A few weeks ago we hashed around fuel tank levels and different ways to determine the approximate amount. I drained the tank on my 54-3100 then put 5 gallons of high test in. Been working on gauge float. Put high test in and let it run out, getting the burps out of the valve train after setting for too long. Don't really want to go back into tank unless necessary. Where should 5 gallons of gas read on fuel gauge (+ -). Putting white gas in and run it out again to make sure ethanol is nearly out. If I put a 3/8 fiberglass rod down fill tube, how much should be on the rod? Doc.

Currently making 1954 3100 better than new and Genetics
