Hey new to the forum looking for some advise.

In process of building a DIY 4.5 lpfp system include primary oem pump, secondary walbro 525, Aeromotive A1000 FPR.

As this diy system will be using a conventional fuel pressure regulator and an6 return line back to the tank do I just disconnect the oem fuel pressure regulator that is currently in the tank ?

I would upgrade the primary pump fwiw while you are in there. Relatively small money.

With the second pump you are bypassing the driver's side hat altogether?

The b58 engine / f20 chassis has brushless pump as primary.

Also it only has 1 hat which the filter and fpr are integrated

Excuse me, I thought this was in a different section.

There is not a lot of B58 content or users on this forum. Best of luck.
