Don't know squat about the fuel pumps. If it's JUST the pump itself, I highly doubt there is any difference between Dakota/Durango.

The FMS 24LbHr injectors are GREAT! They sure add ALOT of fuel though. Unless you'r running boost or a 408, I'd look for somthing a tad smaller me thinks. I had 24 Lb/Hr injectors in my 95 and it was ALWAYS rich... =(

Seems to me that you are starting at the end of your modifications instead of the beginning.

Size is not always the way to go. A stock Dodge 21 pound injector may on average only be delivering 19 to 20 pounds. A more precise injector will come much closer to the rated pounds per hour. As with the Ford injector or a Marren injector.

Injectors rated for 21 pounds are good for about 320 horses. If you must change out the injectors I would not go over 22 pounds and would purchase the Ford. As for the fuel pump check the pressure before going off and spending the money and dropping the tank.

I would put a lot more work into my ability to inhale (TB and intake) before I worried about exhaling (headers.) My truck can easily exceed 140mph and it has even dawned on me to go with 24 lb. injectors. I've considered a set of 19 lb. FMS injectors just because I believe they have a better spray patter and thus possibly more efficient.

The last thing I did was to add headers and that seemed to be a bit disappointing. If I had the whole thing to do all over again I would have put in full length headers.

I would have to agree with this statement. I've heard decent results with normal "shorty" style headers, but to get any really kickass gains, you need Longtubes... Sucks for us Pre 97 guys cause NO ONE MAKES EM (that I know of...? Anyone feel free to chime in here... P L E A S E )

Most of the restriction in your motor in on the "inlet" side. I'd get an intake and a TB long before headers. I'm actually concidering NOT gettin headers on this truck, but I might get my manifolds ceramic coated, for heat transfer and looks purposes
