But - you knew that was coming - my personal opinion is that there are some auto parts that are battle tested, so to speak, with millions, maybe tens of millions of miles on them collectively. The performance parts are probably well engineered (and look very nice!) but don't have the long term experience and usage of the major mfgrs systems. Personally, and I will preface this with the fact that I do not fly a rotary (or any other aircraft at this point, though I've been through ground school in the mid 90s. Kids' needs intervened, now enrolling them into college, etc., hope springs eternal!), I have three custom Mazda rotary EFI auto installs and have settled on the late 80s-early 90s Toyota Supra mani referenced FPR for several reasons. No TSBs from the factory ever, able to shunt a lot of fuel and maintain 3 bar even if you have big or multiple pumps, cheap and easy to obtain. I have several thousands of miles of use on these (15000 on mine, all pretty hard use) using premix, no problems yet. I was concerned about the effect of premix on the diaphragms, don't know why, just a little concerned about putting non-spec fluids into critical devices. They're made of steel so you're free to easily weld/braze whatever you want onto it for connections. Just a thought. PS : Ed Anderson, hopefully I'm heading into the attic early tomorrow to retrieve that SAE paper I referred to earlier. -Mike
