You wont get far with your classic car without proper fuel transmission. So this unit should always work perfectly. A very important item for correct functioning is the carburation. Gas consumption will increase due to heavy use and leakage and what it even worse, a fire can arise in the engine compartment. We can deliver a suitable rebuild kit under # 2181-0 for revision of the 34 ICT Weber carburettors. This rebuild kit is delivered as a set for 1 carburettor.
