Got all of my XRP port fittings welded onto the water pump and thermostat housing. I obviously hacked off the -16 threaded male from the thermostat housing to make room for the XRP clamshell port. Then the two -8 ports for the heater hoses.
Upper port welded on and mocked up with a 90 degree -16 clamshell fitting.
I also came up with a bulkhead design for the heater line connection at the firewall. 1/2″ aluminum plate with a -8 straight cut threaded center. Then a 5/8″ round tube welded to the back side. This tube will actually get cut down quite a bit. It will then attach to the plastic tube coming off the heater box on the inside of the vehicle via a rubber hose. I will also need to cut down the plastic tubes as far as I can to squeeze it all in there. I still need to thread the outside of the 5/8″ tube. I will use a large washer and nut threaded onto it to sandwich the bulkhead to the firewall. Lastly I will powder coat the bulkheads black.
With 90 degree XRP -8 clamshell fittings:
Mocked up in the car. Note: I may not use the 90 degree ports… I also have 45 degree ports, straight ports etc. to tryout and see which is going to work best with the motor in there. I just tossed them on there for picture sake.
