Need diagram on how to route gas lines from carb to gas tank


As a rule you will need to put the smaller line in the smaller hole in the tank and the larger one in the larger hole. Cut the line on a 45 degree angle to get it started through the hole and then from the inside of the tank pull the line through. Be sure to put the fuel filter back on the line to the carb. in the tank.

Need to replace both fuel lines on My BVM200 LE leaf blower, 1 large and 1 small fuel line, can You tell what size they are??


On your blower, it looks like the small line supplies fuel to the carburator which will be connected to the fuel filter in the tank, and the large line looks like the fuel return line.

Diagram fuel lines tank primer carbutor poulan pro weedeater


I have no diagram but here are the instructions on how it goes.
The small diameter line out of fuel tank (has filter in-tank on end) connects directly 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. This is the return line. 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 sometimes the line is held in place with a nylon nipple connector that keeps the line from pulling out of the tank. Otherwise, the line should enter the tank for about 1/2" or so.

Have a poulan pro ppb350 31ccweed eater runs short time. put a carb kit in carb engine runs a short time.then dies.not sure if fuel lines are in correct place on carb?


This is an ongoing issue for users, and rightfully so. 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. Years ago on 2-stroke trimmers, primers were not even used,...you choked the carb with a slide lever and gravity let fuel enter the carb from above...a few pulls, a "pop"...slide it off of choke and away you went.
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 fuel tank.

Not shore wat side of carb hose gets filter large hose or small hose? The larger hose goes too the pump side and the small hose goes to the other side?


Small gas line goes thru fuel tank and has the in-tank fuel filter on it and connects to the outlet on the BODY of the carburetor. The other larger line goes from the Purge?Primer bulb on top of the carburetor to the larger hole in the fuel tank and is only a fuel return line. The fuel filter holds the small line in the tank and a small nylon connector holds the larger line in the tank or it can just be pushed thru 1/2-3/4" or so and it will stay in place.

Trying to replace the fuel line and the primer hose both were rotted off not sure what goes where on my poulan pro ppb200 31cc string trimmer there are two lines into the tank the primer wont fill i have...


The smaller line is connected to the fuel filter in the tank and goes on the carb body opposite the end with the hole in the cover. A larger diameter line coming out of the tank is the fuel return line and has the little connector on it just inside the tank to hold it in place there
It goes on the carb body (if primer is on carb) by the bulb.
If there is an external bulb...the small line is the same...there would be a larger line going from the carb body (nearest the end with a hole in the cover) to the smaller nipple on the primer bulb. A third larger diameter line would be connected to the larger nipple on the primer bulb and running to the little nylon connector inside the tank. This is the fuel return line and the smaller diameter line is of course the fuel supply line.

Best Poulan Engine Match (probably real manufacturer):
http://www.ordertree.com/modelinfo/PWE/BC2400-Gas-Trimmer-Type-6/75.BC2400-Gas-Trimmer-Type-6.1.59.1.html

My decisions are being driven by my experience with Poulan chainsaws. Small hose in tank (long enough to reach all corners), filter on bottom, connects to lowest connection on carburetor. Small hose on upper carburetor connection to small fitting on primer. Large hose from large connection on primer through largest tank hole, roughly mid tank long. nothing on bottom. I suggest you leave the 2 connections on the carburetor long enough they can be swapped (just in case) then try it. if no go swap them.

Typical fuel system and a suggestion or two:
http://www.fixya.com/support/r3706813-2_cycle_fuel_system_repair

This is how I would configure it if a chainsaw, doubtful they would do something completely different. In defense of Jerry, he knows how it should be done, clarity of instruction could use some help. Good Luck. HTH

How do I install fuel lines on a poulan chain saw model 1950?From carburator to primer,from primer to fuel tank,two connections on each.


The smaller line comes from the fuel filter in the tank to the nipple on the side of the carb with the cover w/ 1large screw in the center, the other small line goes from the other nipple on the carb to the primer bulb, the larger line goes from the other nipple on the primer bulb back to the tank, and only gets pushed in about 1/2-3/4" into the tank. Hope this helps.
