8 Using provided fittings in the best orientation and optional
configuration, connect the long hoses from the manifold
block to the TFC valve. Loop the hoses to accommodate
movement during mast tilting. The lower manifold block
port connects to the CLAMP IN port on the TFC valve. The
upper manifold block port connects to the CLAMP OUT
port on the TFC valve as shown.

port on the TFC Valve to the DOWN STREAM side of the
return line filter (to eliminate the variable effects of filter
back pressure).
