seems these came from golf carts and burned too fast.

Train coils can be had when a train has wrecked, just walk over and pull a pair from the ground.

Problem is, these are no good for a cars suspension. Unless you want to brag and use accumulators.  The ride is extremely hard.

One way to wire up your switches is to have the three switches and the one for the release is in the center of your switches, or just hang it to one side or use a different color/wire switch.  To avoid getting mixing up the switch or direction of the switch handle, wire the switch so that power goes out each output terminal.

One the quick disconnect switch, you don't need to figure out which way to move the handle, just move it in any direction

[UPDATED 11-1-2015]

UPDATED 11-1-2015


I now have another BMH piston pump, and another idea on how to control the high pressure nitro gas. It makes it more simple.

And I now have 3 Adex dumps to insure correct action to purge any left over gas and also as a added safety devise/s.

The big Green is still an option, but, I'll need to buy one or two if the 3-ways don't work.

It is my belief that I do not need Adex valves, Adels would be better, as I believe I need sloppy valves for the gas pressure. I also have four NOS aerospace #8 valves that might be used. Remember, Adel and Adex perform well as they close very fast.  I don't need that with gas.

next up and good look at the block and the use of all it's ports.

Looking at block from the pump head side, we can see two holes drilled in at about 5 and 7 o'clock.  These ports are made so you can position your return plumbing on the left or right side. These ports are also used when building a double pump setup. The return port from one block can be connected to the return port of the other block. So it's like have a whammy tank to equalize the fluid levels in both tanks.

Now there is something very special about these return ports, is that they can be used as pressure ports. It's when you pump a huge amount of gas pressure on the gas side of the piston that can cause the car to raise. Not only will the gas pressure cause the return ports to force fluid to the cylinders, the fluid pressure is also forced past the gears and check valve.

If you hit the switch, you'll also have the gears adding additional pressure to lift the car.

You can't keep all this pressure in the tank as the car will never dump, the gas pressure that is lifting the car must be expelled.

[Believe is or not, the first pic is most likely the most amazing pic you have ever seen of any gate pump, It's a one of a kind that you will never see in a car show.]

why it's so small I don't know, try to blow it up to see the real engineering involved in making this pump work.

Here is how the tank looked after 10x as strong threaded bolts were added. They has a tinsel strength of 17,000 pounds or PSI (?)  Got them from Grainger.

The backing plate was made from a steel pro-hopper backing plate. Note the ghetto drilling of the hole for the hoses.  

You may not be able to see them, but the old threaded sleeve were never removed, just rotate the tank.

The top two pics show the fittings for the high pressure gas hoses. I had to have a machine ship do that work.  Because of transporting and fluid management, shut offs had to be installed at what was the original return fluid ports located at the block.

The next to last pic shows the schrader valve has been replaced with a plug and we have jumped ahead to show the intake and exhaust hoses.

This is ready to bolt on and test, during tests, one of the hold down screw bodies broke loose and another cracked. This may have happened at around 800 PSI

NEXT UP, DEFECTS WITH TANK

Here's the problem, that welding screw bodies actually has two different size holes tapped. One side has bolts coming through the block and into the thread body.  The other side of the thread body is made to look like the hold down rods and backing plate are real. There are not even needed, it's to fool people into thinking is was a regular gate pump.
So the thread were too short as well as the welds were weak.
