I've had a grudge against Delphi ever since a new one caused the fuel gauge in our old '05 Yukon to read incorrectly.I don't trust Delphi that much. We put one in our 97 GMC farm truck and it only lasted about 11,000 miles and about a year and a half.
I just put a Delphi pump in the 92 Cavalier only because it was the only one that I could find at the time that came with the entire module. Years ago I had just replaced the pump itself and used the original module but back then I could still get an AC-Delco pump. Not anymore.
Honestly each time we replace a complete assy we should probably reference the ohm range for the gauge and verify before installing. It's soooo frustrating to have a working gauge, go through the work and then have an inaccurate gauge.
