my eldbrock mechanical feul pump isnt getting enough feul starving my engine about 1/2 track. i was thinking of running 1/2 inch lines and an eletric feul pump like a holley.my queston will an eletric pump pull gas from the tank. i have no feul pressure gauge now but when i return from a 1/4 mile pass the plugs are white,then when i drive home(about 10 min) at 3000rpm the plugs are brown again.i think its starving for feul?it only has that gage when it shifts while racing
