1. Ensure the little filter inlet screens are clean.
2. Do you have fuel filters in the lines? If no, add 'em. If yes, are they staying clean?
3. Did you confirm no crap in the tank that might be intermittently and/or blocking the outlet?
4. When replacing the fuel pump, some folks have had to loosen the passenger side motor mount and jack up the engine a little on that side to get the fuel pump in.
