90 Civic PGM-FI: Best Place to Check Fuel Sys Pressure?

Where is best location to check fuel system pressure on 90 Civic PGM-FI (SOHC)? Any suggestions most appreciated.

on the fuel rail there is a fuel pressure relief bolt and hook up there

Thanks for the response. This system is dual-point throttle body injected, so "fuel rail" may not be relavant here. I only see banjo fittings at all engine compartment connections. I could make up a custom pressure tap at one of the banjo fittings, but this would be a project that maybe could be avoided, if one knows where Honda intended the fuel system pressure to be measured and using what fittings. I obviously don't.
Thx - Ed

you could check and measure fuel pressure on top of the fuel filter using b&m fuel pressure guage.

Wiseguy01 & Ones&zeros,
Thanks for replies. I found the key tap point at the outlet connection from the filter (banjo bolt has tap hole). I was hidden under some hoses & I missed it.
Thanks - Ed
