Is it possible the pump you got was in the wrong box?

Best of luck.

Long story short, every pump that I ordered and every pump the shop ordered and every pump the warranty company ordered did not fit, even though it says it does. 2009H3T Alpha fuel pump is of itself. From what we all can see supposedlyIt does not fit the 2008 or the 2010. The fuel tank is different for the 2009. It does not fit any other year which is why GM decided they weren’t gonna waste time making anymore? And the original fuel pump was rebuilt and I just got the truck back yesterday. Here are some pictures. What a pain in the rear.

Got a small video explaining how every pump we received was wrong

yes sir that’s exactly what they ended up doing. I told them your recommendation from the beginning, but they had to go through all these ridiculous steps because I have a Warranty on this truck that’s about to expire and I wanted them to pay for it. And they paid in the end so cool

Your FPM is the rare poorly designed 19206830:

Replacement FPM requires rotating to properly fit:

hummerz your pictures show one has a return and the other does not. you might have used a 2003 pump picture.

does anyone know of any fuel pumps available for a 2009 H3T Alpha?

did you find a replacement pump yet ? i was having the same issue but i found a solution !
