Re: How Test Fuel Pump?
Just take the fuel return line off and see if you get any fuel out of the fuel filter housing. Fuel out when the pump's running means you've got enough pressure to overcome the spring and ball in the regulator. 50+ or so. If fuel keeps coming out for awhile after the pump quits, you've got something wrong with the regulator spring.
Check the inlet connection to the pump - notorious for allowing air into the system.

Thor's Hammer is a symbol of the struggle against chaos and evil. It's the weapon used by Thor against giants, monsters, and other trollish folk who threaten the common good.
