Filling the HPOP? Overfill?

[DENALI]

My wife, bless her, changed the oil herself in her truck. However she didnt fill the filter before replacing it. It started then lost power and died and wont restart. I am pretty sure the HPOP got drained and is now empty. I know the level needs to be 1/2 inch or so from the top but curious if it matters when filling if it gets totally filled to the brim. Thanks

You actually can't overfill the reservoir, it has a hole at the top that spills the excess supplied by the LPOP back into the engine.

Good to know as she will be the one refilling it! Thanks

I have never done this on my PS, or any other vehicle I've changed oil in. Never heard of it causing a problem either

It's just good practice really. On a filter that holds a few quarts of oil it could mean a few less seconds your engine has no oil pressure.

yeah thats why at times if you drain your oil real good and dont prime the filter, you hear a cool knock for a few seconds cause of that much oil has to be pumped through the filter and back to the engine. i never really do it to much but have been lately, just to fill it up half way so its not to much of a pain to spin on there.

If she already has 15 quarts in the engine, won't adding oil to the HPOP result in having it then be overfilled?
