Another Gauge Question

[donnier]

Im in the process of adding gauges to my stock 05 and was curious which would be better. A fuel pressure or rail pressure gauge or are they for the same thing?

Thanks.

Fuel pressure gauge measures fuel coming into the cp3. A rail psi gauge measures the pressure inside the common rail. If you are staying stock. I think just a fuel psi gauge will do fine. If you plan on doing mods to your truck you might want to pickup a rail psi gauge, but for the time being, I think a fuel psi will do you fine.

Fuel pressure <50PSI, rail pressure can be up to 23,000 PSI or more. Big difference.
