Doesn't the vent line need to be connected to a kind of charcoalcanister ??

I think if I go EFI that I will make a metal line all the way back to the tank. I know NHRA doesn't like you to use very much rubber line in the fuel system, probably for this reason.On FiTech face book group somebody posted there vent line cracked and sprayed on headers...he lost his truck
I didn't think the vent line had that much fuel going through it. Scary thought.On FiTech face book group somebody posted there vent line cracked and sprayed on headers...he lost his truck
Larry, are you talking about a return or a vent line? Big difference obviously.I have mine vented into the filler neck. Have found after shutting off and sitting for 10 mins or so opening gas cap and seeing fuel spitting out into the filler neck
I wanted to make this clear for anyone who might come along and find this thread and use it for info on their own project. There are two different set-ups with the FiTech units. Mine is not using the Fuel Command Center (FCC) but rather a return system with an in-tank electric pump set-up. Yours, like a couple others here used the FCC thingy so you could use the "normal" mechanical or carb style (pressure) inline electric pump. You are talking about the vent line from the FCC. My thread here is about a tank vent set-up, different animal but similar in function. With my set-up there is both a fuel feed line and a return line along with the tank vent. Both set-ups require venting but given the comparative pressures, purposes, etc. both vent requirements/functions are quite different. In your set-up, it is dealing with typically just 5-7 psi and in mine the pressure is much higher (feed is regulated at 58 psi) and there is constant fuel return creating fuel to air volume displacement in the tank that has to be accommodated.It's called a vent line, but if the temp in the Command Center rises it will spit fuel out.
It can also be an overflow line if the needle and seat sit in the CC.
It's not a return line as such but at times it could be
