NOT SURE?
Which one is the high pressure hose? The hose with heavy duty crimped on fittings. The low pressure return
lines from the steering box or hydroboost both end up at the pump reservoir will have hose clamps or some-
thing similar.
Does the factory hose have a sensor in it? What this does is increase the rpm of the engine slightly when there
is high power steering pump pressure during idle. We have found this is not needed. Remove it from the factory
hose and install it back into the wiring harness plug. Tape it securely in place. The vehicles computer will not be
affected.
INSTALL THE ADAPTERS
Take the MM adapter kit for the vehicle; match the fittings up to those on the factory hose you removed. Re-use
the factory “O” rings; install them on MM fittings if required. There may be more than two fittings in the kit
due to multiple applications. You will only need two of them. Install them and tighten to the factory specifica-
tions. Take the solenoid fittings (“M”/90-50067 and “O”/90-50091) place into the “P” and “T” ports of the black
solenoid valve block. You will have to look and see where they will best suit your application in mating up with
the hoses from the engine bay. Then add the 90 degree “N”/90-50060 fitting to the straight fitting “O”/90-50091
you just installed. Remember the hoses will come thru either the grill or under the truck in an open area. When
you are sure of where the fittings will face, tighten them in place making sure the “O” ring is compressed (tight)
or for the flare fitting, ¼ turn past finger tight.
