Float Height
« on: February 06, 2026, 07:51:11 PM »
What is the correct float height for carb 17080212 with 0.135" seat and brass float? Using with a mechanical fuel pump, a pressure regulator set to 5-5.5 PSI, mounted on a 454 street/stock setup.

Rochester never used brass floats for any Quadrajet, with the original type nitrophyl float the setting is 3/8".

Thank you. The float has a brassy color, so I assumed it was brass; I have no idea! 😁
