Is this normal? I don't have any problem starting the truck, even after it has sat for two to three weeks. | | | | | Joined: Aug 2005 Posts: 6,377 Ex Hall Monitor | | Ex Hall Monitor Joined: Aug 2005 Posts: 6,377 | You may have a bit of crud holding the valve open just a bit. It shouldn't drain back. If it were me I'd buy a spare pump to keep on hand in case that one gives it up. If you haven't already done so it wouldn't hurt to put a filter between the tank and fuel pump.
