SOURCE: Primer bulb not filling

Yes, I think the gas cap may be clogged. The gas cap must be able to breath, otherwise this vacuum will occur. Try starting your trimmer and when it starts to choke out, loosen the gas cap. It should get air back in the tank, then and keep running. If this works, clear the hole in the gas cap, or purchase a new one.

SOURCE: primer bulb only holds suction, wont move fuel thru line

By "holds suction" this means that you can depress the primer bulb and it remains in the "pressed" position and/or does not reinflate (for lack of a better term)?

You need to determine if a blockage exists in either one of the fuel lines, or with the primer bulb itself.

First, drain your fuel tank. Do this into a clear mason jar or equivalent and inspect your fuel to see if it is full of debris since even very small pieces of grass, dust, dirt, etc... can cause problems. If so, then you need to flush your fuel tank and or lines.

Viewing the backside of the primer bulb, you can see several clear fuel tubing lines that lead from the primer to the carbureator and fuel tank..

Next, carefully remove these using a pair of needle nosed pliers (or by hand is at all possible) being very careful not to crush or tear the tubing.

With the clear tubing removed, if the primer bulb will press in and immediately reinflates back to it's relaxed position, then one or more of your lines are clogged by a small piece of debris. If the primer still does not relax, then it is blocked by a small piece of debris or needs to be replaced (pick one up at Lowes, etc...).

If you determine that your lines may be clogged, then I have had success clearing them with a can of WD-40 by sticking the red nozzle into the clear tubing (attempt to make a seal) and by pressing for a half-second or so. If you get flow, then let it rip for a second, then proceed to rinse your fuel tank again just for good measure (basically until you get nothing but clean gas...no debris).

Put it all back together and let it rip!

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.

No fuel in primer bulb on my echo PB 2100 blower


The primer bulb pulls fuel from the carb into the bulb and dumps back to the tank, so either the tubes are not connected too the correct conections on the carb, or there is bno fuel getting to the carb from the tank ( fuel filter ) or if the primer is on the carb itself there in a red one way valve under the bulb which maybe faulty.

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.
