Still waiting on the AN6 fittings for the 4 liter aluminum supply tank. Once that is done, I'll fire it up and see how it works. I've hooked up everything electrically and also mechanically except for the connections to the tank. Its been about 3 weeks since I ordered the parts so those fittings should be here any day now.
I am also installing a vent/drain valve at the inlet of the filter/dryer so that I can drain any condensate that ends up at the input to the filter housing, even though I am keeping the inlet of the housing above the outlet of the compressor discharge valve body. Oh, and I also grounded the system (installed a ground wire from inside electrical plug connection to the base of the motor housing), since it comes ungrounded from the factory.
I disassembled the outlet valve housing, and found wet silica gel beads inside, and the cylindrical basket that holds the silica was already starting to rust. I removed all the silica, cleaned out the housing, and replaced the silica with one of the cotton tampon type filters that come with the unit for the small external filter. It fit fine inside once I trimmed about 1/4" from the overall length of the tampon.
See all those fittings for the 3/8" hoses on the photos above? Yeah, well it turns out I needed small hose clamps on all of them even though they are barbed.
When I hooked up a water supply and pressure tested the system I had leaks blowing water all over the place... Also, that pump puts out 35 psi pressure, and the major flow restriction is the radiator. So that being last in the flow path caused the entire system to operate at a higher pressure than I wanted. So I decided, since the delta T on the cylinder heads really isn't significant, to use my original flow path of tank, pump, radiator, cylinders, tank. This way the higher pressure part of the system is only from the pump to the radiator.
More to follow once I receive the fittings from eBay. Its looking good so far, but you never know until its operationally tested...
