Review on 🚚 Chevy Pickup Silverado GMC Sierra Fuel Pump 1999-2004 4.3L 4.8L 5.3L 6.0L 8.1L w/ Sending Unit & Fuel Pressure Sensor, Replaces E3500M by Kevin Hutchison

I had to raise the bed 3 times and the pump was making a low pitched groaning sound on the return line. The pump seems to be working fine, but I'll update when I have longer runs. I pressed the button 3 to 7 times simultaneously (wait 4 seconds). I also partially cranked the engine 3 times. (Once) I had to leave the truck for 30 minutes into the night between starts to make sure everything was working properly and starting normally. The PUMP makes a low moan when I press a button. Update: still has a long startup time. UPDATE: LONG START TIME DUE TO FUEL PRESSURE REGULATOR DAMAGE DURING PUMP CHANGE. NOT A BAD PUMP! SORRY AMAZON IT WAS ONLY A RANDOM TIME.
