Usually, removing the carburetor should allow sufficient room to work. Good luck!

My prime bulb looses pressure and first start is hard. I have to remove fuel line from filter and cover with thumb prime re install then first start takes time.


Does the engine run fine after it starts? Most common problem with primer bulb losing prime is an air leak in the fuel line or primer bulb. Air leaks don't always leak fuel. If there is an air leak between the primer bulb and gas tank there is no pressure, only vacuum. If it is not a major leak it might not leak without pressure but it will allow air to enter the fuel line. If it is a very minor air leak it could allow air to replace the liquid in the fuel line over time, but so little air once it is primer again that the fuel pump can over come it with volume of fuel.

Primer bulbs do not stay firm, as they are when initially pumped up, after the engine is running. There are check valves in the primer bulb that hold pressure in the primer bulb and throughout the fuel line to the engine. Once the engine starts the fuel pump creates vacuum drawing fuel into the engine diminishing this pressure and releasing the check valves. At this point the primer bulb is just another segment of fuel hose allowing fuel to pass through it as the fuel pump demands. The primer bulb functions much better when the outlet side is higher than the inlet side. This position makes it easier for the check valves in the primer bulb to seat and release as needed. If the primer bulb is functioning properly and is positioned with the outlet side higher than the inlet it should not be necessary to cover the end of the fuel hose with your thumb to get it to prime.

If the engine is hard to start after being fully primed there could be a problem with the fuel system on the engine. Some engines are hard to prime once air has entered the system, especially fuel injected models.

Replaced te fuel lines. no sure Ihavethe lines connected properly


Not sure if your primer bulb is on the carb or separate but here are some basics... The smaller line is the main fuel line. It has the fuel filter on it and the filter should be laying on the bottom of the tank. That line goes to the fuel pump side of the carb ( usually the inlet near the center of the carb body ). The fuel goes through the filter up the main line and fills the carb then to the primer bulb whether its on the carb or separate. If on the carb the spigot closest to the primer bulb takes the larger line and returns to the tank. That line should go into the tank about half an inch and terminate. If the primer is separate the larger line leave the carb from the spigot on the metering side ( usually close to the edge of the carb body) to the inlet of the primer bulb then from the primer bulb out ( usually center of the bulb) to the tank and terminates about half an inch inside the tank. Remember... fuel filter into carb, carb to primer bulb, primer bulb to tank. If the fuel does not go that direction when the bulb is primed then you have lines hooked up backwards.

How to replace fuel lines on homelite ut20811b gas trimmer


If there are two different size lines in the tank the smaller one is the main fuel line. The main fuel line will have the filter on the end of it in the tank and the filter should lay flat on the bottom of the tank. The main line will go directly to the carb on the fuel pump side. It is very difficult to describe and I dont have a way of giving a picture. If you have had the carb opened up the fuel pump side is the side that is mostly flat with holes and the dighram with the flaps.
The other nipple; usually more toward the center of the carb body, will go to the primer bulb. The primer bulb will have 2 different length nipples. The longer one is out to the tank, the shorter one is in from the carb. There is no need to have more than a half inch of line from the primer into the tank. when hooked up properly; as you press and release the primer bulb it will draw fuel up the main fuel line into the carb and fill the carb with fuel then from the carb to the primer bulb and fill the primer bulb with fuel then the excess fuel will be returned to the tank from the primer bulb.

Fuel bulb will not pump


A few things can cause this. Clogged screen in carb and rotten fuel lines are the most common causes. Look inside the fuel tank. If the fuel line is stiff or discolored or if the filter has fallen off its time to replace the fuel lines. Check the fuel pump side of the carb and check the screen to see if its clogged. If the primer bulb is discolored ( any color but clear) its time to replace it. I suggest that if any one of these conditions exist to do it all at once... if the fuel lines are bad then the diaphrams are stiff, etc. Rebuild the carb and replace the fuel lines and primer bulb at the same time.
If you have just had any of the fuel lines off and the primer bulb wont pump then its possible the lines are reversed. If the primer is seperate from the carb; on the primer bulb there are two spigots, one short, and one long. The long one is output and goes to the tank, the short one is input and draws from the carb.

How to replace the fuel primer bulb and fuel lines in McCulloch 3516 chainsaw? the fuel primer bulb broke and the plastic lines have crumbled. i need to know how to run the lines from the fuel tank to...


I just did a primer bulb not too long ago, but I don't remember what equipment it was on. They are generally easy to replace. First, remove anything that is retaining the bulb assembly, such as cover plate. On my Homelite chainsaw, I simply pried it out with a small screwdriver.
The replacement part itself has two barbed stubs that the two fuel line hoses push onto.
Make sure that you keep the fuel line tubes above the fuel level at all times to prevent leakage.

Not getting fuel replaced primer and hoses and not


It's easy to mess this up as I've done it in the past. If the unit has an external purge bulb, the fuel line from the fuel tank that has the fuel filter on it goes directly to the carburetor...near the part of the carb that holds the fuel pump and has the grooved cover (where an inbuilt purge bulb would be). The other line coming out of the fuel tank goes to the purge bulb. The side of the carburetor that has the diaphragm and metering lever cover has the line going to the purge bulb. Remember, this is not really a primer...the purge bulb pulls air and old fuel out of the carb and when it does this, fresh fuel flows into it...and then the bulb pushes that air and old fuel back into the fuel tank. Hope this helps.

  • 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, the output line from the carburetor connects to the suction side of the primer bulb (once bulb is collapsed it draws fuel from the tank through the carburetor to refill the bulb as the bulb refills).
  • The pressure side of the primer returns any excess fuel to the tank as it is depressed.
