fuel pressure gauges

hey, i got an aftermarket regulator and realized i need an underhood gauge to make tuning easier. i'm looking at the ones summit has to offer and dont' wanna pay 60 bucks for the accel and bbk ones made specifically for 5.0 EFI mustangs. question is, do any of you run the summit ones, and what if any adapters do i have to buy to make it fit the male NPT port on the feed line near the alternator?

Get one, and save your cash.
