How to check fuel pressure?

[Catterman]

I have a fuel injection pressure testing gauge, but for the life of me I can't find the location to hood it up to. I even tried searching Youtube, Google, and this site and no luck. Anyone have a picture of where that connection is made?

Sorry, I don't have a pic. But if you look on the passenger side, beside the aluminum intake, there will be a metal fuel rail. About 1/2 way is what looks like a air valve, like what you would use for inflating tires. It should have a cap. It may be easier to follow a fuel line from the other side of the engine, as there is a bunch of wires and cables in the same area.
Maybe someone else will have a pic.
Good luck,

Richard

Okay, I will look again. But you are saying it is on the Passenger side, kinda in the middle top correct?
Thanks!

It should have a black cap(like a tire air valve cap) on it.
