Fuel leak

Postby scotttie » 08 Jul 2019, 19:25

Hi all,

Today I walked past my van and got an alarmingly strong whiff of petrol... Got underneath and found a massive puddle of petrol! glad I caught it before anything bad happened. So it's leaking from where the fuel filler meets the tank. I've drained the petrol to below the fuel filler neck seal to stop it leaking. Question is, is this a gearbox out job? Looking at how awkward it would be to get to I'm guessing yes? Gearbox is coming out in a couple of months so it can get sorted then, but I was just wondering I can fix the leak before then or not.

Thanks as always!
Scott

If its rotten filler pipe or perished seal where it goes into the tank these are straight forward enough to replace with out much grief.
Be prepared for rot on the inner arch behind the filler tube.

Favourite area for rot because its a mud trap. You'll have to remove the damper and the pipe has to be pushed into the tank a little way to disconnect the big fuel hose in the D post conduit, before rotating and swearing it out.
It can try the patience.

Thanks for the replies Ian and Bigjcc55.

Ian, sorry if it's obvious but what's the damper? OK so if I understand right the pipe is just pushed into the rubber seal on the fuel tank? So once I manage to get the pipe out is it a case of getting the old seal out and putting a new one in? I had a look on brickwerks for a replacement seal but couldn't see one.

Fingers crossed there isn't much corrosion but one thing at a time!

damper is also known as the shock absorber, not really the correct term for it, it's function is to damp the action of the suspension hence damper

chances are it's the steel pipe that is perforated, pin hole on the back usually

Thanks for clarifying Aidan. After having another look it was obvious that the damper/shock would have to be removed to have any luck getting the filler pipe out. I'm going to have a go at getting the pipe out and see whether it has any holes in it. If not I'll swap out the seal. Is it recommended to use some form of sealant when installing a new seal?
