Hi volume oil pump vs standard volume pump

Just another source of info on these pumps from Melling:
Technical - Melling

The first entry in their section on " Common Misconceptions on Oil Systems" (with the answer following the colon) is:

Oil pumps produce pressure: Oil pumps produce flow and the resistance to that flow produces pressure. The pressure relief valve limits the maximum pressure but does not do anything until the pressure has reached that point.

(Emphasis is mine...)

They did make one editorial mistake on that page.... see if you can spot it.

I see several mistakes. A lot of words left out an incomplete sentences.
In this statement I think they use the word new in place of the word old.

The valve or slots are there to allow cold thick oil into the pump. If you use thick oil with [new] screens, you a good chance of starving the engine of oil and ruining it.

They say that there is a varnish on the old .screen that is restricting the passage of oil into the tube. A new tube would not have that restriction.
Notice they left the word "have" out of the sentence making it seem like some idiot wrote it "you a good chance"

Now I understand the reason for the hole in the middle of the stock pickup screen.
Some good info but poorly written.
