restricts the fuel passage at the return line, that it may cause the relief valve to lift enough, hence washing it out. Worth a try, IMO. He has to pinch off the return line to test the max pressure anyway.
A fuel pump flowing without the benefit of the pressure regulator would produce no pressure in spite of the pressure relief valve feature. Conversely, an open pressure relief valve would produce no pressure in spite of an operable regulator.
Either part could cause the pressure to leak out

While I wait for my Clymer's manual to arrive I turn to the forum experts. I'm having hesitation issuses with my '91 K100rs. In different gears I get some jerking from the bike, under acceleration it seems to be fine. But it will do it at constant speed and when slowing down. In addition to the hesitation, my bike is also stalling when coming to a stop with the clutch in. I don't know if it is starved for fuel, or air, or if its an idle adjustment...could a bad fuel pump cause these symptoms?

You probably can download a manual from someone here, I'm note sure, you may have to meet some requirements before you can download it. Factory manual in many cases will be better than Clymer.
You description of symptom could lead in may directions. Given the statement that appears that sometimes on accel the bike is strong, it's probably not a faulty fuel pump. Lots of reading for you to do here.
Likely you have an intermittent elect connection. You need to unplug and reconnect solidly the Fuel injection computer plug under the tool tray. Locate the connector that takes power into the bottom of the fuel tank. pull & reinstall that.
Search for reference to "Deoxit" in the forum & buy some.
Remove the fuel tank, disconnect/clean/deoxit the brown wire ground connections attached in a stack on the left side of the frame backbone.
Disconnect deoxit and reconnect the main connector to the IGN switch and to the right handlebar switches assy.
That will be enough to get you in the right direction. You'll get other great suggestions here.
We all have a good "Guess" however.....the key is to learn good diagnostic practices and use them.
Lots of info in this forum, all you'll ever need.
Start at the home page article "So you just got a K100, now what"
Regards, ibj...

Sounds like the TPS to me . The Throttle Position Sensor is not like the 8v Ks and if you move it slightly counter clockwise (looking from the back of the bike) about 1mm at a time then go for a ride and try it.
The TPS on a 16v has a variable resistance through the range and if it has been moved then it will run lean or rich depending on which way and yours sounds just like the problem I was having at one stage.

Stupid question. One of my many.

Should there be 2 hoses under the tank? There are two places for hoses. Somekind of overflow system I think. Allready bought hoses, but tought I ask before I put them.

Yes.

One is the tank overflow and the second one come from the gas cap (Drain hole for water).

On the K1100 a small plastic recipient is clipped to the frame and the overflow drips in.
In this case, the two hoses are attached to the recipient (nothing is attached to the tank)
This recipient works on K100 too, and if you can find one, this is a better option.
The big advantage is that you don't have to remove the hoses to lift the tank.

Photos from inside the fuel tank Drain10

Just for information, I am using the overflow hose to transfer gas from the auxiliary tank in the sidecar to the main tank on the bike.
The fuel pump in the sidecar doesn't build any pressure. just flow, and it may take 10 min. to refill the tank. The refill can be done when riding. (No need to stop at the gas station)
If the bike's tank is too full, it drains into the auxiliary one.

You DON'T plug it.
You have to install a hose going down toward the ground (Usually on the back of the swing arm).
If you plug the overflow and overfill your tank the gas won't have any other way to escape than going all over the tank by the gas cap.

If you don't install a hose (or the K11 small plastic recipient with a hose going toward the ground), when you overfill your tank, the gas will go on the engine and the electrical loom.
(good chances to start a fire).

By the way, the two hoses that I am taking about are on the right side under the tank. They are the pain to install or remove when you want to take the tank off the bike. The K11 solution is more efficient. the plastic recipient which is a funnel stays on the frame.

My 85rs has one tube going straight down into the plastic Air tray. The air tray has a tube leading rearward.

The other tube has a 90 degree rearward turn and also has a hose to send the drain water down to the road.
The straight down tube sits in the air tray, the 90 degree pipe sits outboard of the tray. This is not however the original tank. Seems there is several different configurations of these?
Although the fuel tank is pitifully small on my rs compared to other bikes, It still goes a minimum of 175 miles between stops which is about 75 miles further than my old butt can go without getting off for a short walk, so I can't imagine needing the aux. tank. I suppose the chair rig uses substantially more fuel and may justify carrying more on board. I wonder if that heavily "optioned rig " also has a potty on board?

Yes the chair uses more fuel, but having weight on it makes it more stable (I am not comfortable anymore riding with the chair's wheel in the air. This was great when I was younger).
I believe that if I am riding at speed limit, I could go at least 500 miles when both tanks are full.
For the potty, just open the hatch on the floor. Great when somebody follows you to close. Photos from inside the fuel tank 44271

That looks like a good way to route the hoses. I asked because I did order two hoses, but I was unsure if I needed to install them. My K also came with no hoses when I bought it.
Btw, Tenox, I like your colour scheme and the cut footrest brackets!

This is the way that they are originally routed.
The hoses don't have to be the high pressure one as there is no pressure at all. They are originally smaller.

I think one of the clips may be bigger than the other but don't quote me.
I have found putting the clip closest to the front of the tank in first and then pull the pump towards the back of the tank to seat the second clip.
Hope that helps and makes sense.

Art, have you noticed that the tabs on either side of the pump holder are different widths?
It will only go in one way. Try turning the pump holder around through 180 degrees.
Also, make sure that the fuel pick up is at its lowest point when in place or it can make a difference to how much reserve you think you have after the light comes on.
If you already know all this, keep fiddling with it. You'll get there.

So while we are here, after changing my filter and hoses on the weekend i found this.
My pump has the screen in the base.
is this a bodge job or a ligit filter?

This pump is not the original, and I think that it has been cut down. It has the filter built into its interior. This type of pump Romeo used Peugeot, Alpha, if you can see the previous listing what's in the link that I put in the previous post, you will see the different models of cars that used bombs similar to the one of our K

RossKo that is the early type of prefilter before it was changed to the basket with a hose to the top of the tank apparently to prevent cavitation in the pump.

The first filter was exactly like the latter one but for the hose connection. It is seated over the rubber vibration damper lower part, however that rubber part has a difficulty with modern fuels and expands or even dissolves. Difficulty is that when the rubber bit is expanded it is difficult to fit the filter over the bottom part and very difficult to fit the pump in the holder.  If you find that's the case think about getting a new one as it is on its way out.
