Fuel line pipes and hoses carry fuel from the tank to the engine. The main fuel line pipe allows the fuel pump to extract fuel from the tank. The fuel is fed through the pipe to the pump and then to the metering portion of the carburetor or injection system. The following article shall tell you more about fuel line pipes.
Here are the main points of the article:
What are the rules to remember when working with faulty fuel line pipes?
What are fuel line pipes mainly made of?
What is fuel pump volume of the fuel line pipes?
Defective fuel line pipes and hoses are a common source of fuel leaks. Fuel hoses become hard and brittle when exposed to the heat and elements of the engine. The oil will soften and swell them. Inspect hoses often and replace any hoses that are in poor condition. Metal fuel pipelines rarely cause problems; However, if they become crumbled, kinked, rusted or leaky, they should be replaced. When using fuel line pipes and hoses, remember the following rule: when disassembling, place a rag around the fuel line fitting. This action prevents the fuel from gushing to you or the hot engine. Use locknut or tubing wrench on tubing connector. Use only approved double wall steel tube fuel line pipes. Do not use copper or plastic tubing. When forming a new fuel line pipe, make a smooth bend. Use a bending spring or a bending tool. A double - ring flare is formed at the end of the fuel line. A single torch is not allowed to be used in fuel piping. Reinstall fuel line pipe clamp and bracket. Without proper support, fuel lines may vibrate and fail.
Fuel line pipes are usually made of double-walled steel tubes. For fire safety, the fuel line pipe must be able to withstand the continuous violent vibration caused by the engine and the road surface. Piping is kept away from the exhaust pipe, muffler, and manifold so that overheating does not cause a gland seal. They are mounted on frames, engines and other components so that the impact of vibration is minimized. Fuel hoses are made of synthetic rubber and are used in places where there is intense movement between parts. Flexible hoses can absorb motion without breaking. Hose clamps are needed to secure fuel hose to fuel line or metal fitting.
Fuel pump capacity refers to the amount of fuel that can be transported by the fuel line pipes and the fuel pump in a certain period of time. It is measured by allowing fuel to be poured into a graduated (marked) container for a certain amount of time (usually 30 seconds). Connect the output pipe of the fuel pump to the measuring vessel. For safety purposes, a valve or clamp should be installed to control the flow of fuel into the container. When the engine is idling at a set speed, allow the fuel to be poured into the tank for a set amount of time. Close the clamp or valve and compare the volume output with the specification. For carburetor systems, the output should be at least 1 pint in 30 seconds. The fuel injection system has a slightly higher output from the supply pump. Always refer to the instructions for specific fuel pumps and vehicles. If the fuel pump pressure and volume test are not qualified, the fuel pump vacuum should be checked.
