Fuel pump AIRTEX or WALBRO

I've used the Walboro 255 with stock lines/regulator and an analog fuel pressure regulator gauge right in the engine bay. No spikes, even when the pump is "hotwired" and the engine is off.

I have a used 200lph walboro. It’s got maybe 15-20k miles on it. Was 100% functional without issue when I pulled it.

Buy a Walbro brand replacement pump for your truck and youll never buy another pump again.

I used a Wallbro, have had very good luck with it.

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

I used a Wallbro, but I think they make the Delco's.

The car doesn't like to start as quickly as it did with the two pump setup. As the car gets hotter and I do a few restarts while running errands the car is even harder to start. Yesterday resulted in me being stranded in my kid's daycare parking lot for about 5 minutes before it eventually started up again. The pump still fires like it should in the acc position and the car otherwise runs fine which tells me the fuel pump is doing its job.

I ordered an Airtex pump for a secondary vehicle I had and it didn’t make it two weeks. What a pisser.

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.
