Car -ae86

motor -ae101 4agze

use -track/daily

problem -which fuel line is the return?

there are two Fuel lines in the bay, one comes from the fuel tank to the firewall and the other comes from the tank, into the engine bay, loops around and then up to the firewall, which one is which?

sorry for the crappy picture.


any info greatly appreciated.

the smaller diametre one is return, which should be the one sitting on the firewall

not 100% sure on this, maybe someone can correct me. there should be 3 fuel lines from your fuel tank that lead to the engine bay: fuel feed, fuel return, breather line. the fuel feed and fuel return lines are the same thickness, whereas the breather line is slightly narrower. so if you've already located and sorted your fuel feed line, just use the thicker line as the fuel return line, thats how i did my ae86 fuel setup. from the picture, the breather line is on the left side of the engine bay, next to the washer bottle. the fuel return should be somewhere near the brake booster/clutch master. hope this helps dude

edit: looks like shift rook beat me to it

fuel feed is sorted , but wasnt sure on which one of the others were the return, and use are both saying different lines haha?

[shift_rook]

crawl under your car and check! hah, i could be wrong, but i was pretty sure smaller diam is return...

[86TRD]

haha thats what i done, can only see the lines coming from the top of the tank so followed then to the front, so its either the smaller diametre line or the thicker.

[shift_rook]

the 4mm line is the return and the feed and breather are 6mm. The one that runs along the sub-frame and sticks forward is for the breather
