Submersible fuel hose in OZ can be dear and hard to get I've been quoted $100.00 a metre for T10. A few years ago I found a local Motorsport shop that stocked T10 and with membership it was $17.00 Au a metre they also stocked stainless EFI hose clips in a pack of 10 or single. One of the K Kronies dad who resides in Canberra was unable to purchase submersible hose and or clips, so I was asked if I could help. I haven't been to their store for over 3 years so I dropped in and asked for a metre of T10 and was asked where it was going to be fitted. I said in tank for fuel injection, so he said there is now something better. Gates Barricade SAE 30 T14 submersible rated to 225 PSI suitable with multiple fuels approved for use with leaded and unleaded petrol, diesel bio diesel B100, E10, E15, E85,  100% Gasahol, Methanol, Ethanol. It came out to $25.00 Au a metre with membership stainless hose clips were $2.50 Au each or $13.00 Au for a pack of 10. It sounds like with the specs it might last a lot longer than the T10.

Thanks for the research, Martin.  A quick search shows that FortNine, an aftermarket parts supplier in Canada, has this hose in stock in two lengths and several I.D. A 2 foot length of 1/4" (6mm) is $28 and 25 feet is $176.

Interesting information on fuel line grades:

Scroll down for some interesting reading on turbochargers.

I can't find a reference to a T14 standard, Martin. I've only come up with T2. Will you post the Gates product number for that Barricade hose? So far, all copy I'm reading about Barricade seems to indicate it isn't submersible.

Laitch I actually queried the supplier Motorsport accessories and they assured me that they get it directly off Gates for submersible applications. I'll go direct to Gates today for a definitive answer. 
Regards Martin.

Here's information from the Gates website concerning Barricade. I've done a two-parter of the page for legibility. Although Gates also manufactures 30R10 submersible, one of Barricade's selling point seems to be elimination of vapor loss, which is not a particular concern for hose that is submerged. I've found a few contradictions in entries on Gates website pages so what you get from them directly would settle the matter.

The query that i sent to Gates.
 
I went to get some submersible EFI T10 hose from my local supplier and was told there was now something better T14. When I got home I couldn’t see any markings on the hose stating submersible, so I rang them. I was told it was rated to 225 PSI and that it was purchased from Gates as submersible EFI hose. I posted  on an online forum that there was now a better hose than the previous T10. I then received a query from the US as to where it was rated as submersible. I would greatly appreciate your help in clarifying this matter.
Regards Martin.


The answer that I received.


Hi Martin,

I have spoke to our Technical Team and the only information they have is as below;

https://www.gates.com/us/en/search.p.4219-000000-000012.html

SUBMERSIBLE FUEL LINE HOSE
If your in-tank applications and fuel systems cause your hoses to be in constant contact with gasoline or other fuel fluids, you need the Gates Submersible Fuel Hose. Most fuel lines are only designed to handle fuel on the interior of the hose, which can be damaged if the exterior is exposed to fuel. Gates Submersible Fuel Line Hose is capable of handling multiple types of gasoline and fuels, including gasoline, alcohol-extended gasoline, ethanols, biodiesel or diesel fuel in fully-immersed, mobile and stationary applications. Engineered for fully submersible use, these hoses are excellent for use on gas tank fuel pumps.

Temperature tolerance range of -40°C to +150°C (-40°F to +302°F).
Comprised of a FKM tube and cover with a synthetic fiber reinforcement.
Exceeds required SAE 30R10 standard.
Working pressure of up to 100 PSI.

I now need to see what the supplier say's.
Regards Martin.

It sounds like the counterman at the distributor got a little confused.  SAE30R10 is still the ticket for inside the tank, but the SAE30R14 looks like it might be a good choice for the external lines.

The counter man conferred with the manager and then when I rang back I talked to the manager. And he assured me that they ordered it especially off Gates for in tank applications. I sent them an Email with a copy of my query to Gates and their answer. I am awaiting their reply. The thing is after the phone confirmation by the manager the hose was mailed off to Canberra.
Regards Martin.

Barricade submerged in fuel is likely to tank within the tank, at least according to the Gates website. Maybe everyone should switch over to Esperanto, or espresso, to limit further confusion while the Canberra field trial runs its course. 

The hose is now with Grumpy  

He going to cut a piece off and stick in a jar but from what I'm reading its not sounding promising 

Will be interested to know what your supplier say 

I'm going to be out of the loop for the next two week attending the OCR with Gary B  so that should give the hose a bit of time to soak  and disintegrate

I finally got an answer off Motorsport accessories as he eventually got an answer off the rep. It is not submersible but is fine for outside the tank. He has apologized and offered to give me a refund, however due the fact that the hose is now in Canberra I declined. I've already sent Alex a metre of SAE30 T10.
Regards Martin.

I have been replacing fuel lines and always keep a stock in my shed.

The fuel line for in tank is marked NBR/NBR meaning submersible. The fuel line for outside the tank is marked NBR/CR. You cannot interchange the uses, in tank fuel line has an issue with UV light and the outside fuel tank line is not ethanol resistant from outside. 

My source was tills.de and they are a very good supplier and I suspect a volume order would be cheap.

You should be aware Honda motorcycles use the exact same size and specification fuel lines and I have been able to buy it over the counter at my local Honda dealer at a very good price as in less than AUD$2 a foot. They also use the same exhaust studs long enough for 16v/K1100 . . . . .

@Olaf

thank you for adding your knowledge and experience

@who it may concern
could this information be added to a database, please?

In the U.S. the SAE spec is SAE30 R10 not T10 

According to my Capt. Midnight Secret Decoder Ring the spec number printed on the hose decodes as follows:

30 is the specification group for fuel, oil, and emission hose.  If the hose you are using for fuel doesn't have a 30 at the start of the identification number you can't use it for fuel, emissions or oil systems

R identifies the section of the specification group.  The number after the R is the particular set of specifications.   These specifications are for things such as construction, permeability, flexibility(bend radius), temperature range and kink resistance.  The R number is what determines where a hose can be used; in the tank, outside the vehicle, or under the hood.  If this number isn't 10, you can't use it in the fuel tank.

T identifies the revision level for the section.  I understand that to mean that whenever a hose manufacturer makes an approved design improvement it can be documented by a new T number.  For example: if a new rubber compound that has a better bend radius is approved, hose made with that compound will get a new T number, but the R number will still be the same.  The T number will mean that particular hose will be more flexible than other hoses in the group.

The T number is useful to an engineer because it lets him see the differences in a group of available hose that meets a particular application.  To the end user the minor differences that the T number represents are almost meaningless and that is why nearly all the hose being sold does not have the T number printed on it.  

Bottom line, SAE30R10 should always be printed on any hose you put in your Brick's fuel tank.

Ah, this might be the reason on Big Block, I used a piece of OEM submersible hose on the external return line, and it 'sweats' a bit, feels slightly sticky, but not quite 'wet'. I'll try an exterior graded piece to see if the issue goes away.
