checking hpop oil level
i know the screw is on top of the pump, but it is the little hex screw closer to the right side of the pump, i am looking for a bigger fill screw but all i can find is a small hex head screw. i changed the orings last night, but will the pump come back to the correct level after i drive it for a bit, or do i have to fill it up some??

Thanks. I have only read a little on injector operation. If you know of any links with more info on the operation of injectors I'd like to learn more about them. When you say "fire them" does that mean that the HPOP causes the injectors to open (and allow fuel into the cylinder) by using the oil (10W30 or whatever) to pressurize the injector to the open state?

just wondering, i know someone said to add fresh oil, but i just changed it about two weeks ago, so if it will come back to the correct level i will leave it, or should i check it ?

It will come back up to the correct level, it just may be harder to start. When i changed teh HPOP i didnt add any oil, just cranked it about 3 times and she lit, sounded really goofy at first, then straighten out.
