So after searching for what seems like forever, I've found this Metco adapter that will allow me to hook up my 1/8 NPT fuel pressure gauge sender to the -4 AN fuel rail. Lots of info on this in the search area.

However, in the threads I've seen no one really mentions how they intend to relieve the fuel pressure in the rails later since there is no Schrader valve/test port anymore. Has anyone devised a way to installed a 1/8 NPT sender to the rail but still keep a test port? Some sort of tee with a schrader in it would work, but I can't find that.

Barring that, how do you relieve pressure after installing the sender?

Here's the Metco piece I found - http://www.metcomotorsports.com/prod...p?prod=MFF0001

Really no need to relieve the pressure.

I change injectors & never even use the schrader port.

Pull the fuel pump relay or fuse and crank the motor.

Thanks, gents. That's simple enough. I suppose that's why no one had asked in the threads I found
