Installation Instructions for 15080 Stainless Steel Hard Line Kit

For 4150 style carburetors.

BE CAREFUL – DO NOT OVERTIGHTEN THE THREADED FITTINGS! Use a Teflon thread sealing compound to avoid leaks and to guard against galling of threads.


Check for leaks before starting your vehicle. Take precautions when working with gasoline – It is a fire hazard and is potentially explosive.

Regulator will mount below the bracket. The carburetor studs on the regulator side will need to be replaced with a minimum of 1/4” longer studs depending on the use of spacers.

  1. Read all of the Instructions before beginning the installation.
  2. Determine correct direction of bracket, it will only fit one way correctly. This can be determined by simply slipping bracket over the carburetor studs and checking for throttle linkage interference. Make sure that the throttle will open and close without interference. Bracket is designed to work on right side of carburetor – passenger side.
  3. Mount the regulator to the bracket using the supplied hardware.

Note: Care must be taken when removing the fasteners securing the upper and lower sections. There may be spring tension and/or a diaphragm that will need to be reassembled with care.

Note: Regulator will require that the four tubular spacers be placed between the top surface of the regulator and the mounting bracket.
