Venturi Gage 0-7448 350 cfm

This gauge will fit around the booster from the top and should not go into the Venturi. This would also be a good time to check the Venturi bore to see if it has elongated of “Egg-Shaped”. This condition will be easy to spot at this time, as
the gauge will not go in but you can see light around the front and backside of the gauge showing the Venturi has been altered. Do not question a slight imperfection, as a cheated up Venturi will be easy to spot.
