I have a 1977 coach that doesn't seem to have the boost pump or the switch, so I suspect that it didn't come equipped with the pump. Are my suspicions accurate? The heater doesn't keep up with the cold despite all the values being in the right position. I get heat, just not enough. How much work would it be to add the pump?
