The only one I've ever had to replace was one that someone else had punched a hole in (ON PURPOSE!!!) > When I was siphoning fuel out from where the sender hole is, I could > clearly see a gush of fuel coming out the hole in the bottom of the tank > into the bowl. So, that opening is clearly fine. FYI, it's more than just a hole. It's actually a kind of pump. The returning gas comes straight up the pipe, but it drags some of the gas from the main part of the tank in along with it so that the center cup will fill to a higher level than the main tank. In use, the center tank will stay completely full until the main tank is completely empty. This has the advantage of giving you access to every bit of gas in the tank, but also the disadvantage that once the tank is empty it's REALLY empty. > Frankly, I couldn't do better with an NOS tank.

Since there are so many other places that are more likely to leak gas, my guess is that even his old tank was fine. In general, I think the only tanks that really need to be replaced are those which sat open in the rain for 5-15 years. -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
