the 1951 Bug had no fuel gauge

[Brock]

When Consumer Reports tested the 1951 VW Beetle, its 'low fuel warning' was the engine sputtering out. To avoid getting stranded, drivers relied on two bizarre analog workarounds.

Before setting off, drivers checked their fuel level manually using a literal wooden stick. You had to open the front trunk, unscrew the gas cap on top of the tank, and dip the dowel inside. Gas stations frequently handed out these wooden dipsticks as promotional items, branded with their logos and etched with markings for liters or gallons.

The real ingenuity, however, happened on the road. The Beetle’s fuel tank featured a dual-pickup system controlled by a petcock valve—a small lever located near the driver’s right foot, just above the floorboards on the firewall. The normal setting, marked "Main," drew fuel from a pipe that sat about two inches above the bottom of the gas tank.

When the fuel level dropped below the top of that main pipe, the engine would suddenly starve for gas and begin to sputter. This was the driver’s cue. Without panicking, the driver had to quickly reach down—or deftly use the toe of their shoe—and flip the lever 180 degrees to the "Reserve" position. This switched the fuel intake to a secondary pipe at the very bottom of the tank, unlocking the remaining 1.3 gallons (about 5 liters) of fuel. The sputtering engine would catch and roar back to life, buying the driver roughly 30 to 40 miles to find the nearest gas station.

Volkswagen eventually added mechanical gas gauges to standard Beetles in 1962, phasing out the manual reserve system. Until then, the system functioned flawlessly, provided the driver remembered one crucial rule: resetting the lever after a fill-up. If you forgot and left the lever pointing to "Reserve," the car drew from the bottom of the tank the entire time. The next time the engine sputtered on the highway, reaching down to flip the lever wouldn't save you—it just meant the tank was completely, hopelessly empty.

Kind of like General Aviation aircraft.  I had a truck with dual tanks and a switch, tanks were large, but still found that feature handy.  Only bad part was the position of the valve switch.  I had to stop to reach it.

Motorcycles don't have a three position switch - off/main/reserve - anymore?

 

I was out with a friend one time. His bike quit. So he reaches down under the tank and he flips a switch, and then he fired his bike up. I asked what the deal was and he explained that the main tank had just run dry and he had put it on the reserve and we needed to go find a gas station.

 

Later that day he is letting me ride his bike. I have gotten about three blocks from the house when it stopped. Out of gas?? Dammit! And I reached down under the tank and turn it on reserve. And then I think - Wait a minute. He just filled it up. There ain't no way it's out of gas. And I flipped the switch back over to where it had been. And then, just for the hell of it, I tried to start it. Fired right up. And I go about two more blocks and it quits again. So I push it all the way back, cussing.

 

That's when I learned it is not a two position switch - main and reserve - but is a three position switch - main, reserve, and off. And when he had parked it at my house he put it off. And when I went out to ride it I didn't know any better, so I left it off.

 

On the gas in the line I got that three blocks or so. When I thought I was putting it on reserve, I was actually putting it back on main. And then I turned it off again thinking I was taking it off of reserve back to main, but in that short length of time that I had had it on main, the gas line had filled back up. And when I tried to start it it started. And I rode it another two blocks and the gas line was empty again.

My parents had a ‘66 Beetle with the recently introduced gas gauge. As the gas sloshed around while driving, so did the needle. It was in constant motion. 
 

The car also had windshield washers. There was no pump as it ran off the spare tire air pressure, from a hose connected to the tire valve. It was a great incentive to keep the spare filled with air.

I had a '61 Fiat 600 coupe with a tiny water cooled engine IN THE BACK and a fuel tank in the front.

 

It had a red light that came on when you had about a half gallon of gas left.  It also was so precision engineered that the engine would freeze up when the radiator leaked all two quarts of water out.  On a summer's day on Okinawa that was pretty often.  Not a problem because everyone that had one of those cars carried a couple of water bags.  The engine seized up, you punched the clutch, and coasted off the road, and shut it off.  Wait 15 minutes or so for it to cool down, and everything loosened back up, add some water and go on your way.

 

Side windows were pulled up and down with canvas straps and held up with a snap.  Windshield wiper (just one) was manual, driver's seat was adjustable by a pair of pillows.  No door locks. No glove box but a tiny shelf big enough for a deck of cards.  One tiny rear view mirror was out on the left fender.

 

No high beam headlights, one tail / brake light, no heater, no radio, no jack but a jack handle that doubled as an engine crank, a flat spare tire with a hand pump, and painted steel floors. I always carried two quart bottles of recycled motor oil, too.

 

It had a speedometer that top out a 45 mph, which was okay because the speed limit on all public roads on Okinawa was 30 mph.

 

I bought that little monster for $65.00 from an Army 1Lt who was shipping back stateside.  I sold it 11 months later for $65.00 and bought a better car.  Had to be better.  A worse one was impossible.

I had a 1966 Beetle with an auxiliary in car heater that could cook you out of the car. It was a necessity here in Canada.

We (Big Red and I) currently own a 1962 Beetle, we stripped down and took apart, sand blasted it and repainted it.

That's when we found out it was really HERBIE!

Retired from the Disney franchise, he's been running around Ottawa now for a few years, with Big Red.

Back in the 70's we had a John Deere 3020. As long as the fuel gage was wiggling the fuel level was fine.  When it stopped it was time to head to the house for fuel.  Went to work for a neighbor that had a John Deere 5020 and a 1466 International Harvester. The fuel gage in the 5020 behaved just like our 3020.

One day I was prepping a field for planting. Knew the fuel was low but I figured that as long as the fuel gage wiggled I was ok. Boy was I wrong.  Had to walk 3 miles back to the house. After filling the tank and replacing the collapsed fuel filters, it took almost two hours to hand prime the fuel system and then bleed all the air out of the injectors. From then on I NEVER let the fuel level get anywhere close to empty.

Almost all bikes made now have fuel injection instead of carburetor so no more petcock, just an idiot light. Also no more choke.

When I was growing up, we had a 65...that heater would flat cook ya outta there! It wasn't a necessity in Florida though.

When I was flying light aircraft, they all had fuel gages. And my instructors told us NEVER to trust them! Dip the stick, figure out how long you plan to fly plus a reserve, and land someplace to get more fuel.

My family had a ‘59 bug with no gas gauge and a gasoline heater.  My mother was afraid of the gas heater and wouldn’t use it. The reserve tank was not a separate tank, it was the lower portion of the gas tank.  There was a small lever on the fire wall that you really could only reach with your foot.  And if you used the reserve you had to remember to move it back to main or it would not fill the reserve section!  I never figured out how that aspect worked mechanically.  
Later we had a ‘63 that eventually became mine.  It had a gauge but no gas heater.  The so called “heater” from that air cooled engine was nearly worthless in a Vermont winter.  I kept a windshield scraper inside so I could scrape the inside of the windshield!

 

Now today, my 2009 Vulcan 500 still does not have a gas gauge.  The petcock is main and reserve, no “off” position.

That's such a clever piece of old-school engineering. No electronics, no warning lights-just a wooden stick and a reserve lever!

The reserve system was actually pretty smart, but I can imagine forgetting to switch it back after filling up was a painful lesson. Definitely a different era of driving!

[Alpo]

That's kind of funny. Didn't know that people were that stupid.

 

My first car was a 64 Ford Fairlane with 170 6-cylinder and a three on the tree.

 

The gas gauge would only go to 3/4. So when it read empty there was between a quarter and a half a tank left. You could not trust the gauge.

 

It had a 16-gallon tank and it got about 16 miles per gallon in town, so I just kept track of the mileage. And when I had over 200 miles on the tank I started looking for a gas station.

 

16 gallons X 16 miles is 256 mily, so that gave me 50 miles to get more gas.

 

My current truck also has an in-op gas gauge. And I also buy gas based on how far I've driven.

I used to have a red Firestone scraper on the visor of my Karmin Ghia 🤠. Never had to scrape the outside!

I did the same when I was riding Harleys. Never trusted the gauge.. Bike got between 35 and 45 MPG depending on how it was ridden.  I always started looking for fuel at the 150 mile mark.

Most trips we planned fuel stops every 120 miles.

I had a kind of inside frost shields that adhered to the windows, on the inside and kept that part of the window frost free.

Please expand.  Was this a film that was applied like window tint and it prevented frost from forming?

[Cold Lake Kid, SASS # 51474]

No, they were a plastic/vinyl clear sheet with a self-adhesive edge all way around,

You removed the protective cover on the self-adhesive edging, positioned the thing where you needed it to be and pressed the edges to seal it on the window.

You could still roll the side windows up and down, if you had to..

I used the larger versions on the front and rear windows and smaller ones on the side windows.

We used to buy them at Canadian Tire.

I'll have to look this fall to see if they still have them, but we don't use our Beetle in the winter. HERBIE vacations in the Inside,  heated Ottawa Auto Vault during the cold snowy weather, 'cause he's getting a little too old, at 64, to brave Canadian winters!
