where do you 12 valve guys have the fuel pressure at?? right on the pump??

 

At the banjo bolt that goes from the lift pump to the injection pump. Drill and tap it.

 

And put a needle valve of pressure snubber on it.

 

Tapped injection pump banjo with needle valve installed

 

Do these come with a guage kit or do i buy the guage and line and then have to buy one of these

 

There is no "gage kit". You will need to buy the parts individually and install them. You can do this for less than 25.00. I used a 0-60 psi gage, giving me a good sweep, a needle valve from a good hardware store and can't-remember-which-tubing, but it was cheap. You will need to drill and tap the banjo bolt to thread in the needle valve, and you MUST have the valve or you will ruin the gage in no-time.

 

Ok thanks for the help
