Description:
Genuine OEM replacement Primer Bulb Assembly designed for a variety of Gardening Equipment. This part is sold individually. It includes the Rubber Bulb and the Plastic Body to which hose connect. A primer sends gas into the carburetor so it can create a fuel and air mixture that is ready to go right into the cylinder and keep the engine running. Over time a primer bulb can dry out and crack. If the bulb is damaged it will not create suction and will not function as needed, therefore it will need to be replaced.

Questions & Answers

how to remove the primer bulb from the unit
gilbert for model number hitachi cs40ea
Hi Gilbert, Thank you for your question. Here is some information from our website that you may find helpful in installing the part, "This repair was for a Tanaka/Hitachi blower. 1. Pulled back the carburetor cover by depressing the locking tongue and pinching the sides while retracting. Removed the foam air cleaner. 2. Disconnected the throttle cable from the carburetor. A small metal tip at the cable's end will slide out of the point of attachment to the carburetor. Disconnecting this cable makes it easier to work with the carburetor body. 3. Remove the two screws holding the carburetor body to the engine. 4. You can now remove the two fuel lines from the priming bulb. This may spill some gasoline if you have not run the unit dry prior to the repair. 5. Depress the two tabs locking the priming bulb unit into place and remove the old unit. Pay attention to the nipple orientation of the old unit as one nipple is longer than the other. 6. Install new priming bulb unit with the correct nipple orientation. 7. Reattach fuel lines to the new unit. Forceps are especially handy for this. 8. Reinstall the priming block/choke and carburetor to the engine using the two screws removed in step 3. 9. Clean and replace the air filter. 10. Reinstall carburetor cover. 11. Depress the priming bulb several times to fill and check for leakage." I hope this helps. Thank you and have a great day!
This is on my Hitachi weed eater will this work?

Fuel leaking from the tank
0. Remove the remaining fuel from the tank. Using a funnel I put the fuel back into my 1 gallon gas can.
1. Removed the air cleaner cover.
2. Removed the hardware holding the tank in place.
3. Disconnect the fuel lines at the carburetor and primer, paying close attention to which line goes where.
4. Installed the new vent, return line and fuel line and filter into the new tank.
5. Removed the old primer and installed the new one.
6. Attached the new fuel lines to the correct places on the primer and carburetor.
7. Placed the new tank into position using the mounting bracket and screws attached the tank to the engine.
8. Filled the tank with fuel.
At this point I tried to start the saw, it would not start. I found that I had flooded the carburetor when I was checking the operation of the new primer.(guess I primed it one to many times!) Removed the spark plug then, using compressed air I dried the inside of the cylinder and the spark plug, reassembled and started the saw.
9. Installed the new air cleaner I had purchased and reinstalled the air cleaner cover.
10. Put the saw back to work trimming trees.
