Fuel line fittings LS JK

Hey guys,

I tore a fuel line somehow on my JK and I want to go to flexible braided stainless lines. Does anyone know what fittings would go from the stock tank and into the 5.3 fuel rail. All I can seem to find are for guys doing fuel cells.

I'm almost sure it's 3/8" hose but correct me if I'm wrong. It's stuck out on the road otherwise I'd just rip it off and measure it.
Get to do some parking lot repairs and I don't want to be running around looking for parts.

Thanks,
Sean

Stock is 3/8" nylon tube (portions of the fuel supply line are metal but you could replace with nylon). EVAP purge line is all 3/8" nylon. NAPA sells repair kits that can patch your lines to get you home. Would be good to find out if your lines were upgraded/replaced with the swap... I don't know about the 5.3 fuel rail fittings.

The fuel tank has the evap and fuel lines terminate at about the transmission cross member with 3/8 quick connect fittings. From the tank, the fuel line is male and the evap is female. NAPA also sells repair kits with compatible fittings; they include some tubing, the quick connect fitting, and a brass barb coupler to tie back into the original line.
