I know it's known issue, but still can't find solution, bought my gunner in Feb 2017 and it's awsome except one thing... high pitch noise from fuel tank. I've read all about it I could find in internet, no it's not cap, it's certainly pump and as usual dealer says "no abnormal sound" (well, first time they said that's pump and changed it, at least they said so). Does anybody tried to fix it? My last idea was to cover pump with not dissolvable by gas material. Is it possible to disassemble it and figure out what makes that noise?
