Maybe so. What I do know, however, is that this particular pump has a Limited Lifetime warranty. That means that I get a free one when this fails in 6 months.
Changing the fuel filter every 15k will ensure the AC Delco or Delphi pump will still be operating when rest of the truck is a pile of dust….
I don’t have a clue what the warranties on the Delphi’s in my 96 truck, 96 van, and 02 van are, but once I learned the importance of changing fuel filters often and frequently I have never had to change a fuel pump. And because I own four 1st gen Vortec powered trucks and vans, a 3rd gen Vortec, and GM turbo diesel, this causes me great joy…..
My 97, 01, and 06 trucks all have the original AC Delco pumps on them with around 400k miles combined. We can safely assume the warranties expired a long time ago.
My 96, 96, and 02 Delphi’s have around 300k miles combined.
