Does your floor pan have the cutout for the fuel separator?

I ask because once you go to EFI, and you want (and should) to use the EFI tank with in-tank pump, you will be limited to 2 vents on the tank, and one would be needed for a vent/separator return.

What I do is use the 2 vent tubes on the right of the standpipe for vent/return, and let it vent to atmosphere. There's no to little smell this way, and if you wanted to, you could even route one to the charcoal can.

It works good.

If the cap came off the one capped vent on the tank the way you had it, that means psi built up, and you may not have sufficient venting. Just a thought.

EDIT: The EFI tanks technically have a return which enters via the pump assembly to tank fitting. There are 2, small vents on the tank itself.
