Pollack Valve with carb to EFI conversion

[Doppleganger]

Installing new lines - going from carb to PF4 system. I noticed what would be the 'return' 5/16 line on the old Pollack, goes to a plastic T and dead ended (I believe) at the canister. Looks like the original vent line was through the Pollack, which I thought odd.

This cant be right - was wondering what the 'new' FI way of plumbing the 1/4, 5/16 and 3/8 is.

Thx.

Thats how I initially drew it up but the original (which I have intact) was the way I described. Not saying it was 100% nuts as it was carb and this is EFI.

So, as they HAD it plumbed, I'm going to swap the return and vent line positions.....take the 1/4" vent to a T and run it up to the canister.

?!

Thx.
