Fuel Pressure Gauge Installation Question

[RockinJ]

I'm taking delivery on a new 2500 with the 325/610 engine. While monitoring transfer pump pressure is not critical on an HPCR Cummins, I want to install a fuel pressure gauge anyway. Where is the best place to tap into the fuel system?



BTW, please ignore my signature . . . I need to update it for the new truck.

I think a clean way would be to replace the standard banjo bolt on the bottom of the fuel filter housing with one that has a standard pipe thread outlet on the end, from there screw in an electrical transducer for the gauge such as a SPA.

I ran mine straight off the CP3 pump; the SRT/10 mount is nice, too. Here's a couple of pics for you.

Matt,



Thanks for the info. BTW, what kind of fuel pressure are you seeing at idle, cruise and WOT?

what kind of fuel pressure are you seeing at idle, cruise and WOT?

• idle= 9. 0 psi
  
• cruise= 7. 0 to 8. 0 psi
  
• WOT in the 5 psi range
  

Thats with the box turned off or on a lower setting. Turning up the power will draw it lower.

Those are pressures with a clean filter, scotty banjo delete and 1/2" filter to CP3 line. At this time I am still on my factory filter mounted lift pump.
