While Filling Up

Thank You.
The last two times at the pump, there was no indication that I need to release the nozzle lever. The fuel reaches the very top of the filler neck, then spills onto the floor. I am wasting good money [89 octane is 2.75/gallon], and would appreciate opinions on what to look for to facilitate a repair.

Repair? Find a different fuel source. The filler nozzle is equipped with a pilot diaphragm, venturi/siphon tube through the product discharge tube nozzle, and a pawl that will disengage the main fuel valve when the vacuum/siphon air source is obstructed.

There is nothing wrong with your vehicle, only the pump/nozzle that you are using (or your methods).

I would have thought that the problem is with the gas station, but the spill occured at two different places. I use one tankful of gas every two weeks.
Your explanation of the mechanics behind the self-release nozzle is fascinating.

(or your methods)
You'll notice that I also mentioned the methods. If you are filling very slowly, there may not be enough liquid moving to create a pressure differential, and the obstruction of the vent siphon will not release the handle from the valve. It can be overflowed all day long with that method.

California and Massachusetts refuelling are even more of a problem, since the vapor recovery bellows also has to be compressed against the tank filler neck to activate the handle latch.

I had a 5,500 pound Chrysler with a Mopar 440 and Holley 750 c.f.m./ vacuum secondary, that seemed to get better mileage. Fuel is so f**king expensive, perhaps I should turn the old 'Bird into a turbo-diesel.
Twin-turbo.
I remember when regular gas was 98 octane, and less than $.25/gallon. Premium Getty was well over 100 octane, and my parent's '68 'Caddy loved it. That was a 472 engine (printed right on the air-cleaner. The Eldorado for 1968, was a 500 (and front-drive). Amazing stuff.

This doesn't have any relation to carbs, specifically. Let's move elsewhere.

Was there any reason for you to even bother to post such a comment? This website partially owes it's success to friendly banter. It is much more than just strictly-topic.

^^^^ haha diesel is just as if not more expensive then high-test gasoline. it cost almost 115 bucks to fill my chevy 3500 twice a week that gets 12 mpg. Now you need to get make it an alcohol car because the methanol for our sprint car is only 2.13 a gallon

I live in Brooklyn, with all the transplanted Russians. Vodka fits better, as it can be ingested too.
This is what I mean about friendly banter. Wonderful website, wonderful members.

Mr. Diesel [he was a real person] did not design a fast engine, simply an efficient one.
I saw a similar piece on T.V., about a woman who collects all the used frying oil from the resturants, to run her car.
My uncle had a Mercedes-Benz turbo-diesel with a straight-six.
Was kind of slow, even slower than slow, until the turbo kicked in; but the fuel mileage was outstanding. Smelled and rode like a truck.
