Procedure:
1) Perform the standard pump relocation mod by removing the pump, wrapping it in
tape, and gluing it to the side of the gun.
2) Saw off the housing that used to hold the pump except for the section directly
below the clip.
3) Detach an SM 750 air tank from its pump and glue a 1' long segment of flexible
tubing between the two. *Note: Do not use aquarium tubing. It is not strong enough to hold the pressure.
Use flexible tubing froma hardware store. I learned that the hard way. :-(
4) Attach a 6" long, 1/2" CPVC barrel or brass barrel (9/16" or 17/32" diameter).
5) Wrap the SM 750 tank in pipe insulator or a thick layer of tape and insert it
into the pump housing that is right below the clip. It should fit snugly due to the layer of pipe insulator.
6) Secure the SM 750 pump onto the side opposite the PC's pump.
Sadly, mine broke shortly after its completion due to a leak in the aquarium tubing.
The gun worked great during testing though! Have fun and be careful!
