welcome to DTR transfer pump and lift pump are the same the lift pump is on the drivers side under the fuel filter just to the rear get a fuel pressure gauge asap before any mods start the pressure gauge can be installed in the bottom of the fuel filter housing or at the IP bottom of fuel filter is prefered location. there are lots of venders who sell FP gauge kits, i like piers.
