In doing some research, I discovered that there was apparently a magazine article published in the early 2000s that described this "low cost" alternative and several were built and flown this way. Once we got ours home, it all came out and the airplane is now plumbed and pumped according to plans. All is good. I know it's a long shot but thought I'd mention it.
Were your pressure readings weird all the time, or like my case, only when BOTH pumps were running?
