Fuel pressure gauge

[89-LX]

Having a fuel issue with the Mustang, and I need to find a fuel pressure gauge to run some tests. Not looking for a hand held one that goes on the schrader valve, as I need to test it under load. Just wondering if anyone had a cheap one laying around that I could scoop up? Want to replace a few fuel lines to see if they may be pinched, or work on some wiring that could cause the fuel pressure to drop from 39 to 25 PSI at like 4800 RPM's.

I have seen some techs use the hand held and route it up to the windshield for road tests if that would work out for you, HF has them pretty cheap too.

I've got a Summit liquid filled 0-100 lb laying here. Like one you would mount on a carb inlet line 1/8 npt rear mount.
I think these cost like $20.
