One hose is air'd and the other three have oil? Swap the air hose with one that has oil. Then drive the car twenty miles and see if the problem has traveled from one place to the other.

Or just hold the omp rod full up while holding the throttle to over two grand for five minutes or so to see it the line fills up.

If the original air line still has nothing but air, the problem lies in the hose itself and not an obstrution in the OMP.

Or how 'bout this. Take the ai rline off the omp. Run the engine for five minutes at two grand plus with the omp rod full up. If oil comes out the pump steadily, then the omp is fine. Reconnect the air line and do the same. Two grand with the omp rod full up. WATCH the air line. You should see oil slllllloooooowlllly ooch up the line til full.
