Fuel Injection Air BleedsSet of 8 $150.00
These air bleeds are used for balancing the idle temperatures on an injected engine; mechanical or electronic. Simply drill and tap your manifold 1/4" NPT below the butterfly and screw these in. They will adjust anywhere from no hole to a 5/16" hole. Our experience is that all the commercial needle valves would not flow enough, so this was our solution.
