Hi, with ref. to my 1984 k100, one thing thats been on my mind is that of the wiring of the fuel pump in the tank covered in fuel?? do they ever blow up.

Never heard of it happening and may cars use a similar arrangement. You need an arc short aross a gap, like a spark plug, in fuel vapour, to get a big bang. So always disconnect battery and power off when working in tank....even if you pull the tank plug connector.

That's why you should always wear ear plugs.

I have never heard of it happening. To ignite petrol in liquid form is almost impossible and even the vapour needs to have the air vapour mix right to ignite. I think these figures are right but I will stand corrected. If the mix is less than about 3 to 1 or over 18 to 1 then it wont ignite. That's why a lean mix wont ignite in an engine and a flooded engine wont start. Usually the pump and gauge are below the fuel level and also the air to vapour mix above the fuel level is like a flooded engine.
Almost since the advent of electric fuel gauges there has been 12v connections inside the tank and those senders would be far more likely to develop a fault where arcing would occur than a fuel pump.

I think the worst that could happen is if you had a leaking fuel line and fuel got onto a hot engine. That might set your pants on fire affraid

I think if I was the guy second from the right, I'd be moving off pretty quick.
