Calculating Fuel Tank Capacity

If you`re curious about your fuel tank capacity, here is a simple formula to determine the size of your gas tank in gallons. Simply multiply the length, width, and height (L x W x H) of the gas tank, then divide the total by 231.

Introduction. A fuel tank in the vehicle is an important component of the fuel system in an internal combustion engine. A tank is used to store motor fuel such as petrol, diesel fuel and gas. The present-day fuel tanks can be made of different advanced materials: ferroalloys, aluminum alloys, plastics.
Automotive fuel tanks

A larger fuel-tank results in a greater range for the car between refills, however the weight and space requirements of a larger tank are undesirable, especially in smaller cars. The average fuel tank capacity for cars is 50–60 L (12–16 US gal).

Average Sizes of Fuel Tanks: The tank is the part of your car`s engine system containing flammable fuel such as gasoline and oil. The average tank can carry between 45 to 65 liters of fuel.
Unfortunately, there is no clear answer as both plastic and steel tanks have advantages and disadvantages, personally, we believe polyethylene fuel tanks are the better choice as they are cleaner, lighter, condensate less and last as long as a steel tank.
if it is 2/5 full, it is 3/5 empty. 1/5 = 10/2 = 5 litres, 5/5 is full so 5 x 5 = 25 litres. At full capacity the car petrol tank is 25 litres.
This means that a litre of 95 Unleaded petrol will now set you back by R22. 30 at the coast and R22. 95 in Gauteng and other inland regions, where 93 Unleaded will now cost R22. 65.
The size of your car will determine your gas tank size. A small car can normally hold roughly 12 gallons of gas. A larger car can hold up to 15 gallons of gas and, in some cases, even more.
The most common types of storage tanks used to store liquids are as follows: Fixed-roof tanks. External floating roof tanks. Internal floating roof tanks.
The T-54/55 series is the most-produced tank in history.

In this case it is important to keep the center of gravity as low as possible, therefore the best solution would be n. 1 Elliptical shape.

Yes, even the inside can rust, but what happens most times is that the tank will degrade on the bottom where the sludge, moisture, and water gather in the tank. And on the bottom edges at the seams are typically the first place the tank will start getting holes.
One US gallon is equal to 3.785411784 liter.
The tank cannon has a maximum effective range of about 3000 meters, and precise aim is required to make a hit.
V(tank) = (πr2 + 2ra)l

The filled volume is exactly 1/2 of the cylinder portion plus the volume of fill inside the rectangular portion. We calculate fill volume using the circular segment method, as in a Horizontal Cylinder Tank, for the empty portion.

1.0-1.2 Litre Engines

You`ll get a good fuel economy out of them, as the smaller capacity means less fuel is used. This is great if you mainly do a lot of stop/start driving, such as in a city where there are lots of traffic lights, or if you usually make short journeys.

A fuel level sensor (FLS) is used in all automobiles to indicate fuel level. Various methods are used to measure fuel level such as resistive film, discrete resistors, capacitive, and ultrasonic. Resistive-based sensors are most commonly used for this application.
For a cylindrical tank with the base radius r = 4 cm and the height h = 7 cm, we can calculate its surface area like so: A = 2πr(r + h)

Size for 12 Hour Run Time = Fuel Consumption x 12 hours x 1.1. Min. Size for 8 Hour Run Time = Fuel Consumption x 8 hours x 1.1. Actual Tank Runtime = Actual Tank Size x 0.9 ÷ Fuel Consumption.

I have a husqvarna 323L string trimmer. I stored it after running the tank & carb dry for about two years. I fueled it, then started it, & it ran for a minute then died like I turned the switch off. Since it would not restart, I found the fuel filter had broken off the hardened fuel line & it sucked gummy crap out of the tank & into the carb. Failing at cleaning the carb, I finally put a new carb on it & replaced the pump, hoses & filter. It has ran good till this year. I winterized it with stabilizer & left it with a full tank over the winter. The gas in the tank was gone when I got ready to use it this year. I filled the tank with premix, checked for leaks, then started it. It would run fine for about half a tank, start idling poorly (lean) then cutoff & refuse to restart till I refilled the tank. I finally found the tank had cracks & was letting pressure out of the tank & apparently this was causing the carb to lose it’s ability to siphon gas out of the tank. So I replaced the tank which came with new hoses & a filter, which I properly installed to the carb. It cranked right up, but when it runs a half tank, the carb quits sucking gas out of the tank. When I pump to prime the carb, it moves the fuel into the carb, but the pump never gets hard like it does when I prime the carb when the motor is cold. I have to keep refilling the tank, prime, & then it starts & runs until the tank gets about half empty. The new fuel filter is down in the gas tank properly, but It will not run after it shuts off until I refill the tank & prime. I’m baffled. New tank, new hoses, new filter, new carb, & I can find no leaks in the fuel system. It runs strong. The 323L is a two-stroke & it always cranks on the second pull from cold on a full tank. Any ideas?

How do you get the fuel line connected to the fuel filter nipple on the bottom side of the gas tank on the Ryobi 725r gas trimmer?
ANSWER : You must run the fuel line through the back of the tank and out the filler hole,make your connections,i used a small amount of vaseline to make the connections.Then pull the filter into place,make sure some of the nipple of the filter pokes through,then slide the retainer ring on the hose and force it onto the filter nipple.

Have a craftsman 16″ chain saw 358.360260. Could not initially get it started after it had sat for a couple years with fuel stabilizer in it. When I went to use it the fuel had all evaporated and the fuel pick line was rotted. I replaced that with some difficulty but finally got it on. Saw still wouldn’t start. Replaced the fuel filter. Still wouldn’t start. Pulled the carb apart and cleaned and recleaned everything. Diaphragms were good and I didn’t adjust any of the mixture screws because as I said it ran fine before storage. Non of the carb passages were clogged. Fresh gas 40:1, good spark plug and good spark. Airfilter is good. Engine has maybe about 4 hours of total run time on it. It’s a ZAMA (?) carb. It will run for about 30 seconds when I manually prime it by pouring a small amount of fuel directly though the carb. When I was disassembling the carb the vent hose that goes back into the fuel tank seemed to have a small out of ?substance? in it which I cleaned out. It was right at the end the of the hose that goes back into the fuel tank and not up by the carb. It didn’t appear to be like your typical gummy deposits/varnish though. I hope it wasn?t some type of spongy check valve stuff that is supposed to be in there. That might explain some of my problems. Anyway, I also can not seem to get the primer bulb to fill. When I open the fuel tank, look in side and depress the primer bulb, air bubbles come out of the fuel filter. But when I let the bulb reexpand there’s no fuel that gets sucked up the hose. I can however seem to fill the primer bulb when the fuel tank is full and the chainsaw is laying on it?s pull cord side and the bulb is depressed a bunch of times. The saw will also start and run again for about 15 seconds then die. It’s definitely not getting/fuel and probably running out . Thanks.

I have a craftsman 25 cc string trimmer with fuel problems. After winter, ran tank of good fuel through it and it worked fine. Added fuel (unknowingly with water in it) and it ran on a slow idle and finally died. Drained fuel, took carb apart and cleaned, blowed out carb and reassembled. Still only ran on a slow idle – no throttle response. Took cover off with air cleaner and it ran fine. Seems to blow too much fuel out where filter sits. Put filter back on and runs on slow idle. Almost seems it is flooding, but have not adjusted anything, just cleaned. What do I need to do next?
ANSWER : You shouldn’t notice a difference if you remove the air filter. So I would replace it. Also if you are using compressed air to clean or blow-out the carb. Be careful, its not recommended and could make it worse.

I need a diagram for the fuel lines on a ryobi 31cc trimmer plus 15″ from the fuel tank thru the primmer bulb to the carb for both lines
ANSWER : Don’t quite understand your dilemma… there are only two fuel lines which go from the tank to the carburetor…..if looking at the engine from the back, the fuel line on the left is the intake line and the one on the right is the fuel return line….on the back of the carb are two fuel line brass inserts…they are inlet on left and return on the right….hope this helps ;-D
