318 Can't keep fuel in filter, stalls when hot.

BTW, I have no carb spacer, I did not relacate the filter, or any lines. No return vent on the filter I just switched out to non alcohol fuel.

My problem was solved.

Another BTW...

The engine will idle for quite a while on the fuel in the bowel. As my video shows.

The empty or emptying fuel filter has vapor in it pressurized at 5 to 7 psi. The float is still high and is not needing to allow any more fuel in to the bowl. Once the float sinks enough the vapor is released pressure is around 2 to 3 and fuel flows to fill the filter and the bowel till full and the needle seats and the cycle repeats.
