Hey guys not very familiar with these engines, more familiar with the first gens. first off what are the diffenences between the injector pumps of the 94-98 p pumped trucks, horsepower specs and so forth? i am under assumption that there are some differences because i think i read something about this on the internet somewhere and i think i saw something about california trucks are also different. second, what kind of fuel milage do these trucks see with say a 4x4 five speed setup and 3.55 gears? thanks

94,95 manuals are 175hp, 94,95 auto are 160hp, 96-98 autos are 180hp, 96-98 manuals are 215hp. The 160-175 pumps have 131 delivery valves, The 180and 215s have 181 delivery valves. The 215 pumps have retard notches in the plungers. I think Ca trucks never had more than 180 hp. You can get over 20 mpg in a 5 speed, 3.55 geared truck.
