Fuel systems for these trucks are very simple once you break them down, and it has been covered multiple times here.
I think it would be good to have a sticky for this as its gotta be the most discussed thing in this section.
But basically your gonna either have a sump or draw straw your choice I prefer a sump then use -10 line to a water seperator then pump then fuel filter then use -8 line up to the heads split that using a t or y block to a -6 then out of the heads into the regulator then just -6 for the return line. This will get rid of the expensive factory filters.
Unless you already have the reg return using the stock bowl and everything up to the engine then you would just get the fuel up to the bowl with the -8 line.
Another thing i want to look into is using a stock 6.7 pump, i believe they run around 55-65 psi. Im curious what they flow though... somthing id like to look into.
