QuickGauge Fuel pressure Gauge.
As our beloved Cummins trucks age we are seeing more and more starting problems related to low fuel pressure. These problems can be very frustrating if you have no way to tell what's going on. Now you can install a quick gauge for temporary diagnosis or leave it on permanently. This silicone filled dampened (adjustable dampening) gauge fits right on the top of the fuel filter on 12 valve and early 24 valve Cummins engines in Dodge pickups. Just remove the existing banjo bolt (12 valve) or 1'8" plug (24 valve) in the top of the filter and replace with our stainless steel banjo bolt/snubber/Gauge & new washer combination (12 valve) or just the gauge (24 valve). That's it! Now if you have a starting problem you can quickly lift the hood and see if it's a fuel related problem or not. While cranking you should see at least 15psi. If not you have a fuel supply problem. This is the most important gauge there is when you are having problems diagnosing any diesel engine.
12Valve Gauge comes with new stainless/rubber bonded washers, pressure snubber and tapped banjo bolt.
