Hi, i have a leak on my 1979 type 2 van coming from the 90° knuckle which the fuel hose connects to. The front of it has fallen off due to rust and the rest of it isnt too flash hence why its leaking. Is there anything i can do to fix this with tank in situ? How thick is the tank? I was thinking i could remove the rest of the rusty hose connector and drill and tap new hole in the tank and screw in a hose connector? Ive tried cleaning up the remainder of the knuckle but it still leaks, badly! Ive also put new fuel pipe throughout so its not the fuel pipe leaking. Many thanks.

I would look to get a new tank if it were me. You are proposing an in situ bodge which sounds risky with fuel and fuel vapour around.
Ive just noticed you can buy a fuel tank outlet replacement kit. Not quite sure how it fits on the tank when its in situ though
That's for earlier tanks. Later tanks had a brazed pipe. Sounds like yours has rotted around the connection. New/used tank time, I'm afraid.
Deffo new tank ...don't bother going for second hand , there will usually be some thing not quite right . If you have the money treat yourself . One big advantage is you will never get any crud foiling your filter and any part of your fuel system for a long while
I would cut the end off to see if there is any good metal nearer the tank... if it is on the road i would be tempted to put some jb weld on the risty bit and push the pipe on and tighten ,if it was a resto I would weld it...
I soldered a new pipe on, but I did have the tank out, and I purged it some considerable time before I applied the heat. Whatever you do you'll probably have to pull the tank out.
The rotten outlet pipe has told you its time for a new tank. You don't want to mess about bodging the fuel system, it will let you down or worse. Good opportunity to replace the tank with a nice clean rust free one so no more cruddy bits to hit the carb. With the engine out and tank out, good time to replace anything else that needs doing like breather pipes, filler hose etc. as well as painting up the engine bay, that's what I did. You know its all done then.
A company has found me a tank but its from a 68-72 camper. He told me it will fit but with a couple of mod coms. Does anyone know the difference between the two?
Hi. Which means what? Do i have to seal them and cut new ones? I havn't the foggiest. I can remove the tank and fit a new one but no idea what i have to do to make this tank work in my van.
You can buy brand new ones from VW heritage, they fit and have the correct vent pipes etc, you just need to make a cut out for the tank drain, I've fitted a few.
Hi. Im having to replace my fuel tank in my 1979 bay and have got to the tank and undone everything... except the two steel straps which hold the tank in place. Done some research on the net and other vans have a worm screw that you use to tighten or untighten these steel strips. Mine has nothing! Just these two steel straps pulled tight over the tank. Only way to remove it is to cut the straps! Then of course i wont be able to use them to tighten back up when i replace it. Has anyone any ideas? I wouldnt of thought so as cutting them is the only way to remove the tank. Cheers Nick
On mine there was a pair of nuts you get to from underneath. You need a long nosed 13 mm socket I seem to remember. Good luck - it was fiddly.
