Changed fuel pump, reran fuel lines to factory tank.
It turns out the factory tank was bypassed and they were using an auxillary tank, I am thinking the auxillary tank wasn't vented and it built up pressure in the Arizona heat and pushed past float and drained tank and filled motor. No other problems found and the truck runs great. The Edelbrock needs a good tuning but other than that all is good. Good oil pressure, runs cool and smooth.
Thanks for all the suggestions.
