should be a port on the fuel rail or general vicinity to hook a pressure gauge up to, another thing to do is get some gauges for your truck, fuel pressure, boost, egt, trans temp. so you can keep an eye on everything while driving, and since it's an rv puller, i would suggest getting them soon. or maybe the edge juice w/attitude since it has all the gauges on the in cab monitor.
