d both fuel lines into the tank. The bulb still does not fill with gas. I removed the filter, placed my finger over the end of the tube and pumped the bulb; no suction. Where could this be losing suction?

The fuel filter might be clogged. A clogged fuel filter is most commonly caused by leaving old fuel in the leaf blower. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog the fuel filter and cause the engine to stall.
ANSWER: The primer bulb, which is located in the fuel line between the gas tank and the engine, is used to fill the carburetor with fuel when the engine is started cold.
If petrol is coming out of your primer bulb, this means that it is backing up in your carburettor and flowing out of the primer tube. The float-valve in your carburettor has most likely got stuck and just needs to be adjusted.

Need to replace fuel lines….does the prime bulb connected to return fuel line or the supply fuel line
ANSWER : Hi stglass900…

Normally the big line will be the line the fuel filter is connected to inside of the tank, and is connected to the primer bulb.
The smaller of the two lines is the return line to the fuel tank from the carburetor after it is pumped thru the carburetor by the primer bulb.

Have a craftsman 16″ chain saw 358.360260. Could not initially get it started after it had sat for a couple years with fuel stabilizer in it. When I went to use it the fuel had all evaporated and the fuel pick line was rotted. I replaced that with some difficulty but finally got it on. Saw still wouldn’t start. Replaced the fuel filter. Still wouldn’t start. Pulled the carb apart and cleaned and recleaned everything. Diaphragms were good and I didn’t adjust any of the mixture screws because as I said it ran fine before storage. Non of the carb passages were clogged. Fresh gas 40:1, good spark plug and good spark. Airfilter is good. Engine has maybe about 4 hours of total run time on it. It’s a ZAMA (?) carb. It will run for about 30 seconds when I manually prime it by pouring a small amount of fuel directly though the carb. When I was disassembling the carb the vent hose that goes back into the fuel tank seemed to have a small out of ?substance? in it which I cleaned out. It was right at the end the of the hose that goes back into the fuel tank and not up by the carb. It didn’t appear to be like your typical gummy deposits/varnish though. I hope it wasn?t some type of spongy check valve stuff that is supposed to be in there. That might explain some of my problems. Anyway, I also can not seem to get the primer bulb to fill. When I open the fuel tank, look in side and depress the primer bulb, air bubbles come out of the fuel filter. But when I let the bulb reexpand there’s no fuel that gets sucked up the hose. I can however seem to fill the primer bulb when the fuel tank is full and the chainsaw is laying on it?s pull cord side and the bulb is depressed a bunch of times. The saw will also start and run again for about 15 seconds then die. It’s definitely not getting/fuel and probably running out . Thanks.

I have a husqvarna 323L string trimmer. I stored it after running the tank & carb dry for about two years. I fueled it, then started it, & it ran for a minute then died like I turned the switch off. Since it would not restart, I found the fuel filter had broken off the hardened fuel line & it sucked gummy crap out of the tank & into the carb. Failing at cleaning the carb, I finally put a new carb on it & replaced the pump, hoses & filter. It has ran good till this year. I winterized it with stabilizer & left it with a full tank over the winter. The gas in the tank was gone when I got ready to use it this year. I filled the tank with premix, checked for leaks, then started it. It would run fine for about half a tank, start idling poorly (lean) then cutoff & refuse to restart till I refilled the tank. I finally found the tank had cracks & was letting pressure out of the tank & apparently this was causing the carb to lose it’s ability to siphon gas out of the tank. So I replaced the tank which came with new hoses & a filter, which I properly installed to the carb. It cranked right up, but when it runs a half tank, the carb quits sucking gas out of the tank. When I pump to prime the carb, it moves the fuel into the carb, but the pump never gets hard like it does when I prime the carb when the motor is cold. I have to keep refilling the tank, prime, & then it starts & runs until the tank gets about half empty. The new fuel filter is down in the gas tank properly, but It will not run after it shuts off until I refill the tank & prime. I’m baffled. New tank, new hoses, new filter, new carb, & I can find no leaks in the fuel system. It runs strong. The 323L is a two-stroke & it always cranks on the second pull from cold on a full tank. Any ideas?

Which gas line goes to which connecter on the carb? I disassembled to clean and it’s having pressure issues. The tank is filling with pressure and the bulb won’t retain enough gas to keep the
ANSWER : The thing to remember is that the primer pulls fuel from the carb into the bulb and dumps back to the tank, it does not push fuel into the carb, connect the fuel line from the tank to the carb connection nearest to the alluminium pump cover held with a single screw, the other one goes to the shorter of the two connections on the back of the primer.
