Most of us have known a few of these, where you pay for say 12 gallons and your tank only holds 10. AND your guage is at 1/4 when you begin pumping!

Most of these adjustable scam pumps have been removed. Anyone know if the new pumps can be rigged or other methods to cheat you?

I have a few stories on this subject as maybe you do too!

bigger problem is crooks putting devices to read your card and pin number, some are so slick nowadays that no one can tell unless you take the front cover off the pump

In this state, the Department of Weights and Measures regularly and randomly tests and seals all gas pumps.

Jeeez people....sorry but you have NO idea what you are talking about. If you pump 10 gallons at $3.00/gal OF COURSE it is going to read out $30.00.
What you fail to understand is that the flow its regulated by an adjustable valve. It is NOT tied in any way to the display screen.
Thus the valve can be adjusted to dispense 0.5 gallons instead of 1.0 gallon and your display will show you getting 1.0 gallon and the dollar amount being $3.00 although in reality you only got half of that.
However, after 30 years, I have NEVER known anyone stupid enough to do such a thing.

I don't know of any, but a good way to tell is here in Canada if it is ..1.25/ liter you pump in 10 liters and stop and look at the amount on the pump it should say $12.50 if it is higher than report that station right away there is a number on all gas pumps to call is you believe you are being scammed.

The question is, "Can the modern day pumps be rigged"? Obviously, the answer is "Yes", but being vigilant with respect to the certification stickers on the pumps can go a long way to protecting you from those who would steal your money

look for a current state sticker to be sure the meter is correct. since I use diesel I get fuel at a major truck stop that pumps lots of fuel and seems to always be consistent with my gauge

I noticed at No frills. I see the counter start but no fuel coming out. I seen it like .40 cents before it flows...
It still cheaper. I figure its from not having a check valve to prevent drainback...

I doubt that this is true, but notify your state division of weights and measures. Take a gallon can and fill it up to see if it is correct.

In Maine all stations are pump tested by the state for every grade of fuel at least once per year. There is no notice of when the inspections take place, so any scammers would get caught.
However I get more than my tank because I run down to fumes and tippy top it off each time.

streetirsx --

You need to do a little checking of your own. Tanks are buried in the ground, and the temperature down there doesn't vary but maybe a degree or so ALL YEAR. In short, there is no temperature fluctuation to worry about

Jef4ers. All dispensers, not pumps, are adjustable to regulate flow. Anytime a dispenser is installed it is calibrated using a certified test can several times. I can't speak for all in the business but we test all dispensers at least twice a year and more if we suspect a problem, as in gaining or losing inventory (yes it happens both ways). It is a simple thing to do, all you have to do is turn a knob one way or another.
However, as gasbuddy pointed out, we are in a customer service industry and the LAST thing you want to be known for is cheating the customer.
Has it, or can it be done? Of course it can. Just as one can buy off road diesel fuel, which is road tax exempt, and run it in their every day car or truck. Or move fuel from a low tax state to a high tax state and pocket the difference.
Guess it just depends on what problem(s) you wish to stress over.
How about doing business with someone you know to be a reputable person instead of chasing prices all over town. How about a locally owned and operated business man who lives in the city, pays taxes and supports their community instead of sending your money out of town, state or God forbid the country. Just saying......

What about when you are paying for nothing, when you put your credit card into the gas pump so it gets the details then you start pumping and about $10 later you realise nothing but air is coming out of the pump. (This happened to me across the border). When I went inside and told the woman at the counter she got angry like I was lying, I left, no gas and no refund, was angry and won't go back there again.

I've never checked. I've always assumed the gas station owner was honest and would not manipulate his pumps to cheat me. I pump til the pump stops. So, I am assuming the tank is full.

I wrote initially: "Most of these adjustable scam pumps have been removed. Anyone know if the new pumps can be rigged or other methods to cheat you?"

Yes most of those pumps have been removed and some of the stations have been shut down.

There are alot of subjects that some folks don't want us to think about and this is one of them.

Some have pointed out that dash guages are not accurate and that fuel tanks are only an approximation. Well, the dash guages are an approximation. The fuel tanks are actually pretty accurate. The manufacturers keep the volumes within 1% of the stated capacity. Overfilling can get another .2-.5 gallon extra.

The situation of being overcharged by unscrupulous station owners need to be discussed.

It is not possible to dispense an extra two gallons of gasoline (14 gallons) into a tank designed to hold 12 gallons. Fuel guages are an approximation as we stated but if the guage indicates 1/4 full then there usually is at least 1 gallon (probably alot more) remaining.
It is impossible to pump 15 gallons into a 12 gallon tank irregardless of the temperature or expansion.
If I have a problem, we return to the station with the certified test canister and measure it. Most problems occur along hiways traveled by outoftowners. The locals avoid those places.

<<<<<
I read alot of stories and opinions on here, gasbuddy. Why don't you want folks to make an informed decision as to being cautious about their service stations honesty?
Why don't you answer this question: Have you ever operated a gas station? Have you ever tampered with a dispensing counter or pump?
Let me be clear. Folks are paying too much for an honest gallon and we want to know if we are being cheated more than ONE way at the pump.
That discussion is just as important as posted pump prices.
Most of us know that the station owner is being squeezed by margins and the situation is ripe for shenanigans to start taking place at the retail level. Instead of trying to cover this up.....you should be aiding the discussion.

The State's weights and measures regulate pumps. You can lose your license if you are caught breaking the seal.

Here is a thing that no one gets, when a gas can says "one gallon" it means one gallon to the line that is drawn on the can. ALL gas cans have a bit of room at the top to allow for expansion for the gasoline, I have seen people fill up the gas to the very top and "fit" 1.20 gallons in a 1 gallon can.

Then people complain that the pump is not working right.

I suspect deliberate fraud is more difficult with the newer pumps and I haven't seen much of that here. Price fixing is another matter though.

If you have a doubt about a pump, then report it to your state division of weights and measures, plus take a gallon container and fill it up to see if you are getting exactly one gallon. I am betting that you will.

Not with todays technology, BUT all fuel pumps have one MAJOR FLAW they do NOT compensate for temperature changes. So for example, during the summer you might pump 1.5 gallons but because the fuel has expanded it might only be 1.35-1.4 gallons in reality..

Almost all fuel tank ratings are an estimate, a figure to give you a minimum of how much fuel a tank will have (under normal conditions); it's not uncommon for a fuel tank to hold more than the announced figure, not is it uncommon for drivers to "fill up to the top", a fill-up beyond the recommended level.
Second, The fuel gauge in a car is just that, a'gauge'. It's neither uncommon for the gauge to remain at the "full" level until after a significant amount of driving has been done, nor is it uncommon for a gauge to show "empty" when there's still a significant reserve in the fuel tank. The accuracy of automotive fuel gauges shouldn't be confused with the accuracy of fuel gauges in, say, aircraft, which is much more precise, much more expensive, and for which there is much greater accuracy needed.

But your asking "Anyone know if the new pumps can be rigged or other methods to cheat you?" sounds as if you believe that all gas stations are out to cheat customers, and that regular testing (and, in almost all cases, near immediate checking/testing following complaints) are neither accurate nor useful, because "they can be rigged" afterwards.

Of course new pumps can be "rigged", just as your computer can be hacked or attacked by a virus even though you've installed anti-virus and/or other protection, or your car stolen despite anti-theft devices, or your bank account hacked (or identity stolen) even though you don't give out your password or ATM account numbers. But just because it can be done, doesn't mean it is done. At least not frequently.

Sorry, but most gas stations are in the customer service business; that is, they're in business to make money, and to make money they need to provide a service that isn't questionable, and won't get them to lose their franchise, or fined, or closed either the franchisers or local government.

Rather than hearing your "stories", it would be better to hear about gas price posting. After all, that's what helps most other Gas Buddy members, our posting of gas prices so they can be informed shoppers. In my opinion.

They can all be adjusted....otherwise it is like putting in light fixtures where the bulbs can not be replaced. Any electromechanical device can malfunction and thus needs adjustment, not replacing.
In addition, just because your manual says you have a 12 gallon fuel tank, how accurate is that.
Your fuel gauge shows 1/4 tank, how accurate is that?
I can assure you neither is in the ball park accuracy of the pumps you are so concerned about.
