This is one of those times when a picture tells most of the story. This shows proper under chassis routing and mounting for fuel pipe, brake hydraulic pipe, wiring harness, and main battery cable. Thanks to Jim Ferguson in North Carolina for the picture.

Fuel and brake pipes run underneath the floor board mounting rail straddling the weld nuts. The larger fuel pipe is best protected in the corner next to the wide frame tube. These pipes are held in place by steel tabs that are welded to the frame and bent inward and upward around the pipes. The wiring harness and main battery cable are mounted just inboard of the floorboard mounting rails. These cables are held in place with large "P" clips turned in the upward direction to put the cables as high in the chassis as possible for best protection. The clips are screwed to vertical tabs that are welded to the frame at the inboard edge of the floor mount rail.

Where the fuel pipe and brake pipe come to the leaf spring, be sure the pipes are routed inboard in front of the spring bracket on the frame so the pipes do not go under the spring bracket at a point commonly used for jacking. The battery cable will be routed inboard and upward at the same location. The wiring harness will continue rearward along the outer frame tube following the upward arch over the rear axle. At the highest point of the arch the harness is secured to the under side of the frame with a "P" clip screwed to the same weld tab used for attaching the cable grounding wire ring lug.
