Here you will see the mixer assembly bolted on the factory carb base. You’ll notice we reused the factory carb base for its unique throttle and pcv mounting. You will need to reuse the the (3) factory screws that bolt the base to the adapter.
When you mount the mixer and regulator, this is how it'll look installed in the truck. The regulator needs to be securely mounted. The hose in between is flexible. Be sure to check that all fittings have Teflon tape on them and are tight.
At this point, you can see the bottom of the regulator. Notice how the line goes into the filter, the solenoid, and the regulator. The solenoid gets wired to a key on 12v at a very low amperage.
Next, the water lines must be spliced into using the "Y" connector. The direction of the "Y" fittings is important. If you do not run a heater, connect both hoses to the regulator without the "Y" fittings. If you look carefully the straight part of the "Y" goes inline with the heater hoses. Both "Y's" will have the same angle. The other one in this picture is behind the first. Make sure they're not backwards because coolant will not flow properly and will cause problems. The front line is the feed and the rear is the return.
Here we show the hoses connected and the kit installed. Notice the vacuum advance is connected to the forward port on the distributor. This port is the advance. The other end connects to a ported vacuum source on the carb base.
Pictured is the correct installation of the tank brackets, which are adjustable by turning the hold downs. The brackets must be mounted to the truck with grade eight bolts and washers. Also needed are large washers under the bottom of the truck to prevent the tank from pulling through the floor.
The bulkhead fitting back by the tank has a pressure relief device built into it. It is very important that all connections are tight and checked under pressure with soapy water. This is where the line connects in the back. The propane line must be kept at least a foot away of the exhaust and be secured every 8 inches. We highly recommend following the factory steel fuel lines.
This is how we recommend connecting the tank to the bulkhead fitting. Once you fill the tank and start the engine, check for leaks, and set the idle mixture by turning the screw on the side of the mixer. These adjustments should only be done with the engine warmed up. To set timing, drive the vehicle and keep advancing the distributor until you hear it “pinging” or detonating, or until it doesn’t make any more power. Back it off until the pinging stops. You may have to perform this procedure several times. The idle mixture as well as the high speed mixture adjustments have already been pre set. Turning the big screw out leans the idle mixture. Underneath the mixer where the black elbow screws in is the high speed adjustment . There is a “R” and “L” to tell you which way to go.
After you have inspected everything, you're ready to hit the trails. If you have any questions, please call Cary, (480) 430-8033.
