I want to upgrade with with the scotty smart fuel system or the one that Jannetty offers. The only difference i can see is the Jannetty is 6an and the Scotty is 8an for the lift pump to the fuel filter and 6an for the rest.

Any thoughts

 

i cant tell you about the jannetty set up . but the scotty set up runs 8an from the lift pump all the way to the vp44 and is 6an on the inlet side of the lift pump. i have a cummins stock replacement lift pump thats been on here for about 12k now and i still get 16.5 to 17psi at idle and cant draw it under 13 psi at wot going up a good hill.
