The nozzle is mounted using its external 1/8 NPT threads. Tighten the nozzle and nozzle holder assembly one
half turn past fi nger tight using GOOP to seal the threads.
Carb Plates are available for 4150 and 4500 style carburetors.
You can mount the nozzle in a plastic or rubber air inlet tube using a Nozzle Mounting Adapter (#15056). Weld-in
aluminum (#15057) and steel (#15058) bungs are also available.
TECH TIP: The recommended nozzle mounting point is before the throttle body/ throttle plate. If you mount the
nozzle after the throttle body/throttle plate (including use of a carb spacer plate) or below the reservoir, a Solenoid
Upgrade (#15055) must be used to prevent siphoning at idle or gravity feed.
Step 5 Nozzle Connection
Measure the distance from the pump outlet to the nozzle holder. Cut the ¼” tubing using utility knife. Make cuts
are as square as possible.
Ensure there are no kinks in the tubing and insert tubing into quick disconnects until fully seated. Gently pull on
tubing to ensure a good connection.
Use tie wraps to help route tubing and to ensure it doesn’t contact moving or hot parts in the engine compartment.
Have tubing connect to quick connect fi ttings at shallow angles. Having an immediate sharp bend may unseat the
tubing from the internal o-ring and create a leak.
Continual insertion and removal from quick connect fi ttings will mar the end of the tubing. Over time the internal
gripping teeth may lose their hold of the tubing which may create a leak. If this occurs simply remove the tubing
and make a fresh cut using a razor blade.
