Hmmm. Never heard of that, but mine does whistle while filling and I wondered why.

Sorta off topic, but is it better to store the car with a full or half tank? I'll probably start it every few weeks.

My filler neck whistles too when the tank is nearing the full mark, (1/2 to 3/4 full). Figured out is air from the tank escaping through the breather tube. I thought it was because of modifications done to my tank and filler neck because of the fuel injection, electric fuel pump, and matching plastic, clicker style gas cap. Newer cars do not have this tube. I don't see why it couldn't be eliminated, but I haven't tried it yet.
Rumor is that full tank is better. As for short term storage, as in over the Winter, I believe you do your car no favors by starting it every few weeks. The engine and exhaust system don't get hot enough to burn off the condensation formed by cold starts, and remain in the crank case and exhaust system until it is driven for longer periods of time.

Hum...not sure if it can be fixed if it is not operating...or what exactly would cause it to not operate properly or at all. It was called Whistle Guard and either started or stopped whistling when you were getting close to filling the tank. I believe the filler area had changed to a more boxed in area and if the tank was over-filled led to the possibility of fuel spilling onto the lacquer finish and causing that streak you see many times from the filler flap. You might removed the filler and inspect it to see if you can see anything obviously amiss. I suppose someone also could have switched out tanks at some point and did not put a 1951-52 tank back in. I don't know if it this feature returned in '53 or '54.

Back before auto shutoff nozzels at the gas pumps
it was to let them know when the tank was almost
full ( the whistle would stop ).

Exactly!
I bought my 51 from Granddad in 62, just before going to Nam. Back then it whistled------------and it still does. It has the original tank, filler tube, and vent tube with a genuine 51 cap.

The newer fuels with ethanol suck water from the air, so it's better to store with a full tank. It's also a good idea to add some Stabil when you fill up the tank.

Good luck with yours!

The whistle was an option or standard? mine has it, and it hasn't failed me yet. The pitch is high, then gets lower, and stops. I have never overfilled the tank if I stop right when the whistle stops. 10,000 miles. To answer the OPs question, if its there but doesn't sound, I'd say start with visual inspection for physical damage or obvious grime, and clean with carb cleaner if its the latter, trying to avoid it all going down into the tank.



Winter storage... Full tank is best, non ethanol. Do NOT start it at all unless you intened to let it warm up and run for a good long while when warm. When a car starts and runs cold, condensation is all in the exhaust (and in the motor) and its particularly acidic becuase of combustion byproduct. This will rot out your exhaust in short order.

We have a 6 month winter (our second 12" snowfall is occurring now - 11/28! and we get them into April) and over the years, I have stored my car full with non ethanol, and only started it when I needed to pull it out move it, but when doing so, gave it like 30 minutes plus to enjoy being alive

also, in years past I have used Satbil but haven't the last few, partially because of forgetfulness but then in faith that the non ethanol helps.

Also, as terrible as it probably is, when we get a nice sunny winter day with dry roads, I usually take a 20 or 30 mile cruise. The photo shows a puddle and wet car tracks... its the parking lot, not the road. I usually wait until I see the roads dry a whole day in my work car, and if there is no rain or snow before I can get to my 50, I drive it.

I personally think the whistle was a design flaw that GM made the best of. Up until now I had never heard of the whistle being a safety feature. In fact I find it kind of embarrassing at busy gas stations. I'm the only one whistling. I don't care for that crazy whistle to draw even more attention . Last Winter, I rolled up a piece of window screen to try and disrupt the air flow, and stuffed it into the smaller tube, didn't change much. I may just remove and plug the noisy thing.

Dave,

If you have a lake nearby, or can get to a marina that sells gas, some of them still have leaded gasoline. Expensive, yes. If I were going to store it for a winter, I'd run it dry. Then put 5-10 gallons of leaded in the tank. Start it up and you should be good to go.

The unleaded mix they have now is really hard on the fuel pump diaphragm, and the seals on the carburetor pump.

Don't plug the vent tube; unless you enjoy taking an hour to fill the tank; along with a number of blow backs of fuel.

I gassed up today. Mid-grade, no ethanol. It whistled while filling, changed tune and stopped, then the pump cut off. I couldn't squeeze much in after that.

The wording in the 1951 Australian GMH owners manual reads:
"On Sedans, a whistle system is installed in the vent pipe. This whistle is audible until the fuel level reaches a point one gallon short of full capacity"

I wouldn't want that, but the vent tube and the filler tube are at the same level on the tank so, I don't know why that would make any difference.

An after thought. When I was a kid, I had a 52 Bel Air, I don't remember that annoying whistle when filling the tank. It has been said in earlier posts that, that "safety" feature was only available on the sedans...I would think the more expensive Bel Air would have that "option" if were really an intentional safety feature.

Stop and think what the vent tube is doing while you are filling the fill tube with gasoline!

Off topic but related, would parking my '50 (no gas leaks, stock tank) in a basement of a house make the house smell like gas? i have to imagine it would as there is no means of capturing vapor...

I see 2blu's answer, but growing up in Pennsylvania and West Virginia our garages were under the house. It was separated from the rest of the basement, but there were rooms above the garage area. We did not notice any smell of gasoline, etc. but I tend to agree that some smells would be present.

Ya, ok, removing the vent tube is not a good idea. But, the whistle has got to go Haha! It's down a ways on the to do list, hopefully, with a little thought, it will be an easy "fix". I have major engine work that has priority for the time being.

I guess I missed the location of the garage but with my wife it would not make any difference at all. She can smell gas fumes from just about any where. Me, I burned my nose out years ago

I threw mine out accidentally when I installed a new tank. I wish I could somehow fabricate a new one to install in the rubber vent hose. this would be easy to do but I'm just not sure how big the small hole is in this whistle. so if anyone is doing away with theirs please get some dimensions and post what they find so I could get mine whistling again.
thanks in advance, bill

Yea not cool. I just wondered because my wife and I had chatted about a finshed basement (drywall, wood/carpet flooring, drop ceiling) with the chevy right in the middle becuase, why not? she was down with it... shame it wouldn't work out. There goes one of my better crazy ideas up in smoke.

The whistle... see about filling your tank 10-20 times before removing it. it is quite handy...

Bill, not sure what you mean, but here goes, I'm pretty sure that there is no whistle installed in the vent tube. Like I said before, just a design flaw in the way the tube curves, and attaches at the filler neck that makes it whistle.

When I had my old tank removed I seen a piece that looked to be pressed into the vent tube and if I were to guess, the hole was 1/8" diameter. I figure If I were to machine something to fit as close to the tank inside the rubber vent hose it might recreate the whistle sound. So if someone here were changing their tank and could verify this it would be very helpful.
later, bill

Where was the piece with the 1/8" hole pressed into? I've had my tank and filler neck out more than once and never noticed anything like that, but then I wasn't looking for something like that either.
