Fuel pressure

Is there a specific fuel pressure gauge that I can use for my 411?

The reason I ask is that on the steel part of the fuel loop, on the left (driver's) side, I looks like there is a threaded port to attach such a gauge. Mine is blocked with a small bolt. This appears to be about a 4 or 5 mm orifice.

Thanks, guys.

Remove the bolt and slip a 5/16 (7-8mm) hose over the outside of the steel nipple.
