Engine Mechanical problem
1988 Toyota Van 4 cyl Two Wheel Drive Automatic 200000 miles

I let the fuel go too low in my van and it stopped going up a slight hill, i got it started again by dripping fuel in to the top of the engine and a mate turned the ignition and started it at the same time, but now it takes a little longer to start it when it is facing up on a hill, have i damaged the fuel pump or do i need a new fuel filter.
