I work in a fleet maintenance department of a major manufacturer. We service the forklifts and road tractors. We had a truck that would empty one tank and fill the other. My diesel tech plugged the lines on the empty tank to see if it would suck from the full one and it wouldn’t.
I asked if he was going to try to blow some air in it and he said yes. We took off the other fuel line and he was going to put a rag over it to catch any fuel that blew out. I asked him to hold on and I got a ziploc bag so if something came out we would know we found the problem. The clog cleared and some fuel shot out. I started poking at the bag and I felt something squishy. I worked it up with my fingers so I could see it and much to my surprise I saw a well preserved Frog! It was the weirdest result of any diagnostic we have done so far. I was almost crying I was laughing so hard. Talk about the last thing you would expect.
From now on anything that won’t run will be suspected of having “a frog in the fuel system”.
Joe have you heard a stranger diagnostic story than this?
