I have used 3 stock regulators.
I have used 3 different fuel gauges.
I have used 3 different b&m regulators

....Fuel pressue does not adjust! - Sits rich.
Anyone have a problem like this?
Any possible causes? - Clogged/pinched return line?

Thanks!

whats the stock pressure at idle and at wot?

 

what fuel pump you using?

idle 49-50 WOT goes down to like 40

 

Could be you need a new fuel pump ...

 

I thought fuel pressure was supposed to go up a little when on the throttle?

No we used two different ones.

You're absolutely correct...

 

Pressure goes up as a function of manifold pressure, not solely as a function of rpm. You could rev the engine at a standstill and the pressure wouldn't increase....it might even decrease.

 

when i rev, my manifold pressure drops (moves closer to zero) and my fuel pressure rises.

 

Hold it constant. The initial blip will increase the manifold pressure.
