Alright guys, anybody have this problem? Just put on an Isspro pressure guage with the Diesel Manor daiphragm isolator sourced to the bottom of the filter canister. I can't hear this new squeak at idle, but while driving I can hear it. It changes intensity and frequency with rpm and seems to be coming from right where I mounted the isolator. I haven't yet got the hose to the guage bled properly , as the dash portion of the install is not yet done. I don't think that is the cause of the sound. I used all of the Diesel Manor hose and fittings and isolator. Any thoughts or ideas? Thanks in advance.
