I know it's on here somewhere. I've done 9 different searches and can't find it. If one of you guys has the number within easy reach could you please post it here. I want to change my lift pump before I install the EZ.<br><br>Thanks,<br><br>DeWain

 

I think this is the Cummins part # 3990105.<br><br>I got it off the Tech Facts section of the website. <br><br>DB

 

Thanks DarrellB! I looked there too, but I must be search-challenged. Now that I know that it's there, I'll give it another try just to see if I can find it.<br><br>DeWain

 

Doh!!!!!!! I found it. DB, thanks for the help.<br><br>DeWain

 

The loft pump we've been using lately is Cummins # 3990082.<br>Have fun.

 

Those are both valid part numbers. The 3990105 is just the lift pump by itself. The 3990082 includes the lift pump and the wiring pigtail adapter required by the 98-99 trucks.
