Bill,
Eliminating flooding from leaky injectors was one reason for the bypass and turning
your pumps off to kill the engine does take care of this problem.......The other reason
was to provide a path to clear air from the fuel lines that can keep a fuel pump from
repriming if running a tank dry or to clear vapor pressure from hot fuel (hot start) on
our hot Okla./Texas summer days........

Call me crazy, but I have had no trouble with flooding since day one. That is probably because I always shut the engine down by turning off the fuel pump.
The original engine I bought for education was declared inop by its previous owner. Turns out it was only flooded (due to leaky injectors). I read about the problem and the fix like y'all are doing, but killing the pressure at shutdown seemed simpler to me.

Ben,
I tapped the ID of a Tee fitting to accept the motorcycle carb jet. Then I screwed the jet into the threaded hole with some Lock-tite to keep it in place.

Subject: [FlyRotary] Fuel system pressure bleed off
Group...
I am installing my fuel system on my Renesis right now. I seem to remember (correct me if I am wrong) that the consensus was to use a .020 orfice bypass of the regulator to bleed off the pressure in the event of pump prime loss.
My question is, how exactly are some of you going about this? Are you welding an AN fitting shut, then drilling it out to .020? Is there something of this nature commercially available? Suggestions? I have only to run the fuel lines, then wire the engine, a few other little misc. items, and I should be ready for first engine start.
