ask Whip618 if he has any blueprinted ones for sale. Don't go back down the type 1 pump in a type 4 engine route again. That is what the last person tried.

Sure the tang on your new pump is engaging in the slot in the cam?

Get a Coleman funnel from Walmart, it will be in the camping section and the funnel should have a screen in the bottom of it. Using a bit of hose and a 1/8" pipe fitting from a hardware store, rig up a way to hook the funnel up to the oil pressure sender port. Now pour at least a quarter quart of oil into the funnel filling the oil galleys. Use something like a 0w30 oil so it will flow easily. Now crank the engine and see if it will blow the oil back out.

If you still don't make oil pressure remove the mount for the oil filter and see if the valve is still inside the mount, maybe it came apart and is causing a clog in the system. Yes this is a long shot.

if you did not prime the pump with oil, it is not going to pick up anything. It will spin forever without pulling oil. You only have to learn that once in your life.

Be 100% sure you put it in so the oil ports aligned with the case. The tangs on the pump should be horizontal when viewed from the outside, and the protrusion at the bottom.

as long as oil gets down to the oil pump it will pull from the sump. Do make sure that in all this fuss you didn't drain the oil and forget to put some back in. Really.

The clearances in the pump need a film to work with,
Vaseline was the recommendation years ago, but your oil of choice
or even a little gear lube will do the trick.
But a dry pump isn't a pump. Coat or spray or funnel something down there
to get it to draw.

Well i put in 300 ml of oil via my intravenous setup and cranked it over and on second crank over it built up 22 psi on gauge!!!!
Needless to say I was very excited and much appreciated the help I received from this post! Now to finish putting her back together.

Let's recap

Bus drives fine
park it overnight
Start up = no oil pressure
You try everything you can
Finally change pump
Start up = no oil pressure
Going in circles

Something got missed and it's not priming the pump
