PMO Float Level Gauge — Carburetor Fuel Level Setting Tool | PMO Carbs, Porsche 911 (PM-O405-0)

Float level is the setting everyone guesses at and nobody should. Get it wrong and you get a rich bog off idle, fuel slopping out under cornering, or a lean stumble you'll blame on jetting for a month. The PMO Float Level Gauge (PM-O405-0) lets you set the fuel height in the bowl to an actual measurement, on the bench or on the car.

Features

• Measures actual float level instead of relying on a bent-tab estimate.
• Makes the setting repeatable across all six bowls, so the carburetors match each other.
• Made in the USA by PMO.
• A buy-once shop tool — it will outlast several rebuilds.
