Look at the hoses... Look for dirt marks or indentations or bends the way they are molded that match the closet solid piece to it...

Fuel tank vent hose routing on a husqvarna 353 without the primer bulb


The early 353 had a breather made up of two small,round white tablets that just pushed into the tank, the later breather was a white plug with a hose connection on the outside, there was nothing on this connection, the pro saw 346XP had a pipe on the connection which came up through the crankcase floor along side the fuel hose and pushed onto a hose connection to the r/h side of the carb.

Did they really change your oil filter?


Want to be sure? Before you bring the car in for an oil change, use a black magic marker on a white filter or a white paint maker on a dark colored filter. Make a mark you will recognize.
Before you leave the premises with your new oil change take a peek. Many times you will see your marked filter still on the car. Show the mechanic what he did not do. I can assure you he will humbly change it, saying he told another mechanic in the shop to change it but that guy must have forgot.

How do I change the fuel lines on a 445 husqvarna chain saw


There are two hoses coming from the r/h side of the tank, one is the main fuel line ( with the fuel filter on the end inside the tank ) and the fuel return tube which comes down from the primer bulb, there is also a white tank breather valve next to these pipe ( make sure the fuel is not leaking from here ) both hoses are moulded and push into the tank, it should be just about possible to do this without removing the tank, however it is much easier to remove the tank.

Model 331877 briggs fuel pump leaks oil out vent


I just got done repairing the very same engine with the same syptoms that you mentioned. I had considerable oil coming out of the fuel pump breather hole (copper colored mesh). The source of the problem: a blown head gasket. This will cause the piston, in the compression cycle, to pressurize the crankcase through the head gasket leak into the valve lifter chamber and push oil out the vacuum tube (bottom hose) leading to the fuel filter . To fix, you will need to first disassemble the cylinder head from the engine. To do that you first need to disconnect the three hoses to the fuel pump. Remove the cover to the air filter, remove the air filter and the screw in the bottom of the filter housing. Remove the four bolts attaching the plastic flywheel cover and remove the cover., remove the cylinder head (8 bolts)and check the head gasket to confirm it is blown (you will probably see some dark brown or black discoloration of the head gasket between the cylinder and valve lifter chamber. Carefully remove all old head gasket material from the block and head surfaces and clean the head bolts. If either your cylinder head or block surface looks ugly, you may need to get them resurfaced (flatness tolerance is very small ) Buy a valve gasket set (contains the head gasket and other needed parts)
Remove the valve rocker arm cover (4 bolts) from the head. Mark the exhaust and intake lifter rods (they are different) Clean the combustion chamber. If your engine has many hours on it, you will want to remove the valves and check the valve rims and seats for wear or pitting. You may want to hand lap the valves to insure they are seating perfectly.
I coated my head bolts with an anti-sieze valve lube compound. The B&S service manual calls for this. Reassemble head and torque head bolts to 220 in.-lbs. (4 stages) Do very accurately. Compress valve springs, install push rods and set clearances between rocker arm and end of valve stem. Turn flywheel to move piston so that both valves are closed before setting clearances. install a new fuel pump on the plastic flywheel housing. I removed the breather from the top of the engine (two small screws) and checked the reed and oil drain hole, and resealed the breather cover (you will need to pull the flywheel to get to one of the breather screws. I used a gray high-temp rtv liquid gasket compound to reseal the rocker arm cover and breather body. Reassemble all parts and screws and use small torques as listed in Briggs Service manual. I put in a new spark plug, changed the oil and filter, and breather tube, and o-ring at the bottom of my oil filler tube. That should do it

I filled my 340 husqvarna chainsaw for the first time this year and it leaked gas from someshere opposite the fuel fill tank( maybe near the fuel line). It then quit leaking and just will not start. Maybe...


Opposite the fuel fill is the tank breather, and the return to tank hose if the machine has a primer, the back to tank hose fits on to an orange connection in the tank, it may have slipped off, next to it is the breather the early breather was two white pellets pressed into the tank, these will need to be removed and replaced if this is where the leak is from, the later breather is a white round assembly with a connection on the top, nothing fits to this conection, the breather can be pulled and and replaced if required.

Oil is coming out of the air beather


This is a common problem. Now the heading says your bike is a 1979 Sportster. Regardless of what it is, there is a crankcase breather that is routed to your air cleaner. This was done to satisfy the EPA regulation that crankcase fumes must be run through the engine to be burned. With the crankcase air come a mist of oil. This oil builds up in the air breather and runs out. You have to clean the air filter out periodically. You can find the crankcase breather hose and re-route it somewhere else so the oil won't go into the air filter.

Good Luck

Oil system manual for a 1987 softail (evolution). oil leaking from breather of engine system.


On your '87 Softail, the engine breather vent is behind and below the oil pump. The air from the breather is routed into the engine air filter by a metal pipe and rubber tubing that runs from the breather vent to the air filter. It is common to get a bit of oil in the air filter because of this system. The system was designed to meet EPA regulations of the time. Since then, the breather system has been modified to allow the engine to breathe at the top of the heads instead of down low on the engine. This resolves some of the problem with oil getting into the air filter but it still does not eliminate it. The only way to eliminate the oil from getting into the air filter is to reroute the air from the crankcase breather vent to somewhere else. Most people just let it exhaust underneath the bike by putting a small breather filter on the end of a short piece of rubber hose connected to the breather vent.

Good Luck

Oil leak out of a breather hose


a small amount of oil from the crankcase vent hose under hard acceleration is most likely normal.American bikes don't leak oil,they mark their spot!

Have oil coming out of the air filter


You may be running too high an oil level. If the problem persists, unplug the breather hose from the air cleaner and route it down so the oil goes to the ground, better yet (and too avoid getting leaked oil on your back tire) buy a small filter and attach it to the end of the breather hose. Most likely the engine oil level is too high though.

2004 honda crf 150 and all of the hoses are off of carb.?


Not positive but on two stroke bikes all but one of your hoses are breather and over flow hoses and are smaller than the fuel line that should come from the front left of the carb and go up to the fuel tank. the rest should come from the carb and have holders attached to the carb feed the line closest to the holder and fit it on the breather hole coming from the carb pertruding outward from the carb. there should be three or four lines and one fuel line.
