I called the corp office for M&D they told me that the shop sold me the wrong pump, So tonight Im pulling the vp back off.

Yes I understand its not the full system, at this point I cant afford the full system.

Man this is some serious big boy toy prices.

 

Is your truck an HO or SO??? What pump did you get an HO or SO pump!
They are interchangeable! If you put a SO pump on an HO engine you will lose a little low end but with a power box you can make a little more. Don't you have a box? Find out where the vp is rebuilt and get a reputable pump or you will doing this again soon. Same with the lift pump. Check your pm.
