OK, so what are the differences in these fuel pumps? I want just the same as stock. Truck: 2002 2500HD 8.1L

DELPHI Part # FG0271 {MODULAR FUEL PUMP ASSEMBLY}
w/o Evap Emissions Sensor Stamped TCU

DELPHI Part # FG0053 {MODULAR FUEL PUMP ASSEMBLY}
w/Evap Emissions Sensor Stamped TCF

I see the with and without evap emsn sensor, but what is this? How do I know If I have one?? The pumps are $.10 difference from Rock Auto...10 cents, come on.

You can check under the hood for the EVAP solenoid on the intake manifold. I'm not sure where it is on the 8.1, but it should be on the intake near the throttle body. I'd say your truck probably has EVAP, most do.
