View Full Version : External Fuel Pressure Guages

I'm looking to install an oil-filled fuel pressure guage at the end of my fuel rail on my 86 GN. Can someone suggest where to buy these at a reasonable price? Also, do I need to relieve the fuel pressure in the line before installing this? thx in advance for all the great advice!

Autometer makes a kit, as does VDO and several others. Jeg's/Summit all carry them.

If you are looking for the little end of the rail jobbies, try Casper's, Poston's, Cotton's, etc. Most sell them.

Most definitely you should relieve the pressure in the rail. Some of the gauges will engage the schrader valve (and can spray fuel all over) ... other will require you to remove the valve.
