thanks for all of the suggestions .i was wondering about the pump but thats going to be the last resort.im probably going with the block in the fuel line.i replaced the fuel line going to the rail.i also thought about the gauge you can get a bad one but im not sure it would make the motor backfire on decell, and run so rich but i have seen weirder things tho.going with sleepinsol i do have an adjustable regulator but it craped out on me and its weird but i dont blow out black smoke at wot.but thanks everyone
