high pressure oil pump?

so i just took my truck in after about a month or so of it leaking oil on my 2nd gen 7.3 and i found out that it was my oil pump, so a new STOCK one is like around 800... but what are the pros and cons of a high pressure oil pump?

Not sure I understand what you're asking.

The HPOP is the pump that puts oil at an increased pressure to the injectors so they will work correctly to inject diesel fuel into the cylinders. Definitely a PRO....

Cons? They leak...sometimes?

Is this the oil pump in the bottom of the engine in the pan -OR- is this the standard HPOP that I described above?

The one in the pan circulates oil in the engine and feeds the HPOP so it can do it's job.

just send it in to Joey@ Terminator and have him change the seal and mod it for higher psi for 100. bucks can beat the price.

I think you are a bit confused. These trucks have 2 oil pumps. There is the low pressure pump that supplies lube to the engine, and also oil to the high pressure reservoir. The high pressure oil pump is what supplies oil to the injectors to fire them.
