It delivers fuel efficiently, ensuring smooth engine operation and consistent performance. The build quality feels robust and durable, reflecting the high standards associated with AC Delco products. Overall, the AC Delco fuel pump has restored my vehicle's performance to its best, and I couldn’t be happier with the results. It's a top-notch replacement part that offers reliability and peace of mind. Highly recommended for anyone needing a dependable fuel pump at a great price.

Worked great for my 2001 Chevy suburban 1500 4x4 the entire job took me about 2 hours With a few jack stands in the garage it’s definitely a 2 person job. delivery was sooner then expected the wire harness fit perfectly I didn’t have to cut or splice and wires. I just did the job today so far it’s runs great. Definitely would recommend.

Took these OEM fuel pump and accessory pieces, and shared a YouTube how to, with the guys at the nearby service station, where the old fuel pump failed (while backing onto street in lunch hour. They put it on, and my dear, comfy Suburban thinks it is brand new again! All for less than the cost of a car payment. Love that my gas gauge is accurate again. My advice: if your gas gauge is inaccurate, it is the first sign of trouble to come with your fuel pump. Just go on and replace the unit before something tragic happens. Needing to replace fuse or relay is a sign of impending doom. The fuse blows before you do further damages. The relay failed when the guy at the service station kept trying to start it. Never let your fuel pump get stressed out by running out of gas. Always refill at half tank. Just do it. That habit will save money and assure your safety. Also, you must install a new pigtail end on the vehicle side of the wiring harness. Both connections must be new.

Complete unit fuel pump and fuel sender with screen built inside. No issues on installing. I did not need to replace the included pigtail since my Yukon already had the proper plug. After 7 months of usage the fuel guage became erratic and finally only worked from Full to 3/4 tank even after driving over 350 miles per Odometer. I removed the pump/sender and used a volt meter to verify the sender ohms reading: 40 [E], 250 [F]. I moved the float up and down and got proper ohm readings throughout the range. I then tested the wiring and cluster guage functioality without any issues. Therefore the issue had to do with the sender float arm. Upon further investigation I noticed the float would not rotate freely on the float rod. I had my old pump/sender and compared the two floats. The old one had about 1/8 inch clearance against the float rod and spun freely, the new float was rubbing against the float rod and would not spin without effort. I used a pair of needle nose pliers and straightened out the rod ending that held the float in place enough allowing more clearance against the float arm and it spun freely. I re-installed the fuel pump/sender and recorded the stabilized ohm reading after letting it acclimate before hooking the wiring back up. The guage started reading correctly again based on my calculation of the stabilized ohm reading, trip miles, average mpg, and fuel tank size. The guage appears to be reading correctly now.
