Our Part # 3415

Very limited quantities.
Use this needle and seat to repair stripped threads. 

Fits: Quadrajet and Dualjet carburetors

Installation Instructions:
Drill needle & Seat bore to .4375" using a sharp 7/16" drill.
Slightly chamfer leading edge of bore with .500" drill to ease installation.
Thoroughly clean casting and all passages.
Lightly lubricate o-rings with wd-40.
The lower section of the repair fitting is threaded.  This allows the O-rings to be expanded for a great seal. Slightly loosen the lower portion of the fitting.
By hand, press assembly in the newly drilled bore. You may need to gently tap it with a 3/8" deep socket to fully seat assembly.
Gently turn by hand the hex portion of fitting clockwise to tighten (snug) assembly, locking it into place.  Just use a deep 3/8" socket and turn with your fingers, do NOT use rachet to tighten!
