Alright guys I am putting my fass 95gph without filters from my duramax to my 24 valve cummins. I was just wondering what I need to do to increase the pressure to that required by the cummins. Also is there anything else I need to buy or change to make the swap? Thanks guys!
 
You will need to order a different spring at your desired pressure or possibly stretch that spring a little. Atleast this is what I've read.
 
Get with your local FASS dealer, or whoever you purchased it from originally, they can tell you just what to do.
 
Wiring harness, fittings, and hose should be all. If your pump was a standard model the psi should be ok as well
