OK you Diesel Gear Heads, I got a question for you all. Does anyone run a fuel pressure gauge in cab, and if so what are your pressure readings under load? My gauge runs 20/22 at cruise, and down to 8 when under hard acceleration. My filter is new, and my pressure is within spec 22 at idle and 30 on a throttle snap test. I was just curious what the pressure should regulate at under load.
