Installation instructions for Tank connection 30018
• You will need to make a Ø 25 mm (1”) hole in the upper surface of the fuel
tank. Choose the location of the hole so that when the fuel tank tilts the end of
the intake pipe will stay in the fuel even if the tank is not full. If the end of the
intake pipe does not reach the fuel, the device will quickly choke on the air in
the fuel system.
• Cut the fuel intake pipe (Ø 3.17/0.8 mm) to the appropriate length. The end of
the pipe must not touch the bottom of the tank in order to keep water and sedi-
ment from the system. It is recommended to cut the pipe short enough to leave
the engine intake pipe at a lower level. This way the device cannot empty the
tank.
• Install the pipe straight end first and angle the two “ears” below the threaded
barrel inside the hole and then align the threaded barrel vertically so the ears
are hooked on the underside of the tank top. Carefully slip the rubber washer
over the bent pipe end and over the threaded barrel, followed by the metal
washer and the nut. Thread the nut to the threaded barrel and tighten, sealing
the fitting to the top surface of the tank.

fuel from the same fuel output line as the engine.
