Fuel system mods
This was a very popular topic back in 01 and 02. My new 02 truck was quite noisy had a sound like someone taping on a coffee can at idle. So I have done it all, Hutch Mod, DAHL pre pump water separator and filter, Regulated return, changing out the #8 LL injector for an AD and a return to tank fuel cooler. From a noise perspective he most effective thing that actually had positive results was the Regulated Return system, but one should be aware that it drastically increases return to tank fuel temps. Opinions differ because the variables are seasonal as well tank levels. In Alabama summers at 1/4 tank on the interstate my tank temps would get to 170F, with the cooler I rarely see more than mid 130's F. I choose to cool it down, many don't. But at least in cold climates with a RR your wont have to worry about cold fuel as much.
If one does the Hutch mod, which I would again, it's a given you will need a pre pump filter. Get a good system like the poster above has, or one like mine a DAHL 100 and get some additional benefit of actual water removal from fuel, it's in there and the stock filter assembly is worthless.
I probably would not change the #8 LL injector unless I was in there for something else, it made no difference for me except the 250 bucks and sore back.
It was about this time that many people were making mods in their systems that produced entrained air and that seemed to give birth to the air seperators, dang they have always been expensive. I really don't see the need.
