You have to pay to play. When your DEF pump dies don’t replace it with a knockoff and use an OEM AC Delco replacement. This is an easy install but does require the use of an advanced scan tool to clear the codes and get the truck out of limp mode. A standard scan tool will NOT work.

My 2018 GMC 3500HD Duramax was throwing a P1050 DTC. The DEF fluid was empty, but I know it was full. After replacing the bad fluid pump with the ACDelco GM OEM, I was able to clear the DTC and my truck has been running great for about a week now without any DTCs.

I purchased this AC Delco replacement part instead of am aftermarket part. Within less than 2 weeks / 800km of driving the emissions system warning came back on. Thinking it might need ECU reprogramming to acknowledge the new part I took it to the dealer who confirmed that the warning was because of an "internal failure" on this AC Delco replacement heater. Not even worth the time, effort, or hassle, and definitely not worth the purchase price.

Fits my 2018 2500 and works fine. You have to drive it a bit for the computer to find it.

I had been contemplating deleting my truck after a previous pump didn't solve my problem. The pump I needed was for 2017 L5P Duramax engine and this was news to me that diesel trucks needed emissions items that are so expensive. My first replacement pump was purchased on Amazon and after the mess and stench of DEF fluid cleared my truck wasnt fixed and even took it to the dealership to check my work and the pump. Sadly it wasnt fixed and I still had to look a big warning on my dash screen and had to remove that pump, deal with 2.5gals of DEF fluid wasted($21 wasted) and my truck wasnt fixed. The refund and return policy of Amazon is the best but I just wanted my truck fixed. Now I ordered this pump, learned from previous mistake and only put 1 gal into the DEF tank and went for a drive to see if the problem was fixed. Initially the warning was still there, but after about 20mile drive the check engine light was off which was a sign that this pump worked 50% of my problem was solved. I pulled over and the warning was still showing on the dash but no check engine light came back, so I spent another $21 on 2.5gal bottle of DEF fluid(a full tank is 5gal). I waited for about 5mins, turned the key forward without starting the truck and the warning finally disappeared which meant the last thing to do was check the level. Scrolled through the menus(which were not available before) to the DEF level screen and it read"OK". Drove home with no other problems and now I am happy my truck is fixed for now.Update: Code for DEF level came back again along with def heater and my truck went into limp mode in Oct 20203. Now I have a big shiny lawn ornament that is a 2017 GMC Sierra Crew cab Long-bed dually because of this damn DEF pump again and now the truck is speed limited for the same issue.
