Hi Richard,
 
Do the injector valves vary the amount of oil injected = based on=20 load?  I
have dissassembled a pump from a 13BT and it looks to be a=20 positive
displacement type with no apparent pressure relief=20 function.  I do not
have any "injector valves", just plain old banjo bolts that = thread=20 into
the housings, a jet sits in the bottom of the hole below = the banjo=20 bolt.
What am I missing?
 
Thanks -- Ian

the 12A pump is way to small for the 13B. According to the = spec.=20 the 12A
pump is pumping 2.0 - 2.5 cc  in 6 minutes on its = two=20 lines with the
engine running at 2000RPM.
The 13B NT does 4.5-5.5 cc on two lines in 5 minutes engine = running=20 at
2000RPM. The Turbo setting does 5.2 - 6.6 under the same=20 condition.
One more thing, if you use the OMP. You must retain the = injector=20 valves
sitting on the rotor housing and the intake manifold. Their = vacuum=20 line is
hooked up to the intake plenum. These valves do the oil = injection,=20 the OMP
only supplies the oil!
I hope this answers the question.
