hatchsub Posted June 19, 2008 Share Posted June 19, 2008 Not sure what its for but i know you dont need it. There is no hookup for it with a weber. Just unplug it at the firewall and cap it. Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted June 22, 2008 Share Posted June 22, 2008 There's 3 lines from the tank - fuel supply, fuel return, and vent. None of them should be capped off. The vent and the return can be left open if you wish. GD Quote Link to comment Share on other sites More sharing options...
Yo'J Posted June 23, 2008 Share Posted June 23, 2008 Doesn't one go to the heater assy. and one to the brake booster? Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted June 24, 2008 Share Posted June 24, 2008 Doesn't one go to the heater assy. and one to the brake booster? Yes..... but we were talking about tank lines - not vacuum lines. Tank lines are for fuel or fuel vapor - not manifold vacuum. GD Quote Link to comment Share on other sites More sharing options...
