FUEL LINES
P/N 140057
WARNING! To preserve the warranty, the instructions must be read and followed
thoroughly and completely before and during installation.
This Demon™ fuel line is designed for use on Demon™ dual feed carburetors.
IMPORTANT! To prevent damage to the finish of the fuel line, always tighten the fittings
using a 5/8” flared nut wrench. This will also prevent “rounding” of the
hex heads.
1. Before installing the fuel line, inspect the fittings to ensure that they are free of any metal chips or burrs left over from the machining process.
Clean, if necessary. Otherwise, cross-threading and fuel leaks will result.
2. When all fuel inlet fitting threads are free of any contaminants, you may now install the fuel line to the carburetor. It is highly recommended to
initially start the threads by hand, at least 2-3 complete turns. Finish tightening with a 5/8” flared nut wrench.
3. Tighten the fuel line sufficiently to prevent fuel leakage, but not so tight that distortion or stripping will result.
NOTE: Your new fuel line is equipped with a 1/8” NPT pressure tap. The plug is lightly screwed in for shipping purposes. During
installation, the plug must be removed, coated with Teflon sealant, and reinstalled if the port will not be used for a pressure gauge.
If you wish to add a fuel pressure gauge, remove the plug and install a gauge with a 1/8” NPT stem. ONLY USE TEFLON SEALANT
ON NPT FITTINGS.
IMPORTANT! Demon™ does not recommend the use of Teflon tape on the carburetor inlet fittings. The tape could separate in the inlet
fitting and clog the inlet fuel filters, resulting in fuel starvation. If the fuel inlet filters were removed, or never installed,
Teflon tape particles could become lodged in the inlet needle and seat assembly and cause flooding and the possibility of a
fire.
4. Start the engine and check to ensure against fuel leakage. Correct, as necessary.
