Jim,

I still have an unanswered question lingering: IF the anti-siphoning
valve is in question, would any gas be coming out at all from the fuel
tank? Or could the valve be a build up type thing where enough pressure
occurs and the valve kicks on(shuts the fuel supply off)?

I'm thinking about taking it to a different mechanic at this point..
although I might try to look at the anti-siphoning valve, and then also
unhook the fuel hose from the fuel tank and put it in like a 5 gallon
tank of gas and see if that works.. i think that would tell me a lot,
whether or not it is something BEFORE the fuel filter.. the mechanic
never really even did any testing on what came before the fuel filter..

I think you are on the right track now.

It's just a spring and ball check valve. Junk getting sucked up from the
tank could be clogging the valve then falling back into the tank when the
fuel pump stops. Fuel lines have been known to collapse. Tank vents
sometimes get clogged. Pickup tubes can develop pinhole leaks. You've
already replaced the expensive stuff. The rest is relatively cheap to swap
out. Also you should look into what turns the fuel pump on and off.
