Review on Delphi FG1237 Fuel Module by Gary Perry

If you have starting problems, starting problems or low fuel consumption then this is the best solution. Rather than repairing/rebuilding the original assembly, this is a fully assembled and ready-to-install pump. Delphi is an original equipment manufacturer, so you can be assured of a high quality, reliable pump. I have compared the original Nissan pump and the Delphi pump assemblies and the Delphi is much better (e.g. dual sweep contacts on the fuel gauge instead of one, two springs on opposite sides with a guide pin/rail in the middle, which ensure even pressure instead) . from a weaker spring that is off center, a larger and stronger fuel pressure regulator, a fuel float that can pivot and center itself rather than being cheaply bolted and attached, the list goes on). I've been using this pump for about 2 weeks and it's day and night, my car starts, runs better and I have better fuel mileage every time. I've also noticed that my injectors are quieter. Not only does this pump come with a new O-ring/tank seal, it also comes with a new steel retaining ring. I couldn't be happier with my purchase. I paid $155 for my item which saved me hundreds of dollars and ended up with a much better repair. This is the only way to maintain your Sentra from 2002 to 2006. FYI - TSB Service Bulletin for: NTB05-052a to address the deal. The parts you would use to rebuild your old pump assembly (and in the kit you are effectively reusing your original pump).
