Gas tank outlet - options

The existing problem with my gas tank is that the distance between the outlet threads and the top of the transmission is no more than 1/4". This means that the standard petcock/ outlet won't work as there isn't enough room.
1) I can pull the tank, grab a hammer and pound the threaded outlet into a better position where the stock petcock would fit.
2) I can do the same thing as 1 but add a #6an adapter to it for a more "universal" option with the fuel system. (this part)
3) The last option is to either relocate (weld in) a new outlet in a better, more accessible, low section of the tank. This could either be the same M18x1.0 or a #6an bung.

The tank is a high quality thicker metal aftermarket tank (not aluminum) so welding isn't an issue.

Thoughts, experience?

Since it's a new tank, pull it and do it right. Close up the existing and relocate the hole. Or, add shims under the flange (if it has one) to raise it enough to put a fitting into place. A stock Beetle outlet isn't much more than 1/2" in depth (C31-298-221-113A - CSP - OVERSIZED 8MM GAS TANK OUTLET PIPE/NUT/WASHER KIT - HIGH FLOW - STANDARD BEETLE 62-77 / GHIA 62-74 / TYPE 3 62-67 / THING 73-74) so you should be able to fit something in it's place.


How's that for a definitive answer *laugh* ?

I cannot raise the tank at all as it has mm of clearance if not less already. I think I'm agreeing with you about cutting it amd relocating. Hope there isnt a factory coating.

In my experiance with gas tanks all of the steel ones that I've looked at had some kind of a coating on it. inside and out.

Is it possible that the tank you have is made from stainless steel??

Maybe. You'll always have a little bit of water in the gas just from condensation. You might get lucky and not have the powder coat lift on the inside when you weld. Personally, I'd braze a fitting on - the steel is too thin to weld effectively.

I will look but I can't imagine they were able to coat the inside unless they did it prior to attaching the top and bottom. That being said I will take your advice about the brazing. Thanks Rick.
