Out of gas with 1/3 tank remaining

Postby David2953 » Sun Aug 14, 2016 3:37 pm



My 82 GL1100 just ran out of gas, but there was 1/3 of a tank left in it. I figured the mechanical fuel pump had quit and I had no tools with and didn't think I could fix it even if I did. I walked the 4.7 miles home and got my car and trailer and picked it up. Back in my garage I connected gravity fuel and filled the carbs and the engine started and ran fine. The fuel pump also pumped gas out the line I had connected to its output and collected in a bowl. It seemed to have fixed itself. I took the pump apart and one of the disk valves was not able to seal air. The pump would pump gas fine, but not air. I figured an air pocket got to it from the fuel filter when I went around a tight left-hand turn and that must have been the cause. My fuel filter had been laying horizontally behind the carbs with a big air pocket in it. I moved it over as close as I could get to the petcock so it is in a more vertical position to prevent the air pocket. I'm hoping that will take care of it. I am also carrying a pliers so if it happens again I could disconnect the fuel hose at the pump and suck the air out.

Mine always has a air pocket in it(never full) and I don't have any problems and it is horizontal(in the stock location).I might be wrong but i think that's normal.

Yeah, the filter never looks full.

On your test run and if it happens again, pop the fuel cap loose and if you get a big rush of air your fuel cap vent may not be operating properly. Most people soak the cap in seafoam to get the rust corrosion loose or just spray and clean.

I did remove the gas cap, because I know about the vent problem, but there was no rush of air. So, if that air pocket in the fuel filter never causes a problem, when why did my pump stop pumping?
