Mark, this pump uses an o-ring. It is the same o-ring on the pump and the
adapter. I have some laying around. Let me know if you need them, and I will put
two in an envelope.
Need a mailing address on my private email.

Kelly,
Wouldn't you know, I found my 13b front cover. As they say, "If it
had been a snake, it would have bit me." So, you can keep the one you have
(maybe make a clock out of it). It is off an '89 6-port engine. The
pump I have is off the same engine, so everything fits. Anybody know where
I can get a gasket to fit this pump?

Mark,
Do you have a 86-88 or 89-91 metering pump
?.............I have both covers but Richard's adapters are different
for these model years.............

Richard,
Thanks for the great information. That supports what instinct was
telling me. So, anywhere upstream of the butterfly should work?
I'm running three 1-barrel throttle-bodies on my p-port 3-rotor. If I
understand you, I should hook the check valve for each rotor upstream of the
respective TB butterfly, correct?
Mark
Mark,
you need the injection check valves hooked up to your intake plenum.
The oil intake only works with the pressure difference between the
combustion chamber and the plenum during the intake cycle. The check valve
prevents oil from being pushed into the vacuum lines by reverse pressure
fluctuations.
As far as the control lever is concerned, you have a good plan. You
may want to make the lever position adjustable so you can set the oil
consumption to a level that makes you and the engine feel good.
FWIW

Is
anyone running an oil metering pump (OMP) that can help me figure out how
the lines should be connected. I'm planning on using the Mazda banjo
fittings to hook up to the OMP, but what do I do with the check
valves. Do you connect the check valves to a vacuum source or just
block them off? Will the system work properly if I plug the check
valves? I plan on locking the lever in the full open position.
Will this work for a/c use? I'll be using Richard Sohn's adapter
with a 1 gallon reservoir filled with 2-stroke oil.
