Any suggestions on how to get the oil out of the HPOP resevoir, so I can take the HPOP out and replace it.

 

You can suck a little out of it through the plug on top, but you'll end up making a mess eventually. Pull the IPR or just pull the HPOP and get it over with. The valley is easier to clean up with the HPOP out of the way anyhow.

 

Use a mighty vac (I think that's what its called) and suck it out. Then put rags around the base and PULL IT!!!
