Working on finishing my fuel system this weekend. Im running a fuel cell and I already got the old tank out and everything. Im looking at the fuel line shtta go to the front but im confused. Theres the three lines, i know the thick one if for fuel delivery and the thinner one is for fuel return but then theres a third one. I remmeber unhooking it from the fuel pump a fe months ago but whats the third line for? can I just plug it up or what? I can post a pic if needed, lmk

Thanks Guys

 

Pretty sure it goes to the charcoal canister where the gas fumes are stored. The fumes are then burnt when you are driving down the road.

I plugged mine off to removed the canister from the engine bay to clean things up. Had to install a vented gas cap also.

 

Alright if thats the case then ill plug it up since i pulled all that junk out

 

One more question. I bought a used external fuel pump from a guy on these forums. Do I need to prime it a bit b4 I try runnig it or what?

 

Typically not.

 

Cool, thanks for the quick response also, wanna get this done!

 

I would mount the pump so it is below the tank as much as possible(gravity fed) and install a filter between the tank and the pump so you don't damage the pump.

 

Hum got the filter in that spot but the pump is about 4 inches higher than the cell
