Quote: If the pickup isn't reaching the bottom of the tank then you can't get all the fuel...Try adding fuel & see if it will pick it up...Could be a bad pump, or a plugged filter or fuel line, if it's a big block it could have a worn pushrod.... good luck with it..
Randy I agree , but once the fuel level drops to a point that the pickup can be exposed to fuel and air it will stop sucking the fuel.
A fuel tank will never truly empty unless the pickup is in a sump and it the lowest point in the sump ...
100% Any source of air, IE cracked fuel hose, a pinhole, whatever, the pump will suck air not fuel...
