That Ol 720 Posted September 10, 2021 Report Share Posted September 10, 2021 Does anyone know the specs for the fuel lines on a 720?? I am unsure if I have the correct size on mine or not and I am getting new lines today. 1 Quote Link to comment
datzenmike Posted September 10, 2021 Report Share Posted September 10, 2021 I doubt the factory fuel line has been replaced already and you are on the third one. Just measure what you have. Unless crushed or damaged why? 1 Quote Link to comment
captain720 Posted September 10, 2021 Report Share Posted September 10, 2021 He's got leaks and it's unknown if the PO put a too big size on that's why he's double checking 1 Quote Link to comment
datzenmike Posted September 10, 2021 Report Share Posted September 10, 2021 Fuel lines rarely leak. If replaced, even more unlikely to be leaking again in it's lifetime unless damaged. Too big is fine. Look down on the passenger side frame by the starter where the fuel line becomes a rubber line. Pull it off and measure the rubber hose. I think the return line is the larger of the two. 1 Quote Link to comment
