while trying to fix a brake servo i don't have an unconnected pipe was found, when traced it went to the fuel tank, opposite side to the filter etc. i'm a little worried about a pipe from the fuel tank that prob should go somewhere. i looked in haynes, it's on the pic's but not mentioned, anyone any ideas where it should be connected to? she's a 1980 2l Aircooled in a 1600 van
