Service Kits
An SU carburettor service kit contains all the gaskets, O-rings and seals that should be renewed as a matter of course whenever the carburettor is disturbed. Using a kit ensures no seal is reused that could fail shortly after reassembly.
SU Specialists service kits are specified by carburettor model — HS2, HS4, HS6, HIF38, HIF44 — and include every external and internal seal. For a more comprehensive rebuild including float needle valve and jet, see our Major Repair Kits.
