Chasing a fuel leak on a Cessna 172 that took 3 days to find
Everyone told me it had to be the injector lines, but after swapping those twice the drip was still there on the hangar floor in Wichita. Turned out to be a hairline crack on the fuel drain bowl that only showed up under vibration, has anyone else had a leak that defied all the usual suspects that long?
Been there man. Had a 182 with a mystery drip that turned out to be a pinhole in the fuel sump drain valve, only leaked when the plane sat a certain way on the ramp. Took me almost a week of pulling panels before I found it.
