I have a 2015 Silverado with a 5.3 that I’m doing an AFM delete on and while everything is apart I need to change the HP fuel pump as it’s not maintaining pressure and causing hard starts. The problem is that I cannot find a pump anywhere. Anyone have any knowledge as to where I can get one or if there is a replacement that would do the job?

 

have you tried rockauto?

 

Rockauto was my first choice. I have tried all of the major websites, even some sketchy ones, and every parts store I could think of. It seems like the part is discontinued and there are no aftermarket replacement options.

It’s good to know there are some out there. The only down side to the place you sent is that they only ship within Canada, and I’m in the southern US.

 

plenty more where that came from (web search)

(you'll need to verify the part number yourself since you didn't provide one)

 

I really appreciate the assistance! I didn’t know about these sites. Now I can finally get my truck finished and back on the road!

 

I didn't know about these sites either. I just typed "gm 12711662" into google.

 

Did your fuel pressure sensor go off too?

 

No, fuel pressure sensor was fine. I began having long starts, or sometimes no starts due to the HP system only getting up to around 420 psi
