GOOG Posted January 2, 2016 Share Posted January 2, 2016 Does anybody use a fuel pressure gauge in their dash? My Superliner has one. The guy that bought it new had it installed by the dealer. He is well known for specing and keeping a truck well. I think it's info worth having.

Kansas farmer Posted January 2, 2016 Share Posted January 2, 2016 I have one in our Pete. I like it. The quality of the fuel these days is horrible. I can tell when the filter is starting to get plugged and I can change it. I would like to put one in our ch also.

Timmyb Posted January 2, 2016 Share Posted January 2, 2016 I have a fuel restraint gauge in my kw. Has a line running from the fuel/water primary filter. I can't understand it...

GOOG Posted January 3, 2016 Author Share Posted January 3, 2016 I'm sorry, I just saw the KW part. I never heard of fuel restraint. Quote Link to comment https://www.bigmacktrucks.com/topic/43353-fuel-pressure-gauge/#findComment-318491 Share on other sites More sharing options...
Timmyb Posted January 4, 2016 Share Posted January 4, 2016 Yeah, it's before the transfer pump and works on vacuum. Any blocked filters or lines and hopefully this gauge will let me know about it. It has an air restraint gauge too. I haven't seen either of them move since I've been in the truck.

Should be running to a tapped port on the air intake between the air filter and the turbo.
