Fueling & Injection - How to fix to much fuel pressure?

Still got a bit of an issue with my 99 Trans Am.
I'm running a racetronix fuel pump and hot wire kit.
Car started to run funny and now I'm seeing 68-70 psi at the rail
so I think my regulators stuck open or is there any other causes for high pressure?
Car has H/C all bolt ons and is tuned for the 42lb injectors and stock psi.

I'm wondering what to do now, I have to buy a whole new fuel assembly for a stock regulator right? Or can I get away with putting a returnless aftermarket regulator at the rails, I really don't want to drop that tank again :( and if I'm going to spend tons of money on stock parts I would rather upgrade :D.

So what should my plan be.
Any help is always appreciated, JR

If you have a return style system, put an in-line regulator AFTER the rail in the return line and you should be all set.

You might be able to find a used sender and steal the regulator out. But you may end up with the same situation (have seen it before). Give me a call I can also set you up with a return setup that could help.
