1. GENERAL INFORMATION
1.1 The autopilot/Verado hydraulic hose kit provides the necessary parts to install
Furuno/Accu-Steer reversing pump sets with Verado Hydraulic Steering
systems.
1.2 Standard installation practices should be exercised. Hoses should be installed
in such a manner to avoid sharp bends and chafing. All hoses should be tied
down using tie straps or similar devices.

3. SYSTEM DESCRIPTION AND CONNECTIONS
3.1 Oil from the Pump Unit flows to the helm through port <P> and returns to the
Pump Unit from port <R> (This is referred to as the primary circuit). The
pump unit has a pressure relief valve built in. The helm pump has a non
return check valve located internally, in the pressure port. As the steering
wheel on helm pump is rotated in the starboard direction for example,
internal valving inside the helm pump, directs the oil from the pressure port
into the starboard line and the oil from the port line i s directed to the return
port. The starboard and port lines are marked L (left) and R (right) on the
back of the helm pump.
3.2 When mult iple helm pump s are used the primary circui t lines (P and T) are
connected in series, as show n in Figures 2.3 and 2.4. The output ports of the
multiple helm pumps (L and R) are connected in parallel.
3.3 The autopilot reversing pumpset is connected in parallel with the helm pump
outlets, as shown in one line drawings
3.4 The Tee fitti ngs and adapters (SAE -06 to SAE -04) suppli ed connect directly
to the reversing pumpset using the SAE-06 ports in the pump block.
3.5 The hoses from the helm pump ( L and R) are relocated to the outlet fittings in
the reversing p umpset. The hosed suppli ed are connected between the hel m
pump (L and R) and the other side of the tees on the reversing pumpset.
3.6 The fill line between the lower helm and the Pump Unit is to be cut and a hose
barbed tee insert ed. Sma ll gear cl amps a re provi ded to ensu re the h ose barb
connections do n ot come apart. The third p ort from the Tee is connect ed to
the fill port on the reversing pumpset. This fill line should have a gradual
slope from the reversing pump to the Tee to allow air to escape from the
pumpset.
