I am using an AutoMeter Fuel Pressure Guage on my MiniRam injected motor, but cannot find an adapter that will allow me to screw the pressure sender onto the fuel rail-anyone out there know where to go for this? Thanks in advance!

 

i'm running an electric setup, i would assume the a/n should be the same size. unfortunately i do not know the actual dimensions but i did have to go to a special fitting store in my area for it and i had to use a step adapter.
