I changed the primer bulb on my echo srm-210 trimmer but it will not prime fuel in the bulb. The grummet the three lines go thru on the gas tank is not sealing the lines tight. Is this the cause?

If there is adequate fuel in the tank to completely cover the fuel filter than I expect the bulb to pull the fuel through the carburetor.

If you are able to determine the fuel intake hose (the hose that connects to the filter in the tank) to the carburetor than removing the hose from the carburetor and close off the inlet connection to the carburetor with your finger,

You should be able to achieve a vacuum that as you stroke the bulb that it eventually stays down and will only return the to the normal position when you release your finger from the carburetor inlet hose connection. This will leak check the bulb and carburetor. If this is successful drawing a vacuum than there is most likely a leak in the hose between the filter in the tank and from where you had disconnected the hose from the carburetor. Lowes and home depot provide a kit with a wire that snakes through the grommet allowing for this hose to be replaced..

If you cannot achieve a vacuum than the one way valves in the bulb prime are defective or an air leak through a check valve, metering diaphragm or fuel pump. A carburetor repair/replacement is likely

Smelling gas. Is that a vacuum hose leak?

The first place to look for a leak in these new cars is the fuel tank vent hose or the fuel injection line. Older cars, pre-1980's, have a carburetor float bowl. When you shut off a pre-1980 car there is normally some boiled fuel that will create a smell of gas.

Replace fuel line in husqvarna 141 chain saw

The fuel line on the 141 is very small and wasn't really meant to be replaced for some reason, as it is a pinch fit. Buy the smallest fuel line you can, usually 1/8th OD inch fuel line. Remove the air-filter and the carburetor. You will need to drill out the
current hole a little bit, so go slowly. As soon as the new fuel line will fit _tightly_ insert the line. You will have to remove the hand-bar and the
anti-vibration bolts to separate the motor mount portion from the gas tank which is part of the hand grip.

Apply some gasoline proof gasket sealant to the space between the gap, else you will have a gas leak from the tank sooner or later.

Reassemble the grip and motor sections back together and let the sealant dry for a day or so. Put the carb and air filter back on and attach the fuel line to the carb and the other end to the fuel filter in the gas tank.

Tried to repair a gas leak under car . we tried to repair the hose now it doesnt leak from above the hose only under and used 2 clamps and it is tight as we are able to get it is it the metal piping ?

you don`t say what type of fuel system you have,carburetor or fuel injection,throttle body or port fuel injection system.this determines the type of repair.if it is port fuel injection then you cannot repair with a hose,it must be repaired with a steel line as the fuel pressure is above 30lbs pressure and rubber hose is not strong enough for the can replace the section of line that is bad with a new steel line connected to a good section.if it`s carburetor the pressure is only about 6 to 8lbs pressure,and a hose can make the repair.if it`s throttle body then the pressure can range anywhere from 15 to about 20lbs pressure,this can be repaired with fuel injection gas hose,so you can see it makes a difference what system you have.any rubber hose used must be a fuel line hose not just any rubber hose.

Honda 250 seems to be leaking gas from somewhere.smells really strong of gas fumes in my gararge.don't know where to start looking?

fuel leak best to start at the tank check around the tank seems for gas residue check you fuel petcock for leaks fuel line leak,carburetor for leaks.
if there is nothing you find externally you may have a stuck float or bad needle seat allowing fuel to seep into the engine cylinders and into the exhaust pipe.

My 06 venture is leaking fuel from under the tank on left side about in line with the rear carbs, havent looked under there and fuel dosent hit the ground or heads

There's a fuel block under the tank that splits the single output from the petcock to four lines to the carburetors; a cracked or broken line or a damaged block could be the source of the leak. There's also a fuel level sensor on the underside of the tank that can leak and cause the same problem. A cheap diagnostic tool might show you the source of the leak:
mix powdered clothes detergent with water until it's a thin paste, add red (or any other bright color) food coloring to the paste, paint paste all over areas that may cause the leak (in this case, you'd paint all the fuel lines to the carburetors, and the entire underside of the tank). Drive until leaking gas is noted, check for missing colored paste.

Should I leave a small peice of fuel line in the gas tank ?

Hi and welcome to FixYa, I am Kelly.

Ok.. We need your help here. I understand your going to replace a fuel line. Depending on what make and model your doing the fuel line replacement on the procedures are different. Some connect to the tank outlet. Some connect to the fuel tank screen pick up
others connect to a fuel shut off valve. They all end at the carburetor.

If you do a like part replacement the only thing you have to be concerned with is that it does not leak after you install the new line. What is most important is that you make sure to clamp both connecting ends of the new line. Fuel lines rapidly get hard and will leak causing the possibility of a fire during use / personal injury. I have repaired numerous BURNED units that early in the mowing season the owner had replaced the fuel line and by July or August it caught fire because they did not install the clamps or the right clamp when they replaced the fuel line. It isn't a difficult task.

Thanks for using FixYa.


(If you need more details I need a make and Model number to be of any further assistance to you.)

Husqvarna 350 chain saw will only start if I manually put gas in the carb. and then it dies! I've clean the carb twice! The piston ring is within specs and the muffler is not dirty.

Typical fuel system:

Fuel Line Replacement by
  • The hose in the tank with the filter on the free end connects directly to the carburetor input connection.
  • If the saw is equipped with a primer bulb, an output line from the carburetor connects to the suction side of the primer (once the bulb is collapsed it draws fuel from the tank through the carburetor to refill as it inflates).
  • The pressure side of the primer returns displaced fuel to the tank as it is depressed.
Take lots of notes and a few digital photographs to help with reassembly. It can also be an air leak, inspect for a loose or defective carburetor manifold or loose carburetor. If those are good then the likely cause is internal parts of the carburetor are dirty or have failed. HTH

I have an older Weed Eater gas powered trimmer(Model XT 85T) The fuel lines have aged, rotted and broke. I have new lines (big fuel line and small fuel line). How do I get these lines through the holes...

gas line is 1/8" ID. NAPA autoparts sells replacement gas line that works but has an OD that will not fit hole in plastic frame where the carb sits. Just drill the plastic to the OD of new gas line and use needlenose pliers to install the line. Same goes for the gas tank. Just make sure it is tight fit so it does not leak.
