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: I am replacing the fuel tank assy and purge bulb

The order of fuel travel should be:
Fuel filter to fuel hose to Carb's Fuel Supply nipple. (On the main body of the carb)
Primer Plate Nipple on carb to fuel hose to Suction Nipple on Primer Bulb. (It must pull fuel thru the carb, not push)
Pressure Nipple on Primer Bulb to fuel hose to Fuel Tank Return hose.

When correctly installed, the fuel will be PRESSED into the fuel tank via the return hose when primer is pressed in . . . and SUCTIONED out of the tank and into the Carburetor when primer in released.

Hope this helps,

I have a WEEDEATER XT125.I don't remember how the fuel lines from gas tank are routed to the primmer bulb and from there to the carb. HELP??/


the fuel line from the tank with the fuel filter on it goes to the inlet port of the carburetor then the inlet hose of the primer bulb goes to the outlet of the carburetor and the last hose goes from the outlet of the primer back to the fuel tank

generally you have 1 line from the tank that has a fuel filter attached to it that goes to the inlet port on the carb, 1 line from the carb to the primer bulb, and 1 line from the primer bulb back to the tank. when you press the primer it draws fuel through the carb and returns it to the tank through the primer bulb

Wont prime up


I have seen a couple of different things cause this... Are the fuel lines hooked up and not split and fuel filter routed right in tank.(hanging freely touching bottom of tank lying flat) next if your carb has adj. screws H &L I have seen when the H is cranked snug (lean) that primer won't work right. Last but not least your Needle inlet valve is stuck shut and or the fuel pump diaphram little tabs are not sealing off chambers in carb on fuel pump side. make sure your fuel lines are properly hooked up to the right spots. when you push primer bulb it should squirt gas into the fuel tank, then when you release it ,it should draw fuel from the tank through the filter and thru the carb and then out to tank.

No gas getting from the gas tank to the carb. replaced hoses and filter already. can not even draw gas with primer button.


You either need a new primer bulb (leaking air) or you have the fuel lines routed wrong. Here is the correct fuel line routing just in case:
Small diameter line out of fuel tank (has filter in-tank on end) connects to the side of the carburetor that has the fuel pump....that is the cover without the hole in it. Other larger diameter fuel line out of tank connects to the longer nipple on the external purge/primer bulb. The bulb "pulls" fresh fuel from the fuel tank to the carb and then out of the carb to itself, where it then pushes any air/old fuel back into the fuel tank. The remaining larger diameter fuel line in this setup goes from the metering chamber (has cover with writing on it and a vent-hole) side of the carburetor to the smaller nipple on the purge/primer bulb. Again, on the primer bulb, the longer nipple has a line going directly from it to the tank. The shorter nipple on the bub has a line from it going to the metering chamber side of the carb.If the purge/primer bulb is on top of the carb...small line from carb body to small hole in tank with filter. Larger diameter line goes from the bulb on the fuel pump side of the carb to the larger hole in the fuel tank where the line is held in place with a nylon nipple connector that keeps the line from pulling out of the tank

Need to know how to connect the gas lines from the primer bulb to the carburetor on a poulan woodshark model 1950 chainsaw


The lines should be connected to push fuel into the carburetor. The output (overflow) of the carb is routed back into the tank. So, two lines in the tank, one is an overflow (return) and the other is the suction. On the primer one line from the tank and the other to the carb. Connect so as to "push" fuel into the carb when the primer bulb is pushed.

Replaced gas tank and primer bulb on my Poulan Leafblower FL1500 and it appears I'm not getting gas into the carb. Any ideas as to what my be the cause?


I assume the new tank came with new fuel lines and filter in it.
First be sure you have all the lines hooked up correctly. There should be a main line from the tank ( has the fuel line on the end of it in the tank) to the fuel pump side of the carb. Then there should be a line leaving the metering side of the carb to the primer bulb then from the primer bulb returning to the tank. When you press the primer bulb you should see it **** the fuel into the carb then from the carb into the primer bulb then back into the tank.
If the fuel lines are all hooked up correctly then you should rebuild the carb.

Fails to stay running / primer bulb does not fill


Double check that the fuel lines are routed properly. Another place to look for a potential problem is where the fuel line comes out of the tank. Make sure the hose is not pinched. The typical fuel line routing is the first line (the one with the fuel filter in the end of it) comes out of the tank and goes to the bottom fitting on the carburator. The second line comes out of the tank and goes to the bottom fitting on the primer bulb and the third line goes from top fitting on primer bulb to top fitting on carburator. Hope this helped and best wishes.

Go to www.searspartsdirect.com and with your model number you should be able to find explode parts views of that trimmer. Filtered line to primer, primer to straight inlet on carb, angled outlet on carb back to tank. That might work. Not sure without part number.

Fuel hose routing problem on a Mac 3200 Chainsaw


This post helped me with my McCulloch Mac 3216 chainsaw. There are two holes in the gas tank - one above the other. One is for the gas line (with the filter on the end) and the other is for the overflow - a simply line that runs from the "out" nipple on the primer bulb into the gas tank. The filtered fuel line goes to the nipple on the back of the carb. Another short line goes from the "in" nipple on the primer bulb to the nipple on the front of the carb.

There are two notches just out from the two holes in the gas tank for holding the lines that go in -- this may help you locate the holes.

I found it helpful to pull the lines that go into the gas tank out through the gas cap hole and leave them hanging out until the housing was reassembled. I also left the lines that plug into the primer bulb hanging out through the hole where the bulb goes until the housing was put back on. Leave plenty of extra line for the lines going out to the primer bulb. Once the housing is in place, cut the lines to the primer bulb and attach them, and slip the lines into the tank, making sure the ends are as far down in the tank as possible. You will need this extra "slack" to work with the housing to get it back on.
