CHIEFWAHO Posted October 21, 2015 Report Share Posted October 21, 2015 I have an air leak at the dash pressure gauge (front). These appear to have the same style of hose push connections as the other fittings on the truck. I gently tried to remove the collet to see about replacing the o-rings as I have done on other fittings. The collet does not want to come out. Before I get to rough with it, does anyone have experience with this? Hope the o-rings and collets are replaceable. Priced a new single gauge and it is $162 before shipping and tax. Located in the left side of this picture. They are color coded red, green and black. 1999 Volvo VNL610, Cummins M11 - 350/400 HP, 10 speed Rockwell - 'CHIEF' Custom flatbed with TrailerSaver air hitch. 3 cyl 8000 watt Kubota diesel generator.
