Wish I could give a firm date. Just about everything is ready, but the wiring harness I'm trying to have made is causing me problems. I want to supply a nice "drop in" harness that makes install easy, but getting one made seems to be a problem. I've contacted 2 reputable harness companies, the first one strung me along for a month before deciding my quantities were too small, the second only waited a few days. Trying to find someone that will build it how I want, the quality I want, etc...and do it in batch sizes appropriate to my company size. Got a few calls out now, waiting for replies.
It will be complete though, with filtration options, pump, vibration isolated mounting bracket, harness, etc. I just have to wrap up the details and get them assembled and ready to sell.
