Leaking fitting.


This fuel line leak was noted at the exit of a fuel pump on an RV-14. It is right above the exhaust pipe! One needs to be careful when having hoses fabricated by non-aircraft supply houses that the flares and fittings are made for 37.5-degree AN-type fittings, as opposed to the standard 45-degree automotive flare. This nut was checked and was tight, so it was a mismatch in the flare or a cracked flare.
