I'm working on a 2003/04 Dodge Ram 2500 with a 5.7L V8 Hemi. It will not start, I've been told these are notorious for fuel pump issues. I bought a fuel pump tester, and I just need to know what the PSI for this make/model fuel pump should be, before I have to drop the tank and replace the pump.

400 kPa +/- 34kPa (58 psi +/- 2 psi) or 339 kPa +/- 34 kPa (49.2 psi +/- 2 psi) depending on VIN, etc.
