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 (clear) fuel intake line runs from the top of the carburetor (straight nipple) and goes to the short post on the back of the primer bulb. The return line (blue) comes from the long post on the back of the primer bulb and goes into the bottom of the fuel tank.
A single fuel pipe runs from the tank, under the floor of the car to a mechanical pump on the engine. The pump delivers fuel to the carburettor. Whenever you check fuel pipes, disconnect the battery to prevent stray sparks igniting petrol or petrol vapour.
Fuel lines are made of durable metal, plastic materials and though they are located in the undercarriage of the vehicle, and seemingly in a vulnerable position, they are placed in areas that cannot be damaged due to elements, road conditions, or exposure to heat from the engine`s exhaust or other components.
In gasoline cars in U.S., the return line was the fuel flow outlet of a back-pressure regulator on the fuel injector rail on top of the engine. It flowed back into the fuel tank.
there`s the arrow right there that arrow is uh indicating which way your fuel should be flowing. through the fuel filter. so what you want to do is put that arrow. so it`s always pointed at the carburetor.
The Fuel Return Line should be at least the same size, or one size larger than the supply. Make sure there are no sharp bends or kinks. The return line should direct fuel close to the bottom of the tank and away from the pickup.
However, most filters contain an arrow that points in the direction of the fuel flow. For proper installation, this arrow should point towards the carburetor. If there is no arrow on the new filter, Briggs & Stratton recommends placing the larger end towards the engine.
No. A carbureted engine uses a low pressure fuel pump to deliver fuel to the float bowl of the carburetor.
The carburetor is controlled by pressure differences. In the main body of a four-barrel carburetor there are four venturi. The shape, size and length of each help determine airflow and fuel flow into the engine. The term venturi came from its inventor Giovanni Battista Venturi.
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.
Most cars come from the factory with Metal Lines because they hold up better than any soft material. They are usually made from stainless, aluminum or coated steel tube. Metal is the best material for fuel lines.
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.
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.
The fuel line typically consists of rigid metal pipes, with flexible rubber or plastic hoses running from the pipes to the tank and the fuel pump , and from the pump to the carburettor . The flexibility of the hoses allows some movement between these different components.

Poulan chainsaw 18″ 42 cc, pro gas filler cap?
ANSWER : Yep they swell after a while and will not screw in or out!
Sand the threads down so that the circumference is reduced with a course file or plumbers cloth, chamfer the threads a bit on the edges. A new one will do the same thing after a while so just fix the one you have.
