I used a steering wheel puller. You will need to find two bolts that screw into the pump gear though. I think the the bolts are 8mmX 1 1/2" long. Another tip to help ya, there are 6 injector lines, I removed the ones for cylinders 1,3 and 4 I believe. The group of lines that feed cylinder #6 you can leave alone just remove them from the back of the VP44 and you can push them toward the block gently to allow enough room to remove the pump. If needed loosen the hold downs for those lines to give you a little play. If you want to remove those lines you will need to remove the engine lift bracket, plus getting to #6 is a pain as well. You may also need a little heat on the gear to get it of the pump shaft, I did on mine. Make darn sure that the key on the pump shaft is at 12 o'clock before pulling the pump so that the woodruffs key on the shaft does not fall out and drop down into the front of the engine. You may need a small mirror to verify this.
It's not a bad job, I was a little intimidated the first time but, all went well and took me about 3 hours.
