1972 Duster Build with my Daughter
Day of details. Got all the underhood wiring done as well has heater hoses and AC hoses. Installed the new AC dryer and what the hell lets go for broke and pump her down!
35 year old RobinAir vacuum pump still going strong...
All the AC clamps restored and installed.
Sucking it down!
The low pressure switch is in the AC dryer. A 1972 the dryer is right there on the inner fender, the '73 AC system I installed the dryer is behind the grill so I had to extend the wires.
This is a GM valve that is 5/8". The original was 1/2" but NOS is $250, I can't see that. I plumbed a 5/8" nipple in the Edelbrock and ran it over here and out. I then added a reducer to 1/2" to go into the heater core.
5/8" to 1/2" reducer inline for the core.
Extended wires to the low pressure cut off switch.
Here is the dryer and cutoff switch.
