    You have the verify if the size of the line is appropriate for the return line. If I remember correctly, the vent lines were smaller than what was recommended for an efi return.

    I used the 5/16" vent line as a return line from my fuel pressure regulator on carbureted engine. Seems to work just fine for 14 psi electric pump. Might not be large enough to handle volume from fuel injection pump.

    Is that the line that went to the charcoal canister?

    Yes, the 5/16" vent line went to the charcoal canister originally.
