atomarc,
The pump will gush out at the carb for only a few spurts and then occasionally. I then check the bowl and see the bubbles from the intake line.
I consulted the exploded view in the manual and see how the stop valves keep gas in the "upper" line. According to this, I think I have a bad leak in the intake fitting. That is the only place air can come from. The diaphram should be OK.
At this point a new fitting, and relocating the gas tank above the pump should solve this. My thinking is that the lower gas tank is sucking the fuel back due to a leak at the intake. Then it drains the bowl and eventually gas slowly leaks out the fitting. Could I be right?
Otherwise I've already adhered to your suggestions. Thanks Stuart.
Kyle
