just wondering what fuel pressure gauge would work with the aem fuel rail. don't want another gauge to go on the fuel filter.. and what fittings would i need to screw that in? thanks! links to parts works for me too!

 

Any good quality liquid-filled gauge should work since they're all 1/8 NPT I believe. Most aftermarkt fuel rails have at least one 1/8 NPT port for a gauge. You really want to use a liquid-filled gauge since normal gauges like the B&M one will fail pretty quickly from the vibration. There's a Marshall gauge in the Sponsor's forum that works well and is pretty cheap.
