Bernie,
   Good to hear you are running again........If the apparent flooding problem pops
up again and the fuel pressure continues to bleed off fairly rapidly you may still
have leaky injectors or as some have stated could be the fuel regulator is not
holding pressure.........The leaky injectors is a classic hi-mileage RX7 problem......
..If I recall correctly you have replaced some or all of your injectors........Were
the replaced injectors new or "rebuilt" (I do not know how you do more than
clean,flow test and check leakdown )?........Leakdown is only a problem if it is
the injectors and causes flooding which it does easily it seems for the 13B........
The easy fix for the RX7 has been the +/- .020 bypass oriface to bleed residual
fuel pressure to the return to the tank with the secondary benefit of providing
a way to clear an air lock in case of running a tank dry which some of our A/C
fuel systems (Not all) seem to be prone to........The bypass worked like a charm
for my old 88 RX7........I know I am restating old info but it worked for me in the
case of auto use and I plan on a bypass for my Delta fuel system........ The 13B
floods very easily and I recall the frustration of clearing it too well !! FWIW
