Fuel press. gauge hook up question

[Dave 92Ty]

Where on the rail can I tap into? I see the test port on the drivers side, is that a AN style fitting?

It's 4AN with a Schraeder valve inside. Be careful removing the original cap, not to stip the threads on the fitting. A tire valve core removal tool can be used. I bought a nitrous kit fitting that has a 4AN outlet on top, which needs a cap, and an 1/8"NPT outlet on the side. I faced the 1/8"NPT side towards the driver's side valve cover and the Autometer remote sending unit almost rests on the valve cover. Others have different opinions on mounting the sending unit, like using braided hose and mounting over near the master cylinder. My way hasn't cracked the fuel line yet, and it's been on there for quite awhile. HTH,

Thanks, worked perfect. The Autometer kit # 3228 has all the right fittings.
