donalloy1 - when you get your IP back, use your mirror as required and make sure the indexing stud on the pump rotor goes back into the mating slot in the engine gear. Then loosely attach the 3 nuts on the back side of the gear housing to hold the pump in place while you install the 3 bolts through the fill tube opening. Again, you must be carefull when you install these 3 internal bolts. The first hole should already be lined up from when the pump was removed. Use your mirrir to make sure, and cram a rag inside to keep from loosing a bolt down into the engine. Use the socket magnet if you have one. If you don't have one, go get one. It is THAT important. I used red LokTite on my bolts, which is not called for in the TM however I saw traces of red LokTite when I removed my bolts, so I used it when reinstalling. Get your buddy to rotate the crank pulley nut with the pull handle until the next bolt hole lines up in the mirror. Trust me, the mirror is invaluable in lining up the holes. Snug all 3 bolts up and then go around again with your torque wrench set at the correct setting (in the TM). After these 3 internal bolts are torqued properly, go back to those 3 nuts on the back side of the housing. Loosen these enough to permit the pump to rotate, and then align the timing marks. Factory timing is the exact alignment, however most folks advance the timing by the thickness of the line towards the driver's side. Once you get the marks the way you want them, tighten all three nuts wrench-tight (as tight as you can hand-tighten them with a boxed-end wrench).
Once you get the pump on and everything hooked up, open the air release knob on top of the fuel filter, hook up the battery and turn the engne over until fuel squirts out the drain port. I stuck a piece of small rubber hose on mine and pointed it down to the ground to keep from squirting fuel in the engine bay. Once the filter is primed, tighten the air release knob and crack open all injector nuts. Make sure your batteries are fully charged, and crank the engine for 15 seconds, wait a few minutes to allow the starter to cool, then crank another 15 seconds, etc. It will require about 4 of these cranking sessions to fill the system. When you see fuel leaking at each injector nut, everything is primed. Tighten all injector nuts and fire them horses up.
If I can offer any additional assistance, send me a PM.
Hope this helps.
