I have (2) but selling seperately Accel fuel rail pressure gauges for the Ford 5.0 motor.
I bought them when I was working on a project on my 92' Mustang. One was used VERY little. The other is new. I ended up using a liquid filled gauge.
They apparently go for $70.00 a piece now at summit.

Both of mine do NOT have the brass fitting pictured in the pic but do come with the orig box and paperwork.
0-60psi
Asking $20.00 a piece shipped.
