OMP adjustment?

Hey, is it possible to adjust my OMP to put out MORE oil?

Hmmm, since the pump rate is controlled by a linkage to the throttle I would guess (and I do mean guess) that you could either adjust it or modify the rod that links it. Just convince the pump that your throttle is open more than it really is.

Someone else can probably give you a better answer than this....so here's a free bump.

I'd think you'd just add shims to the omp linkage. that way, it'd be responding to a higher rpm range. however, make sure it won't interfere with wot operations.

Haynes manual details how to test, and adjust, the OMP. I am assuming that you could use the method outlined there, and adjust it for a higher flow.

Yes, i tells how in the haynes manual. basically you loosen the lock nut at the pump, and turn the adjustment screw. turning it in increases the discharge.

I used a S4 omp which has four line vs. a GSL-SE omp which has two on my 13B.
