If you’ve spotted any small (or large) dirty/oily stains running down the side of your Weber DGV carb, it could be a sign that you need to replace the top cover gasket.
With minimal effort you can swap out your old gasket for a new item and keep the fuel where it should be.
This gasket can be damaged when regularly removing the top cover gasket during tuning, so be careful - or better yet keep a spare in your inventory.
This gasket fits the Weber 32/36 DGV, including 5A. It also fits Weber DGAV and DGEV carbs.
