Fuel pump DELPHI or AIRTEX

Running a Delphi for the last 4 years. No problemo

I went with Delphi and so far so good but only have about 3k miles on it.

The Delphi in my wife's tahoe is still kicking ass 5 years later.

Delphi is the only way to go unless you don't mind replacing it again every year with cheap parts. A fuel pump isn't something you want to cheap out on I'd say for safety reasons.

About 1-2 years ago I put a brand new Delphi pump in my 5.3 Silverado. Been great since. Don't let that tank get below ¼ and it'll last a LONG LONG time.

I'm on my 5th year on Airtex in my gmt800 and gmt 400.

I used this to get mine up and running. Although it can't handle factory TT power

I had the fuel pump die on my vehicle, I replaced it against my better judgement with an airtex (cheapo) pump because it was available and cheap. 6 months later I’m dead on the side of the highway again. Warrantied it with the same pump… lasted 4 months this time before I was stuck again. Replaced it with a delphi brand (oem supplier and almost 3x the price) and it lasted 6 years until I junked the vehicle due to rust.

Proper diagnostics aside, if you end up replacing the pump, stay away from Airtex.

Delphi is hit or miss. One of my techs just put a Delphi in his Honda Pilot and the pump failed after about a month. Fortunately, it was just the anti-drain back valve that failed and only caused a hard start instead of him being stranded somewhere.
