So my air tanks drop pressure after the truck sits for a while so I once again used Cal Blue to check all air lines & fittings . Found a leak at the air feed to the manifold,replaced the line & all is good. At the same time I had the truck aired all the way up & sitting noticed the rear drivers side would drop, so I pulled that bag & tested in a bucket of water, & found it to have a leak. These have been on my truck for 16 years, & like tires should be changed out at 7 years ! 2 new Firestone 9000 bags will be here Monday,
After 16 yr it makes total sense. Wishful thinking makes us believe things will last forever! Haha if only..
