The truck has 232000 not sure of any replacements of anything. Was told thing were acouple years old but not true. So NO idea. I put a gauge on the schrader valve and going down the road and have about 4 psi give or take. At idle it has a bounces about a quarter pound. Should I replace the mechanical or put on electric? What psi should go to the IP?
