Edelbrock Carb dripping fuel in after shut down..

OM Mopar,
How do you explain the 'boiling' when the OP has the problem with a cold engine? Sorry, not buying that a return line is needed. Plenty of carbs out there not leaking & not using a return line.

Post #10 is also right on the money. Check the alum plugs in the carb base for leakage.

Believe what you want. They didn't apply the return filter on all unleaded fuel cars for no reason. And not all carbs have hollow brass floats. Also the OP never said the engine was cold. He said he ran it around the block. Unless he had Ice on the engine I would say it was warm.

Leaving fuel pressure dead ended at the needle and seat is never good for the engine when shutting it off.

And how do you know what pressure is against the needle with a manual pump without a gauge install between the pump and carb?

The return prevents the pressure from being trapped. Ethanol has a low boiling point and foams. You cannot stop fuel foam with a float that sinks in it. The fuel foams from heat after you shut the engine down more than when its running. When the engine is running it is always adding cool fuel. A return keeps the fuel cooler at the carb.

I really don't care if you believe me or not you arer not running the same crap fuel where your at. You always have your objective comments with me . And that my friend is a fact. If I would tell you the sky was blue your sky would be pink.
