71 psi?

[DoubleDpsd]

Truck sat for 3 nights before I started it this morning. Started fine. Popped the hood just to take a look. Noticed the gauge on my ITP was at 71 psi. What's the deal with that?

nevermind... I think it's just because it was cold. I checked it right now and it bounces at 65psi.

Your truck started better than mine. Cold started mine today in 60* weather and cranked for 5 seconds then KA CHUG (loud start) then white smoke for a few seconds then a grinding noise for a second.

normal for it to bounce around 65-66psi when warm? That's where it was at after for driving around for an hour and beatin the piss out of it.

Are you looking at the liquid filled gauge under the hood (I'm guessing that you are)?

If YES, this is because the liquid filled gauges are sealed and significant changes in temperature affect how it reads...so it will read different COLD vs HOT.

You should not see this type of behavior with an electric in-cab gauge.

yea I was looking at the liquid filled gauge under the hood.

My electric incab gauge goes to 75 on startup and drops to 62 after a minute or two. It sits at 62 until the motor and fuel gets warmed up then drops to 54. My incab electric has always been 8-10 lbs lower (taken at the fuel filter housing port) than the liquid filled gauge on the underhood regulator.
