After seeing the awful fire story this week, I decided to upgrade the fuel lines in my 914 engine bay. So from where the Tangerine SS fuel line emerges from the tunnel into the engine bay, I removed my system of: generic rubber fuel lines with screw clamps, fuel regulator with fuel gauge, and intakes from the Weber carbs, from my 2.7 liter 911 engine. Took this assembly to Mesa Hose in Costa Mesa, CA, and had them replace the hoses and clamps and install threaded connections, and weld up threaded connections on the carb inlets. The pic shows the assembly before installing, with the left hand hose end to be connected to the tunnel fuel line, and the other two ends to be thread connected to the racing style welded Weber carb intakes shown in the pic. The fuel line has a teflon inner and outer shell with a SS braided tube sandwiched between the teflon inner and outer tubes. There is also a reusable inline filter that can be removed and flush/cleaned. These guys know what they are doing. So I feel the $295 spent was well worth it.

Make sure the pressure gauge is mounted on the chassis so it’s weight is not on the like (which vibrates as the motor rocks on its mounts)
I’ve seen metal fittings crack from vibrations I’ve seen a fuel gauge that wasn’t properly mounted and isolated start a motor fire. A crack in the fitting became a high pressure spray and took the motor with it |
