i just put in pyro and boost gauges about three weeks ago and the last couple of days i've noticed the boost gauge rattle when i'm excellerating. i've checked all of the connections and there good. has anyone else had this happen? if so how did you fix it? thanks

 

My Isspro boost gauge rattles also at about 20 and above lbs. Don't know why. I'm living with it, though.

yeah thats about what i was going to do unless someone had answers. thanks though.

 

http://www.dieselmanor.com/dm_products/fittings.asp It's the one called a Pressure Guage Stabilizer, also known as a "snubber". I had to put one on my boost gauge too.

 

There is a small orifice in the Isspro gauges that sometimes comes loose. If you pull the fitting off of the gauge you should see a small slotted orifice threaded into the gauge port. Might be loose. I have to look at mine soon, got this tip from another DTR dude.

 

Wow, thanks Michael! I will check it out.
