fuel pressure gauge with flex lines?

Hey all...

I'm replacing my hard steel chrome fuel lines from the frame rail to the fuel rail with a Russell pre-fab kit. The original lines on my 87 GT are rusted and generally just in bad shape. I also went to ARP head bolts and there's no stud at the front RH corner for supporting the steel lines, keeping them from rubbing on everything.

Any ideas on where to put my fuel pressure gauge since I'll be losing the pressure port? I have a 20 yr old Paxton FPR that has worked fine, but I'm willing to replace it if there's another out there that has the gauge pressure port on it.

OK, Now I did some research and see most FPR's have a 1/4" NPT port for a pressure gauge. My old Paxton FPR has an unused plug in it below the vac port... is that most likely for a gauge? Can't even find any info on this old Paxton FPR...

Thanks man. Got it all figured now. Jumped the gun on the post. On my way for a 1/4 to 3/8 NPT adapter...
