Hi, I know the DDRP is not really a performance upgrade but it is new and came with the truck. It is mounted already but I plan to relocate it near the tank. The kit comes with 3/8 line, At what point do I want to go to 1/2 inch line? I am going 1/2 from Filter housing to Injection pump with better fittings. My plan at this point is just a Quadzilla tuner, Will DDRP keep up at max level? I will upgrade Lift pump at some point.



Thanks

 

How much fuel can it flow thru the 3/8ths line?

 

I just spoke with Vulcan Perf who make a 3/8th and 1/2 relocation kit, they suggested the 3/8 kit as it will flow plenty of fuel for 600 HP plus. I'll do 1/2 from filter housing to VP.
