My truck is having 1/4 tank problems. Supply pressure drops a couple psi and is slow to build after cranking. And it stalls if the pump isn't running. I have already had the pickup out once trying to resolve it. Got better but not right. Wondering what can be done to modify the pickup to work better? Drilling or cutting holes in it? Replacing the plastic suction house with something else? I really don't want a sump because I think I'd probably rip it off or damage it off road.
