Material & Construction

This piece is machined from solid 6061-T6 billet aluminum stock rather than cast or stamped, which is why dual-carb and single-carb builders alike specify JayCee parts by name for Weber- and EMPI-based induction systems. The result is tighter tolerances at the carburetor interface and a part that seals and seats consistently, build after build.

Installation Notes

Dry-fit against your specific carburetor body before final assembly, and torque fasteners evenly in a criss-cross pattern to avoid warping the sealing surface. Because this is a fuel-system component, use a fuel-safe thread sealant or o-ring where called for, and re-check for leaks after the first heat cycle.
