I need some ideas on how to get fluid to the rear hydraulic cylinder with running a hose from the front steer to the rear, and pictures are always nice to look at. :D

On my 4 wheel steer project I used normal hydralic lines all the way from the valve to the rear crossmember. From there I use hoses. That kept the cost down.

Most definately use hard lines as far as possible. The pressure inside of a rubber line will cause it to expand and contract and not give you complete and accurate control. The higher the pressure the more prevelant this is. Try to use the rubber lines just at the very ends and then make them just long enough to take up for the travel. It would also be a good idea to use some sort of hose guard on them. It will save them from getting carved up on the rocks!

Check out the Aeroquip Teflon lined racing hose. It is the coolest hose I have ever used. Lefthander Chassis has the cheapest prices on the fittings.

There's lots of good tech on hydraulic plumbing at these links, from the ads and disads ot tube and hose to catalogues, specs, etc.

5. Plumbing / Lines

5-1. Types of Circulatory Systems.

Pipes and fittings, with their necessary seals, make up a circulatory system of liquid-powered equipment. Properly selecting and installing these components are very important. If improperly selected or installed, the result would be serious power loss or harmful liquid contamination. The following is a list of some of the basic requirements of a circulatory system:

Lines must be strong enough to contain s liquid at s desired working pressure and the surges in pressure that may develop in s system.
Lines must be strong enough to support the components that are mounted on them.
Terminal fittings must be at all junctions where parts must be removed for repair or replacement.
Line supports must be capable of damping the shock caused by pressure surges.
Lines should have smooth interiors to reduce turbulent flow.
Lines must have the correct size for the required liquid flow.
Lines must be kept clean by regular flushing or purging.
Sources of contaminants must be eliminated.
The three common types of lines in liquid-powered systems are pipes, tubing, and flexible hose, which are also referred to as rigid, semi rigid, and flexible line.
