QQQ about Auto"s Gas Gauge

Phillips · 10-21-2009, 04:34 PM

I was just wondering why....

Some Gas Station that I had filled the gas to my monster truck done. I turned on and see immediate response how much level gas on the gauge.

BUT....

Another Gas station and its slow response level on the gauge?

Bottesini · 10-21-2009, 07:39 PM

Colder weather and the thing inside the tank may rise more slowly?

Phillips · 10-21-2009, 07:41 PM

It's happening all year!

Bottesini · 10-21-2009, 07:44 PM

Don't know then!

Phillips · 10-21-2009, 07:48 PM

Yep

It is not only my monster truck it is happening to my other cars too!

Weather is the issue. Was your truck parked on level lot or sloped lot

I don't think to see gas station on a sloped lot? However

Two different way Gas stations that I am done with gas and turn on an engine. There quickly gas gauge with a level!...... Another way, I have to wait and drove about one or more miles Then Gas Gauge final complete with a level?

I think something with weak or stronger unleaded gasoline's Odor link to Gas gauge?

I would point at speed of pump, not all pump have same speed. Seriously, I once had diesel vehicle, and anytime I fill diesel at local gas station, it takes about same amount time to fill as regular gas (2-3 minutes), BUT when I stop at truck stop, and used 18 wheelers island, CHAMP, it filled my tank less than 10 seconds Mind you the gas tank is 11 gallons.

Gas pumps varies location to location. I've had same experience. Since that my Durango have 27 gallon tank. It takes average 3 to 4 minutes to fill it up from 1/4th of tank to full (my habit to start filling up gas when it reached 1/4th). Some pumps took me longer than expected. I can feel pump running slowly by holding the hose. Some pump pumps fast. Either that their pump is a bit worn or for safety reason

This is what Hubby told me:

There is a floating device in your gas tank that measures the level of gas. That is what shows up on your dashboard fuel gauge.

Some floats work smoothly. Some floats don't work smoothly, especially as they get older. The smooth ones show the fuel level more quickly

Each gas station pump pumps at different rate. If sometimes you use a pump that fills the tank with more pressure, it might push down harder on the measuring float. Then, it takes a little more time for the float to pop up again. That's what could cause the delay on the gauge.

deafsmogtech · 10-24-2009, 11:05 PM

name of the vehicle manufacturer? what size of the engine do you have?
Modded dashboard's gauges? Dual tanks? No vehicle information given then I dont know. But Reba mentioned about the float of the fuel gauge sender unit, is possiable. Now I ask you one question..... does your truck have a dual tanks? I maybe point at the fuel tank selector switch that was similar to my 1975 Chevy 3/4 ton pick up w/ dual tanks. I experinced with a fuel gauge that showed slow reponse after full tanks when switched the selector to the right tank side. I suspected it was ground circuit problem. I didnt fix it cuz I neglected it for years that not bother me. If you have single tank. I dont know. I feel Reba's comment is a float. The float is made of molded foam, or brass. I dont know exact of what kind of foam that can stand gasoline. Maybe the gasoline blend make a float sink slow? Satured float? I dont know.

On 1991 Mazda 626 (belongs to my friend) I've replaced fuel pump inside gas tank along with float. It's a black plastic rectangular float. Not only Styrofoam or Brass, most are black plastics from what I've seen. Black plastic are designed to withstand type of gasoline or E-85 (E-85 would eats certain type of plastics) .. I would imagine that Styrofoam float would be saturated by gasoline. I doubt it would not prolong in gas tank. I thought Styrofoam tend to 'melt' away in gasoline, Ethanol, and Diesel.. Maybe it's a really cheap kind of float perhaps from Yugo car

yeah that explain, I dunno. I worked at the truck shop long time ago, viewed the RO papers, customer complainted fuel gauge stays at "E" when the tank is full. I figured it out to be a faulty fuel gauge sender in tank. I grabbed my tool cart, rolled out to the vehicle, 1988 Ford E150 van. The shop foreman nosed my RO paper as I was about to dive under the van to get a look at the tank but he took me to go with him to the parts dept, took a brass float from the box and handed me a new brass float. Told me that the brass float in a Ford tank is a history of corroded lead soldered. I learned something to me. I removed a fuel gauge sender from the tank. Realized the brass float was filled with gasoline, caused weight down. Interesting.

Very similar to brass Toilet Ballcock. Lead corroded and water got in and weight the ball down causing water to overflow the tank

That's why Plastics are being used in place.

yeah, same happen to the vintage Rochester carburetor's brass float(s).

I was going to say the same thing.

It can be for a number of reasons. Old gauge. Cold weather. How you're driving. Etc.

Some gas stations give gas very fast. Some give gas slowly.

I can usually tell if I'm trying to get exactly $20 worth of gas. There are a few gas stations where I can't get it to stop at $20 because it pours out too fast no matter how lightly I squeeze the handle.

I guess you don't know how to use it.

Simple, Go to inside build and give $20 cash to casher and said number 5. So gas will auto stop at exactly $20.00 during squeeze the handle.

Be think more hard for next time.

I reach high CFM than low CFM due save my time for business trip. Low CFM is waste of time.

Duh dude... I know how to do that. I'm not really complaining about getting exactly $20. Besides, I used the card-swipe at the pump instead of cash.

Even if I were to use cash, gas stations require people to pay before pumping if paying in cash.

I always use QuickTrip Quickstart card at QuickTrip store so I don't have to go to cashier to pre-pay gas. I just swipe Quickstart card then fill up gas then walked to store and buy slurpee, taquitos and sometime lottery ticket then pay w/ credit card then head out. Quickstart card is for preventing gas drive offs. If you drive off without paying for it, QT store will charge it on your CC that you filled out form previously.

Happen to me once cuz the pump screw up on me and I had to swipe card again then I paid for gas then head out. Next week later, I use same card and it won't work. I went to see cashier and explained the situation. He checked and found out it's the pump problem and there is no gas fee in it so he dropped and let me use Quckstart card again.

The gas stations around here accept credit card and debit card.

Even some of the grocery stores have their own gas stations and offer discounts for their own members (3 to 5 cents off per gallon).

The reason why I use Startcard cuz I can use pump first then go to QT and get something and pay for foods and gas with ATM card (I simply tell them to charge it as a Credit, not Debit). I don't want to have a hassle of walking back and forth to pre-pay the gas.

***sablescort*** · 10-29-2009, 12:04 PM

In all my cars with a trip meter, every time I fill my gas tank, I set my trip odometer to 0 and drive until the gas light goes on. Worked good enough for me esp with my Rodeo's quick to empty gauge because I rely most on the gas tank light and the distance I drove in the SUV. Most of the time light will go on when I reach 380 to 400 miles on the trip meter.

I know cause if my Rodeo's gas gauge says E and I end up fill 17 gallons out of the 20 gallons the Rodeo is supposed to have.

I don't rely on "low gas" warning light. I rely on DTE (Distance to Empty) display on Durango or Jeep's built in ceiling mounted system. This give me time to figure out where's the next gas stop in 20 miles or less. This give me alot of leeway

One time I drove Jeep Liberty and DTE display showing "0" miles and needle was already sitting on "needle stop pin" while I was driving 8 blocks to gas station. It probably running on fumes

Luckily I made it to Gas station before engine pooped out.
