Seems to work as it should
So far so good.. I Purchased on June 8th, 2025 and got it the next day. I’ve only had it installed for 6 days so far.. Installing went smoothly once I removed bed.. (removed bed completely to do some rust removal and sealing) truck started up 1st try after install. Only thing I don’t like is having to cut harness to use updated plug. No wiring instructions.. hopefully it will last years to come. I will update review later to let people know about longevity..

Fit 03 Silverado 1500 4.8
Fit and tested out to specifications fuel gauge is a hair different reading than the previous one.Trailer jack knifed and really twisted the so called truck, busted torsion bar mounts and pressure regulator vacuum line(??) making it run full pressure all the time which I think caused the fuel pump to quit days later. Cheated and cut hole in box bed. This is at least the 2nd pump replaced the one on it was aftermarket.
