Have a Craftsman Model 106.152581 that I purchased new in the mid to late 70's. For sometime when I want to use it I have to shut on and off with switch on pressure switch. Will pump up fine but not shut off once it reaches 100 psi. If I do not shut off it will pump until safety valve activates and releases air pressure. Many years ago I had to replace the pressure switch when it done this. Part at that time was available from Sears. Part # CW-2075-23 is now obsolete and not available. Also called CH who made unit for Sears and they had nothing. Looks like my options at this point is to purchase a switch that meets the 80 on 100 psi off parameters and try to adapt to my unit. Is this a reasonable route to go?

Looking at the kit you are recommending it looks like it is a 95-125 psi pressure switch. As stated above my unit is a 80 - 100psi unit. What do I need to do to use the kit you are recommending?
