Thanks Rob!

Someone mentioned a 5/8" pickup, aren't we supposed to have a 3/4" pickup on ours?

Early pumps were 5/8". By 1995 they should have been 3/4".

Just search for cavitation, several people can make their oil pressure go down when they go WOT, obvioulsy theyre sucking up air instead of oil. Some can do this with the stock pump, so you can imagine how much worse it could/would be with a HV one. I'm using a normal pump and have over 60PSI cold idle, and over 60 warm cruise...its plenty of pressure.
