Hi everyone; I operate a 912is on my Super Petrel with a total of 52 hours. On my last flight, I felt a very strong AVGAS 100LL smell. Upon landing I found I had lost some 3 gallons of fuel from a leak from the pump into the hull of the plane. Upon inspection, it was apparently from a HOLE in one of the gas pumps. The enclosing of the pumps had some corrosion signs that this had been happening for a while, and only got worse enough to be smelled and detected in this last flight.
