Please follow all steps in the order presented for best results and to insure personal safety.

Procedure:

1. Preparing the tank assembly.
First, we need to be sure the tank is completely empty and flushed out to eliminate any danger of fire or explosion.
Remove the valve core from the safety relief valve using the valve core removal tool, and allow all pressure to escape from the tank.

Then remove the valve core form the threaded fitting on top of the tank. You will have to first remove the plastic sleeve and the "O" ring from the fitting before the valve removal tool will fit into it.

Now flush the tank with compressed air until all traces of propane have been removed.

Using a hack saw or metal cutting blade on your miter saw, cut off the threaded fitting even with the body of the tank.

With a drill press and a 9\16 drill bit, open up the resulting hole to 9\16". Flip the tank over and drill a 5\16" hole in the center on the bottom.

Thread the large hole with the 3\8" NPT pipe tap. Thread the small hole with the 1\8" NPT pipe tap.

The drill shavings and other debris from these operations must be completely removed from inside the tank before proceeding. Use compressed air.

Now it's time to braze the 3\8" brass pipe nipple to the tank. Tread the nipple into the tank a few turns. Braze the nipple in place and braze shut the safety relief port at the same time. Allow to cool completely. Clean up your work with a wire wheel and examine the joint for integrity.

Next, thread the 1\8" NPT air tank fitting into the 5\16 hole in the other end of the tank a few turns. Remove the valve core from the fitting so it will not be damaged when soldering the fitting in place. Use some soldering paste and a good grade of electrical solder and heat the area with a propane torch. Flow solder around the fitting. Allow to cool completely.

When cool, replace the valve core in the air tank fitting. Thread the 3\8" NPT pipe cap onto the 3\8" pipe nipple to seal the tank assembly.  Pump up the tank to about 50 psi. Spray Windex or soapy water on the braze and solder joints and watch for bubbles. If any leaks are detected, re-braze or re-solder as necessary until you have a perfect, leak proof seal. Paint the tank when finished.
 

Thread the 3\8" 90 degree brass elbow onto the 3\8" brass nipple you brazed to the tank. Use Teflon thread sealant. Work carefully to avoid getting any Teflon tape fragments inside the piping.

Thread the 2" X 3\8" brass pipe nipple onto the 90 degree elbow. Thread the solenoid valve "IN" port onto the 2" X 3\8" pipe nipple. Thread 1 3\8"NPT X 1\2"SAE fitting into the "OUT port on the solenoid valve.

This completes the tank and valve assembly. Check for leaks as described above. Now it's time to wire the system.

Solder a 1\4" female spade connector on each of the wires coming from the coil of the solenoid valve. There are two red wires and one green wire.

On one red wire (it doesn't matter which one) connect the in-line 2 amp fuse holder assembly to the 1\4" spade connector also.

Connect the red wire with the in-line fuse holder to terminal 3 on the control module. Connect the other red wire to terminal 1 on the control module. Connect the green wire to terminal 2 on the control module.  Connect the 120,000 ohm resistor between terminals 4 and 5 on the control module. The resistor should be removable so don't solder it in place. Use spade connectors.  Now connect a length of 16 gauge primary wire to the free end of the in-line fuse holder.

This completes the system wiring. Now lets check out the system for proper operation.

Check Out Procedure:

Pump up the tank assembly to about 50 psi. Carry the pressurized unit to the vehicle. Touch the solenoid valve body to the negative terminal of the vehicle's battery.  Touch the end of the primary wire to the positive battery terminal.

 *** IMPORTANT - BE CAREFUL ***

A strong blast of air will issue from the "OUT" port of the solenoid valve if the wiring has been done correctly. Direct the "OUT port away from your face or anything else a blast of compressed air could damage.

The air blast will come instantly as you touch the primary wire to the battery terminal so be prepared for it. You will need to continue to hold the connections in place for about 15 seconds to determine if the prelube cycle is functioning correctly. (If you interrupt the power to the unit during the prelube cycle, the module will re-set and you will have to start over.) In about 10 to 13 seconds after the air blast from the unit, you will hear a dull thud as the control module cuts off power to the valve and it closes. Listen for it. Repeat this procedure until you're sure the system is operating properly. This completes construction and testing of the tank and valve assembly. You may mount the control module on the tank as shown in the photos on our web site or mount it where ever convenient.

Now it's time to install the system in your vehicle, connect the primary to the vehicle ignition system, fabricate and install the hydraulic line.
Installation:
Choose your mounting location carefully. It should be mounted with the tank vertical, as close to the oil pressure sending switch port on the engine as possible, (This is where you will be making the hydraulic connection.) and away from hot exhaust manifolds and pipes.

Once the unit has been mounted, remove the oil pressure transmitter switch from the engine block. Determine the thread size of the port and obtain a brass or steel pipe nipple of the same size. A close nipple is best but a longer nipple can be used to stand it away from the engine block if clearance is a problem. Attach the 3\8" brass "T" fitting to the nipple. You may need a brass reducing bushing if the oil pressure transmitter switch port is smaller or larger than the 3\8" brass "T" fitting.

Re-install your oil pressure transmitter switch in one of the openings of the brass "T" fitting. Install a 3\8" NPT X 1\2" SAE brass fitting in the other opening.

Now it's time to make up the hydraulic line. Carefully measure the distance between the prelube unit and the "T" fitting on the engine block. Cut the proper length of AeroQuip hydraulic line and attach the end fittings as per the instructions that came with the fittings or take the components to your AeroQuip dealer had have them make up the line for you. It is extremely important to assemble the hydraulic line correctly as a leak could result in engine failure. Connect the line between the prelube unit and the "T" fitting and you're finished with the installation.
Operation:
Once you're satisfied the unit is installed correctly, pre-boost the tank to about 20 psi with the 12 volt air compressor. Now start the engine and let it idle for a few minutes. Now is the time to check for oil leaks. Carefully examine ALL the connections you have made and be certain there are no leaks. Stop the engine and check the oil level. It should be about 1 quart low as the engine has pumped about that much into the tank assembly. Add oil to bring the level up to the "FULL" mark.
Checking Out The System:
Turn on the vehicle's ignition switch but DO NOT start the engine. The oil pressure light should go out instantly and stay off for 10 to 13 seconds. If the vehicle is equipped with a gauge, it should show a reading of about  3\4 of the vehicle's normal operating pressure for 10 to 13 seconds.
Other Notes:
Fuel injection vehicles. Some fuel injected vehicles have an on-board computer that will not allow the ignition to remain on for more than about 4 seconds unless the engine is started. This can result in a very short prelube cycle if the unit is connected to the vehicle
ignition system. In this case, look for an unused connector on the vehicle's wire harness that shows 12 volts with the ignition in the ON or START positions. Make sure the connector you choose continues to deliver 12 volts so long as the ignition remains in the ON position.
