Ho many people with LT1s are using them? and how many defective ones have people run accross??

I am pretty sure that mine is defective because when trying t o adjust the FP the gauge stays pegged and dosent move off of 82-83psi even when the screw was on the lowest press setting.

 

That's really wierd. I have to tighten mine to get the pressure to go up, are you going the right way?

Mine may or may not be defective, my pressure drops when the pump isn't running, but I haven't looked into it enough to blame the regulator.

 

I have a brand new Walbro 255lph pump and it definetly supplies the fuel and on the reg I tried turning the screw both ways to the max with out even getting the slightest change in pressure( counter clock wise to releve press) and clock wise to build more pressure.
So I am doing it right its just that the regulator doesnt seem to be doing its job.

 

What kind of gauge are you using. Could it possibly be the gauge? I had a fuel pressure gauge stick at 20psi before.

 

stay away from those pieces of crap worst reg ever.
