Im wondering about one of the vacume lines its some sort of fuel related gimmick is it ok to leave it open? it goes to a metal line and Im guessing back to the fuel tank. The other goes to the purge valve do I need this....tell you what how much would it cost to have YOU or TAYLOR just get rid of all this vacume bs...I think it might make the motor run better I want to remove the egr and vacume canister. I have the air pump gone...and the heatshield off the exhaust manifold so the egr pipe is easy to get to... I just don't know how to route all the vacume But I want to end up having only two vacume lines FPR and BRAKE BOOSTER...is that right?
