Fuel tank in. All nicely lined up.
Which side of the handbrake cable does the fuel tank vent pipe sit? Forward or behind? Does the pipe attach anywhere either to the body or chassis?
Thanks
Jim

Sorry, I forget the model of your car (project). I think the vet is the same on all models though.

It attaches to the fitting on the top right of the tank and drops straight down through the floor and protrudes about 2 - 3 inches. All that locates it is the tank fitting at the top and a grommet at the floor. The grommet dictates where it passes through the floor.

It is a steel pipe with a upward half loop at the top to help stop fuel running out but is not that successful, see Rob Bradford's article on this in the Tech section.

If you put a sealer kit through it then check that the vent is still open. The vent runs across the top of the tank(inside it) to the left side and sealer can get in this pipe and block it. Always blow through the vent when applying sealer to ensure this does not happen.

It is a bugger of a job to unblock it, I know from bitter experience.

Thank you for all your help. Yes mine does extend to the bottom of the chassis rail and there is a hole for a clip. Crawling underneath I obviously didn't shine the torch in the right place initially.
Now after Aladdin's comment I have to go and check that it actually works.
Cheers
Jim

A simple check valve in the connection between the tank and the vent pipe effectively eliminates petrol sloshing out.
Well worth the effort. The beads might cost $2.50 tho.

I also checked my pipe as petrol smell was coming from the car all the time . Also stunk out my garage too. I found it wasn't going through the grommet as the pipe had been pushed up. So I pushed it back down so it protruded 15mm then fitted a rubber fuel hose over it. On the other end of the hose I fitted a gravity non return valve which allows air in but not out. I also fitted a weak pressure relief valve to stop pressure building up on a hot day. Works great so far. Reduced the petrol smells by 90% so very happy.
