It will let air into the tank so the gas will flow better.
If you have a sealed can and try to suck out a fluid, little if any will come out. If you poke a hole in the top of the can every drop will come out. Air replaces the fluid as it comes out. Most newer cars have the pipe hooked to an "Evaporative Canister" (or Charcoal Canister) to absorb the fumes of the gas as it expands and contracts and then the "fumes" are sucked in by the intake manifold to keep the air clean.
Diesel coming out of the tank breather pipe on a 1997 non-turbo diesel van may indicate a few issues. It could be due to overfilling the fuel tank, causing the excess fuel to escape through the breather. Alternatively, a blocked or malfunctioning tank vent can create pressure that forces fuel out. Lastly, a faulty fuel cap or damaged breather hose might also contribute to this problem.
A breather is something you put on your gas tank to let the fumes out. It is the hose coming out of your tank.
yes moisture is introduced thru the breather pipe condensation forms when the tank surfaces are colder than the dew point of the air in the tank
A breather pipe in a ship is a ventilation pipe designed to allow air to enter and exit tanks, such as fuel or ballast tanks, during filling and emptying operations. It helps to prevent vacuum formation and overpressure by equalizing the pressure inside the tank with the external environment. Additionally, breather pipes often include flame screens to reduce the risk of fire or explosion in case of flammable vapors. Proper functioning of breather pipes is essential for safe and efficient ship operations.
i have a 96 bravo and i think the fuel filter is a small black canister under the bonnet located on the left hand side of the motor, there is another larger black canister that is a carbon filter for the fuel tank and has a breather pipe connected to it.
The 'vent valve' is a breather... it has no moving parts... they're typically placed at the top of the fuel tank.
inside the fuel tank
to store fuel
Pipe coming out of the fuel tank
Obviously the tank has to be removed. 4 TIMES 13MM SOCKET BOLTS..REMOVE THEM This drops the tank down. Fuel filler and breather pipe(next to each other)..remove them. Then the fuel delivery/return pipes off the sender. and fuel gauge wire off the sender. pull the tank out and the sender just screws out. Money saved on repairs can then be wasted in the pub or betting shop...;)
in most(all)vheicles gas tank breather runs side to side with fuel tank hose(where you put the gas nozzle when filling up ) look for a small hole under the area where the gas nuzzle goes usually that is the (gas thank breather)
easy way is to drill a 1/16 hole in the middle of your gas cap
