LT5 fuel pump? - ZR-1 Net Registry Forums

Welcome onto the boards there limo...

I put an Airtex in my '98 GMC [$323 from Advance], against recommendations of others w/A-Tex experience. The rap was that they fail often, and pumps can fail from getting hot. Gasoline keeps them cooled.

I keep my tanks full, so mine never got hot. None-the-less, it went belly up after 2 years. I had a ton of crud when I did it last month. The in-line filter was pretty plugged too.

I replaced it with something besides AirTex ($40 on eBay). I might get what I paid for, and maybe not.

I emptied the tank, filled it with aquarium gravel + some soapy water, and shook it for about :20. Then rinsed til it drained clear, dumped in some motor oil + WD from a gallon can to coat the tank interior and stop flash rust, the installed, and fired it.

Did you get fuel pressure tests done?
