Interesting note. I just purchased a 96 Jeep Grand Cherokee with 200k+ on it. I know it will need a fuel pump soon so looked on rockauto to see what is available. Denso was the oem for the fuel pumps with a price tag of $329! The Delphi Bosch Carter and Airtex where just below Denso in that order. I know Carter was one of the manufactures used in the second gens but don't think Denso ever made them. Here is what they say makes them different from the competitors...
