    How to remove the Bosch VP44 Injection Pump the quick and easy way. Takes approximately 45 minutes for me to remove the VP44 Injection pump.

     

    Remove the Mopar1973Man Crankcase vent (if applicable)

    Using a 10mm socket remove the four air horn bolts and one dipstick bolt.

    Move the grid heater and intake horn out of your way.

    Pack a shop rag in the intake to prevent stuff from falling in the intake manifold.

    Using a 13mm socket loosen the 3 bolts holding the APPS sensor and unplug and move over toward the driver side fender.

    Now unplug the VP44 main connector and wire tap . This connector is a two step plug lock. Pull the release tab and wiggle the plug out then pull a bit more on the release and the plug should release fully.

    Now using a 10mm loosen the 3 bolts holding the 1,2,4 injection rail in place. Using a 3/4" wrench loosen 1,2,4 injection lines.

    Using a 3/4" wrench remove the overflow valve banjo and remove your supply line (may differ from mine being a big line kit)

    Now remove the crankcase vent. Just unscrews normal right hand threads. Do not pry on the nipple. Use an oil filter wrench or a strap wrench to loosen stubborn vent covers.

    Now remove the pump shaft nut with a 1 1/16 inch socket.

    Be careful removing the nut and lock washer that you don't drop them down into the gear case. A stubby Phillips screwdriver and a magnet is handy you can slide it off the shaft onto the Phillips screwdriver.

    Using a 23mm socket roll the alternator towards the coolant bottle to bring the keyway on the pump gear to TDC position and then install your gear puller and pull the gear loose on the shaft.

    Now loosen the 3,5,6 lines but you do not have to remove the injection line set.

    Now you want to loosen the 2 bolts on the rear bracket with a 13mm socket.

    Extremely helpful. Had to undo the return and supply lines and the fuel lines were especially fun but a well put together procedure nonetheless.
