Take out the bolts as mentioned. I would pull my inner fender so you can get a straight shot at it. You could grind two flat spots on it with a Dremel motor, and then grip it with vise grips.

    2009-6-21u2002·u2002I have tried two different fuel pumps,both mechanical. I installed a new fuel pump push rod by comp cams with a bronze tip to minimize wear on the cam lobe and now I pulled the second fuel pump out and the rod is stuck It will rotate freely but will not move up or down.

Some pumps are sealed and cannot be repaired; check to see if there are screws for dismantling.
