If you are installing an Auto Meter electric fuel pressure gauge in your Dodge Cummins Diesel truck, you MUST install this #3227 braided stainless steel line kit and #3279 (sold separately) fuel pressure snubber to prevent premature failure of the sending unit. Failure to do so will void the gauge warranty.
Kit includes:
3ft. of #4 braided stainless steel line
firewall pass through grommet
1/8" NPT female right angle to -4AN male fitting
-4AN male to 1/8" NPT male fitting
-4AN male to 1/8" NPT female fitting
1/8" NPT to 1/4" NPT adapter bushing
Recommended for use with all fuel pressure gauges.
