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.
