Does anyone know whether I can get fuel resistant sealant as I would like to run a bead of sealant round the pipe that connects from the filler cap to the neck of the tank as sometimes you get a very slight leak now and again.

Sikaflex or equivalent - most polyurethanes are fine in my experience.

Glued my fuel sender on with the Everseal stuff and no problems.

Pat...

Cannot remember the grade you require (IIRC it begins with PRC... something like 1121a, but it was 15 years ago) but these people do a 2-pack compound I used to use on aircraft fuel tanks, smells liek s*** and sticks like it too! Doesn't degrade - be aware it is a mega-adhesive, it is a b****** to get off.

If you are not sure about a particular sealant - run a length out, let it cure and leave it in some petrol for a while. You will soon find out if it gets eaten up or breaks down.

You shouldnt have too many problem with filler pipe if it is a close fit to the tank inlet and you use a good quality clamp nice and tight. Mine hasnt leaked.

The pipe is the corregated type from MAC1, I have two clamps on it and it still leaks very slightly when you fill the tank, the reason you cannot get a perfect seal is because the tubing has wire running through it so it can't clamp perfectly to the filler neck.

Ive got the same one and havent noticed a leak - maybe i need to takle a closer look. The pipe was very tight to squeeze over the tank inlet, i wonder if that made a difference.

TBH you wouldn't notice it normally but after filling the tank then run your hand down the sidefront of the tank (from underneath) and you may find a small amount of fuel or a slight sticky residue left over from when you last filled it.

I am also aware of another builder where it was noticed at SVA but he passed it off as where he'd been cleaning stuff.

Loctite 518 is a great all round purpose sealant that I have found oil and fuel resistant. It is quite expensive but does not go of in the tube so will last years.
