Yesterday I had The Murray out for a short run. After about 8 miles the engine lost power, sputtering and died.

D'OHH! due to the new fuel selector I now have a separate switch from the OEM to flip tanks. So I was showing full on the unselected tank when the selected tank was empty. I just finish making up a relay so the OEM switch can do the job again.

So once that was discovered I flipped the switch and off I went to the gas station to fill up. It only took 80 litres (20US gals) to fill it. So my gauge reading full on one tank and empty on the other seems right, but why? There was only one small hill, maybe 25ft high rising and falling in about 1 mile so hardly enough to throw the fuel from one tank to another, besides I was running on the Aux tank which should fill up more in hills. Otherwise the road was fairly level.

I had all the tanks down last summer while the engine was out for a rebuild. All the hoses were replaced at that point, including the filler hoses.

I do have EFI and the return line is in the filler line, but I would expect the Aux tank being the front one would again get more return fuel than the rear (main) tank.

Any ideas?
