Did some rototilling last weekend and was somewhat confused about my fuel tank and what it did.
I was under the impression that the injection pump is gravity fed on my 2610D. But after about an hour in 70 degree weather of tilling I noticed my red fuel cap was about 3 to 4 inches LOWER than normal. I unscrewed the red fuel cap 1/2 turn(Aftermarket with no bleed hole) and the tank sucked air in and the fuel cap rose to normal location!!!
Can anyone tell how this can happen on a gravity fed fuel system. Something must have applied a signifigant vacuum to the fuel tank. Could the injector returns cause this?? It is apparent I have no fuel leaks or no vacuum would have been present.
If anyone can explain this to me I would appriciate it.
THANKS
