A bit of a stupid question - but I dont know so Im going to ask. I talked to a guy that told me 03/04's dont have the VP 44....so Im wondering what you guys have for an injector pump.....thanks.

 

That's right, the VP-44 is no more.

The injection pump is a simple high-pressure pump that keeps a constant pressure fed to all the injectors simultaneously. It does not perform fuel injection duties. This is now done by new electrically-controlled injectors which can deliver 3 injection pulses at a time: 1 to start combustion, 1 main combustion pulse and an afterpulse for emissions reasons.
