Gonna be installing a weber carb but dont know what to do with my fuel line(s). I have 3 lines coming from my gas tank. There were 2 lines T'd into one on the stock carb. Do I just keep it the same or can I just run one line?

inline fuel filter.one is the delivery line , one is the return line from the vapor trap( the big black cylindrical thingy on the passenger side fender well) and one is the overflow line from the stock carb (the Teed one).I guess u can run just the delivery line iif u dont mine gas fume smells emanating from ur engine bay.I run a Weber but I kept the vapor trap and return line-I dont like gas fumes.bj

the way i ran mine......the three coming off of the frame #1 has a vacuum line that runs down towards the ground #2 is the feed that runs to a fuel filter then to the fuel pump #3 the smaller hose runs to the return from the fuel pump. hope this helps

Uhh...ok, I'm lost. In the engine bay pic, the left line went to the vapor canister. The one in the middle and the one on the right was teed into one line that went to the carb. That little round thing doesnt look like an inline fuel filter at all. In the hose pic, the two lines went down and the single line with the T went to the carb. The metal bracket was mounted were the mechanical pump would be. So should I just keep it the same way minus the vapor canister? I think one is supposed to be a return line for fuel injected models?

oh ok you dont have a mechanical pump. yeah just leave the two t'd together and run to the carb. mines mechanical so mine is different.

Anyone got pics of fuel lines to a weber on an automatic with in tank electric pump. Does one of the lines connect to the float bowl overflow on the carb?

those two lines that split into one both go to the carb,i think the return is the left line and the rights the main,i think when theres too much it heads back down.

I plugged the small one (but thinking about hooking it back up to the vent on the carb), the one in the middle went to the carb and the last I also plugged. I hope that helps.

I agree with you. You can still run the car with fuel line insulations. Thank you for this information dude. Keep it up!
