Hi all
I must say that I have always had the smell of fuel around the car after filling up but on my first outing this year with the club, the smell of fuel was overpowering.
Once I got the car home I investigated the boot (trunk) and found that the carpet was drenched in fuel. Then I noticed the difference in fuel pipe sizes - filler pipe and spigot from the fuel tank (after 13 years - doh!) Stripping this down I discovered that the tank was aluminium and looked to be home made and that two rubber connectors had been used one over the other to effect the connection to the tank. OK, the solution - modify the filler pipe to suit - this was done along with a new section of rubber hose. Next fill up - the same problem - true cause must be the sender seal, undid the screws - sorry I mean Self Tappers! to reveal a rubber gasket. Now I am not sure if the gasket should be rubber or cork, but trying to tighten the self tappers on the rubber proved difficult as the rubber was squeezing out of the joint and one of the screws appeared not to be effectively tightening. Solution - built myself a clamping ring using a large fabricated aluminium washer from 3mm plate and fitted it with six rivnuts or rivet nuts. I then cut the ring in half to install it on the inside of the tank. Using the existing ST holes and M4 screws, I fixed the two halves inside the tank and drilled through the tank and the ring once each side and using some M3 countersunk nuts and bolts fixed the two halves of the clamping ring to the tank. I then removed the six M4 screws and fitted the rubber gasket and the sender back into position, the rubber seal still squashed out but I have now made a cork seal to replace it should the problem manifest itself again. I suppose that I had better get a proper tank in the fullness of time, along with a new filler pipe and sender as the existing sender looked as if it had been modified somewhere along the way and not very well either.
