so i took out the wrong fuel line on my truck while doing the tpi swap. it had the return line and the feed line to the carb. i took out the old feed line (instead of the return line) can i use the old carb return line(1/4) as the tpi return line? i know most people use their old feed line(5/16) as the return but i'm dumb and took it out. theres only about 3-5lbs of pressure in the return line right. or could i get rid of the canister purge and use its 5/16 line? but if i do that wont the gases build up in the tank ...how do i vent it? or could i even keep the canister purge and swap lines...1/4 goes to canister purge and 5/16 goes to return line. one again..i fubbared.
