I tried to search but couldnt find anything. I drop the tank out and didnt mark the lines to the tank. Witch one goes where.

 

the 1/4" line on the front (lower line) is the return, the 5/16" line right above is the feed, the 1/4" on the very top is the charcoal canister/vent


*this is assuming the tank in question is a 12a equipped cars tank
