Gas overflows when filling up at gas station

Just picked one up today at West Marine. Will post how it works on Saturday. ]

I finally got around to installing this thing. It works great. When the whistle changes pitch, you stop filling. No spilling. It's a little obnoxious, but well worth it. Relatively easy to install.

If you fill up in the morning and the boat sits in the hot sun for a couple hours unused it can spit out the vent as well.

My understanding is that a car vents through the gas cap, so if you were to block the vent to keep your tank from venting the hose will click off. My 87 2001 vent is next to the fill so this makes it easy. Works every time for me

Modern cars do not vent gas through the gas cap. There is a vapor recovery system that traps gas vapors, and stores then in a charcoal cannister. When the engine is running again, fresh air is drawn back through the cannister, and the vapors are burned in the engine, and if your O2 sensor is working correctly, the fuel injector timing on the engine is adjusted to compensate.

Our centurion would not overspill but i hat to rotate the handle around so the trigger pulled up so the sensor was resting on the bottom part of the filler kneck.

The crappy thing about that boat was that as soon as you drove down the road like .5 of a gallon of fuel would slosh out the vend and piss down the side of the boat trailer and tended to splash all down the side of the boat. What was even nicer was that the station closest to the lake had like 10 speed mountains you had to drive over just in case you didn't overfill you fuel would slosh and spill out.

Just another reason I am looking to buy a CC
