Questions: What is the difference between this and the heavy duty valve?
Question By: Smith on Jan 23 2020 11:07 PM
The heavy duty is a bit thicker walls and valve. But both work great.

Questions: Does this piece attach at the water pump? I guess i have an aftermarket water pump on a CJ-3A L-314 with 2 valves, one going to the non existent heater unit which needs to be plugged.

This typically goes on the head itself.

Questions: I see you have the manual shut off valve for the heater. Do you have the shut off valve that mounts on the firewall and is controlled by an inside cable. This is on a 1957 sw,L6-226 ?

This part is the manual shut off used on the head. Any others would be used only. This could be used in a number of places however with the right fittings.
