Hi everyone, I'm sorry if this has already been adressed about I apparently can't find the post so bare with me, I am wanting to install a fuel pressure gauge on my 1991 cummins, what is the safest and convient way to do so? Any one with a step by step write up? Thank you in advance

 

Easiest way to install is to replace the banjo bolt on the outlet of the fuel filter with a tapped bolt from Geno's Garage. One listed for a 2nd gen will work.

 

Ok, recommend electric or mechanical gauge?

 

Not the recommended way, mine is run thru a shut off valve directly to a mechanical gauge. I'm not too concerned with fuel in cab.
