If you want rail pressure only, PPE and others have gage kits: http://www.pacificp.com/store/index...id=197&zenid=8d09b271057a7f03f4d22fe4087df457

If you wanted to see if a lift pump was working you could put that tap on either side of the filter (downstream of the fuel filter will give you some indication of your filter getting packed off).

If you have EFILive, you could just log it.

Aeroforce uses the ODB2 port to indicate pressure using the sensors already on the engine and with one of those, you can monitor desired versus actual pressures in a single gauge. http://www.aeroforcetech.com/products_interceptor.html These will also allow 2 analog inputs per gauge, one of which could be the EGT.

I would use an electronic gauge regardless of application so you did not have fuel on the cab side of the firewall.

If you do not already have an EGT, the Aeroforce is a good way to go for being able to see a lot of parameters with one gauge (it has 2 digital displays per gauge). They are not really cheap, but pretty handy (I have a dual set). If you use the analog inputs, you can also wire them into the analog inputs on EFI. The down side is that the Aeroforce must be unplugged to use EFI for logging.

I use an analog input (Aeroforce electronic pressure transmitter) for the fuel pressure and run the output wire to my Aeroforce and the analog input to the V2. There is no PID for fuel pressure into the CP3.
