Adjustable Fuel pressure Regulator

[3400-95-Modified]

Ok, I have an original "Caspers" adjustable fuel pressure regulator, Something has recently started to go wrong with it.. I can't dial in the pressure to what I want.

At one point the peak will be 55, if I touch the adjuster not even a 1/16 of a turn it will be up to 65-67 PSI. I used to be able to hold a solid 63 very easily and have broad adjustment with that screw but now I've got nearly nothing for adjustment where I want it.

SO the question is... Can this be re-built? does anyone know? And if not does anyone sell an adjustable one that fits our rail anymore? Or should I be moving to a different style?

I'm guessing just about anything from TCE is going to be on hold due to his health concerns right now so I don't think ordering anything from his website is an option.

Isn't it just a stock regulator that has been cut open to have an adjustable top added? I can't see why that can't be moved over to a new regulator.

I've modified a couple stock regulators myself to be adjustable.

That's what I was hoping to hear for an answer I just wasn't sure though.

I'll have to tear into it and see how it's made and see if i can replace it with another bottom.
