If you have warped Accelerator Pump Housing Covers, fixing the fuel leaks is next to impossible! These new covers are part number 30 on most Weber Parts diagrams. the image shows the complete Accelerator Pump, but only part 30 (the Pump Cover) is included as this part. You must also specify the carb you need the cover for. Looking at the cooling fan, the Left Bank (#1,2,3) is on the left with the Right Bank (#4,5,6) naturally on the right.
