How do you replace a fuel line in a tank when the exit hole is smaller than the fuel line?

How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

The yellow fuel line is 3/32-inch ID x 3/16-inch OD x one foot long and the blue fuel line is 1/16-inch ID x 1/8-inch OD x one foot long. The fuel line fits Blowers, Chainsaws, Trimmers and other gas-powered equipment that use this size fuel line.
Most chainsaws have two fuel lines – one that feeds fuel into the carburetor and a return tube that allows unused fuel to flow back into the chainsaw gas tank.
Most vehicles have rubber fuel hoses connecting the fuel pipes on the chassis to the fuel pump or carburetor on the engine. Rubber hoses are flexible and can be cut to length as required, but they have a tendency to perish over time and can rub through if not properly secured.
NOTE: IF A HOSE DOESN`T HAVE A SAE J30- STANDARD ON THE SIDE, DON`T INSTALL IT IN A FUEL SYSTEM. SAE 30R6 hoses are designed for low-pressure applications like carburetors. These can also be used as an emissions hose. SAE 30R7 hoses are designed for fuel.
Most modern chainsaws, string trimmers, leaf blowers and other small-engine two-stroke equipment recommend a 50:1 oil mix ratio, but some recommend 40:1 and older two-stroke equipment might even call for 32:1.
Metal Lines

They are usually made from stainless, aluminum or coated steel tube. Metal is the best material for fuel lines.

Add a small amount of fuel stabilizer to stored fuel and your lawn mower, snowblower, rototiller, chainsaw, generator and vehicle will start easier and run better. Fail to use fuel stabilizer can mean poor performance or an engine that fails to start at all after several months of storage.
Most STIHL gasoline-powered equipment runs on a 50:1 mixture of gasoline and 2-cycle engine oil. Knowing the proper way to mix your fuel is the first step in keeping it running strong and long.
Material: Metal fuel lines are made from materials such as steel or aluminum, while rubber fuel lines are made from rubber or other elastomeric materials. Braided fuel lines are typically made from a metal or synthetic fiber braid that is wrapped around a rubber or other elastomeric core.
Leaks can be caused by corrosion in steel pipes, and cracks and abrasion in all types. The clips holding the pipe to the chassis may damage it, or they may rust and fall off so that the pipe becomes loose.
Fuel piping inside buildings is typically carbon steel piping. Regulations prohibit pipe materials such as plastics that would have a relatively low failure temperature in the event of a fire. Schedule 40 carbon steel black pipe is typical for primary piping.
Required fuel pressure can vary depending on your vehicle`s engine and fuel system. Carbureted engines may require as little as 28 kPa (4 PSI), while modern multipoint fuel injected high-performance engines can require as much as 414 kPa (60 PSI).
It`s hard to deny that rubber hose is still a popular choice for many homebuilt fuel systems. It is relatively inexpensive and very easy to install. Compared to other options such as rigid aluminum tubing, it has one major shortcoming: It has limited life and cannot be considered a permanent part of the airframe.
50 to1 means 50 parts of gas to 1 part of oil. So the 40 to 1 mixture is more oily and provides better lubrication for your piston rings. The downside is it will foul out your spark plug sooner, but that`s no big deal because it`s simple to pull the plug out and clean it and stick it back in.
For a 50:1 ratio of gas to oil, use 2.6 fluid ounces of oil per gallon of gas. For a 40:1 mixture, use 3.2 fluid ounces of oil per gallon of gas.
Polytetrafluoroethylene also has less surface friction than rubber, which means that flow can be improved by using PTFE hoses. While rubber is prone to break down at extreme temperatures, PTFE is highly temperature resistant, making it ideal for all kinds of industries.
Braided lines are stiffer than rubber lines and are more durable. Add the proper hose ends to the tubing if you buy a roll of it. You could also purchase braided hose to fit specific applications. Braided hose provides better heat dissipation and better flow, which is important when choosing performance car parts.
Aluminum tubing can be used for everything from fuel, transmission, and oil supply lines, even vacuum and coolant lines. Aluminum tubing should never be used for pressurized brake lines.
Every fuel line experiences pressure loss depending on fuel line length, and fuel flow rate.
Does size really matter when it comes to fuel lines? According to the fuel delivery system experts at Fuelab, it does. It`s because fuel line size and length have a direct effect on the amount of fuel pressure drop your fuel system will experience.
Each time the car cranks and runs, the fuel hoses will have transport the fuel to the combustion chamber. These hoses can last anywhere from 10,000 to 50,000 miles depending on what they are made of.
Yes. We paint all piping (inside and out) to protect them from rust and corrosion. We also think it looks more professional than unpainted steel pipe!
Clean the gas pump, fuel lines and injectors by adding cleaner to the gas and running the engine. Add a second cleaner directly to the warm engine to remove gunk and carbon deposits from the combustion chambers.
Using a fuel line disconnect tool helps you disconnect the fuel line from the connector without causing damage. The tools put the right amount of pressure on the connection to disconnect with minimal effort on your part. Many fuel lines only disconnect using the specialty tool.

The fuel lines have rotted out of the edger gas tank. How do I fix or do I need to replace entire tank with new fuel lines?Since there are no male fuel line connections exiting the fuel tank and just two holes where the lines were, I guess I need to replace the entire tank and get a new one with lines already attached. Thanks.
ANSWER : No you can buy replacement fuel line but you must reconnect the filter in the tank that line goes to the bottom of the carby then out the top of the carby to the inlet on the primer then out of the primer and back to the tank.

Need to replace fuel lines on my Troy Bilt gas hedge trimmer. Where can I get replacement fuel lines… or better yet… what size are the lines and where can I buy a few feet of the lines. Note: I have reviewed the parts assembly and it would seem to indicate I have to replace the entire handle assembly (Part #1) instead of just buying replacement hose(s). Any help to resolve my issue would be greatly appreciated and thanks in advance
ANSWER : Replacement fuel lines should be readily available at your local lawnmower repair shop. Your TroyBilt hedger uses fuel line that is 3/32″ (2.4mm) interior dimension, 3/16″ (4.8mm) outside dimension, with a 3/64″ (1.2mm) wall dimension.
Most manufacturers don’t offer replacement line, only fuel tank assemblies. Find your local shop, and try to get the TYGON brand…it is yellow. Tygon lasts the longest. You should be able to buy it by the foot for less than $2 per foot. You will need 2 feet of hose to replace both lines.

Make sure to clean the in-tank filter when replacing hoses.

Good luck.

Replaceing fuel line in polan 3300 chain saw – Poulan Pro 42CC 2 Cycle Chainsaw, 18"
ANSWER : Hi owjbhend…
Use a piece of wire and insert it into the fuel line, then bend a hook in the end and hook it over the end of the fuel line…lubricate the fuel line with some vaseoline very lightly…about the first one inch of the fuel line and then use your fingers to start the fuel line into the tank, once you have the fuel line in the tank give enough to hook the fuel filter to and so it can be dropped back into the tank.
Below is a drawing of how to route the fuel lines.

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?

I need to replace to fuel lines on a Craftman 32cc trimmer. The old ones cracked apart. 2 of the lines look like 1/8″ OD one line looks like 3/32″ OD. Larger line looks like it hooks to filter, Smaller line to a fitting in the gas tank. I am assuming the smaller line ges to the primer inlet. My question is the lines penetrate the bottom of the gas tank. How do they seal. How do I install the filter and the fitting. I am assuming to thread the new lines in from the bottom of the tank and pull through the gas cap hole. Then I attach filter or fitting and pull back through. So do I pull the line so as to create a seal from the swell caused by the fitting/filter?
ANSWER : Depending on the brand of line you use, Tygon line is self sealing but seems to shrink faster then factory supplied because of the ethanol in the gas. The stone gas filter is designed to fall to the lowest part of the tank, not stop the line from falling out.

The saw starts up fine, runs fine but not for long. it runs for about 1 minute and dies. like it is out of fuel or sucking air, i noticed there is no filter on the suction line and there is another nipple entering the fuel tank which appears to need a hose on it , is this just a return line, or should the long line in side the tank press on to this nipple? thanks,
ANSWER : I’ve had my pp4218 for about 2 years and the fuel lines have rotted. I’m thinging from ethanol in the gas. However, I’m replacing them and cannot tell which lines go where. Does the large line from the bubble go to the filter and the little line return?
