Fuel Line Size (Page 1/1) imacflier JUN 05, 06:49 PM Good Evening, All, Simple question: I need to pump out my fuel tank (stale fuel). What is the size of the fuel line leading into the fuel filter (so I can buy the right sized fuel hose)) Tia, Larry Gall757 JUN 06, 10:54 PM turns out the answer is not so simple. I see lots of information when searching, but nothing about the line at the fuel filter. imacflier JUN 07, 10:22 AM Gall757 If it were easy to find, I would not have asked! Thank you so much for trying, though. Mebbe, some kind soul who has their car up on jackstands could throw a caliper on the line??? PLEASE? TIA, Larry Honest Don JUN 07, 10:56 AM Feed uses 3/8” hose Return uses 5/16” imacflier JUN 07, 02:05 PM Honest Don, Thank you so very, very much!! And thanks to all who tried to help! Larry
