What You'll Learn
The fuel line runs up the tunnel
The tunnel route for the fuel line was used on early 1967 models of the Ford Mustang. These early models had a 5/16" fuel line. Later in 1967, the fuel line was moved to the rocker route, and this change remained in place through to 1973. The rocker route is a more exposed location for the fuel line, and it is not covered in the same way as the tunnel route.
The tunnel route for the fuel line is a straightforward and effective way to route the fuel line on the 1967 Ford Mustang. It is a direct route from the fuel tank to the engine, and it keeps the fuel line protected and out of the way. This route was used on early 1967 models, and it is a reliable and efficient way to route the fuel line on this car.

The fuel line runs up the rocker panel
If you are converting an early 1967 convertible to EFI, you can use the existing 5/16's fuel line for the return line and add a 3/8's supply line. You can run a late 1967 line up the rocker panel, but you may need to secure it with Adel clamps. You can also use nuts and bolts, with the nut under the car, but this will take longer.

The fuel line is protected by a heavy steel cover
The heavy steel cover protects the fuel line at the transition to the rocker route. This is sometimes hard to come by, and some people choose to tie-wrap a new nickel-copper line to the old line with heavy-duty tie-wraps.

The fuel line can be replaced with a 3/8 nickel-copper line
The fuel line on a 1967 Ford LTD can be replaced with a 3/8 nickel-copper line. The original line runs up the tunnel, but later in 1967, Ford moved the fuel line out of the tunnel to the rocker route. This means that the 3/8 nickel-copper line can be used as a replacement for the original 5/16 fuel line.
The 3/8 nickel-copper line can be tied to the old 5/16 line with heavy-duty tie-wraps. The old line can be cut at the firewall, and high-pressure rubber lines can be run from there to the Sniper, through right-angle brass fittings on a bracket on the firewall behind the Sniper.
Alternatively, the 3/8 nickel-copper line can be run next to the old line and secured with Adel clamps. This method is suggested by a user on a vintage Mustang forum, who notes that it is a simpler method than using nuts and bolts.
It is important to note that the late 1967 Ford LTDs had a heavy steel protective fuel line cover at the transition to the rocker route. This bracket can be hard to come by, so it may be necessary to source this part separately if it is not already included with the 3/8 nickel-copper line.
