EDIT: I SEE NOW FROM BILBO'S POST BELOW THAT I AM ALMOST ASSUREDLY WRONG IN THE FOLLOWING SENTENCE THAT I POSTED IN THIS COMMENT:How are y'all getting the probe in there? Mine wouldn't go in at all, even after hand drilling out with a 5/16s.
It must go in the OTHER hole toward the top and the lower hole is just a sight hole for the timing mark when using a timing light? I should have noticed the difference at the time but I didn't. END OF EDIT.There are TWO holes - it goes in the bottom one.
SEE THIS TOPIC THREAD:

(I deleted a sentence here wih the above edit)
For anyone who doesn't know yet:
ALSO you need to fabricate a wrench to loosen the three IP bolts to move the pump if it needs adjustment and re-tighten them. Also you definitely should loosen all of the fuel lines where they connect to the back of the IP so you're not fighting against them and putting unnecessary stresses on them. I've never done this job (yet) but I would expect to loosen the fuel lines at least one full turn, or 1-1/2 turns except for the center fuel feed line and that one won't require as much because it stays in the center of the pump rotation as it's moved for timing. (I would use a flare wrench if I can get one on most of the fittings. I had to tighten the bottom one once and the center one to stop leaks and used a short 5/8 in. open end wrench.
PUT A RAG (or absorbent shop towels) DIRECTLY UNDER THE FITTINGS TO CATCH THE FUEL.
For wrench fabrication ideas, see this thread, from post #1 to #15 https://www.oilburners.net/threads/ip-wrench-cheap-almost-easy.45485/

Personally I am going to modify the obstruction wrench as user OLDBULL8 suggested in post #15 in the 'cheap IP wrench' thread. There are a lot of those for fairly cheap on ebay or you can get a whole SET at Harbor Freight for $15.99.
I believe those IP bolts are actually 14mm, and 9/16 in. is slightly larger than 14 mm. so either wrench should work.
