I have an aoutometer fuelpressure gauge. It's electrical and came with a sending unit. Where does it go? There is a valve in the fuel rail where I assumed it would go but they both have male ends with no adapter.

 

You'll have to buy an adapter to hook it to the schrader valve. Once you do get one make sure you take the valve out before you put the adapter on.

 

dumb question, is that the one on the back of the fuel rail?

 

Use a tire valve stem removal tool and take the valve out of the rail. Then tighten up fittings and go.

 

Alright, thanks for the info fellas.
