HOW-TO

How to Form and Flare Tubing Ends - Page 6

Photo 28 — The second tubing project is a fuel line between the firewall and the carburetor. The area where the fuel line will be located is the between firewall flare fitting on the left and the carburetor (below the blue tape). The blue tape was put in place to make a temporary sling to rest the level. The measuring tape shows a rise of 8 inches (to center of fitting). While the first tape acts as a vertical guide, a second tape (not photographed) is used to measure the reach (from the firewall).

Photo 29 — The original fuel line shows the bad bend at the red arrow. It's used as a pattern for the dimensions from the firewall, the hairpin curve around the exhaust manifold and back/down to the carburetor. The tubing was laid out on foam core as a square guide. The 8 inch rise dimension was already measured on the foam core. The 7 inches shown on the measuring tape is the reach from the firewall.

The third and final tubing project is a water line from the upper radiator hose to the heater with mounting to the firewall. This is a custom new installation where several routes could have been followed i.e. either over or under the intake manifold. The design planned to include a flat plate soldered on the line to utilize an existing firewall screw as a hard mounting point. Contrary to the advice given earlier, this tubing line started with the segment that will be hard mounted to the firewall and worked up to the radiator hose. Photo 32 shows comparisons of the pattern, the first attempt and the final version. Photos 33-35 provide details about this water line.

Photo 31 — The Gear Tie is again used to make a pattern for a water tubing line.  Since this is a new custom fabrication, several routes were considered when designing this water line. It was planned to include a thin plate to mount this tubing onto the firewall which dictated the high point and thus the overall route for this water line.

Photo 32 — Side by side comparison of the orange water line pattern, the first attempt and the final version (shown with the flare nut). This tubing was made using steel tubing with that was purchased with a protective coating. The coating was removed before sending it to the plater. Since the vertical segment is hard mounted to the firewall, it is the starting point for all dimensions and angles. Can you spot the problem with the middle line? It's the kink on the left side, below the vertical segment.
