Well, I had one of the Airtex 3270 fuel pumps installed on my '97 GMC 1500 yesterday by a local garage whom I trust. The truck has 94,000 miles on it and this will be the third replacement fuel pump. My dad owned the truck for its first 50,000 miles. The OEM pump lasted about 36,000 miles. The first replacement (don't know the brand but it was purchased at O'Reilly) lasted about 20,000 miles and the last pump (a Carter P74167) lasted a little over 37,000 miles. I had never heard of the Airtex brand until I looked them up on the net last night. The mechanic who towed the truck home on Sunday suggested that I replace everything when I had the pump replaced (screen, filter, wiring harness, etc) which I did. I will be replacing the filter every six months so we will see how it goes. I hope Norwood, etc, are wrong about these pumps. I know that O'Reilly and Autozone still sell them in this area. You can get the Delphi brand but I am not sure they are any better and they are definitely much more expensive (though not as expensive as the labor, etc to replace the pump). Since nobody has posted on this link in a couple of years maybe the Airtex people have cleaned up their act a bit.
