Hey I have an odd dilemma.
I have an aftermarket, adjustable FPR running inline with my stock FPR (still attached to the secondary rail). My problem is I noticed that my stock FPR leaks out the vacuum port. I had it disconnected when running and it just continually drips fuel.

I assume this should not happen...
My question is does anyone know what kind of fitting to use or how to eliminate the stock FPR? (I'm not talking all new lines) I'm just looking for a way to eliminate this faulty FPR and just run my aftermarket one.

You need to ditch the Stock FPR and run just the new FPR.
above is some info and a place where you can get an aftermarket rail if you run S5...S4 TII rails can accept a fitting as S5 rail have a built in FPR.

Thanks, will eventually do that. I believe I have an s4 rail, as the fpr is removable. I tried to find a fitting to delete the fpr but was unable to locate the proper thread pitch. Any idea what the thread pitch is on the s4 fuel rail?

I did this system a long time ago.
Now if you just do the FPR delete,then all you need is that fitting to a Barb.Take off the old FPR,install the fitting,put the hose to the New FPR and you are done.
