Installation Instructions for 15125 & 15126 Fuel/Nitrous Solenoid Mounting Brackets

Important Note

It may be necessary to space the bracket upward, depending on manifold profile and carburetor type. 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. (Note: On late model Holley 4500 Series Carburetors it is necessary to shim bracket upward with spacers supplied.) All brackets are designed to work on right side of carburetor — passenger side.
3. Mount the solenoid to the bracket using the supplied hardware as indicated in the chart below.
4. Mount the solenoid and bracket assembly to carburetor studs.
