The longest, and sometimes smaller in diameter of the two Fuel Lines, goes from the bottom of the carburetor, to the bottom of the tank. (The first line will need to be longer so that you can pull it all the way through to where you put gas in.) This so that you can easily attach the fuel filter. Then pull the Fuel Line back through the hole. Leave enough slack in this line so that the filter that attaches to the end will rest comfortably at the bottom of the tank. Cut off any excess line once you know that you have enough to reach the carburetor.

The other Fuel Line goes from the primer bulb to just inside the tank,(about a 1/2 inch). (Make sure that you get the right size fuel lines.) The plastic coupling goes on the end of this line, inside the tank. This keeps the line from pulling out of the tank.

(HINT): When feeding the Fuel Lines through the fuel tank holes, cut the lines at an angle. They will feed much easier into the holes. You can than cut them off square, once you know that you have enough to work with.

Three Fuel Line Installation: In this installation, the primer bulb is separate from the Carburetor.

The (1st) Fuel Line will be the longest, and sometimes smaller in diameter of the (3) Fuel Lines. It goes from the bottom of the carburetor, to the bottom of the tank. (The first line will need to be longer so that you can pull it all the way through to where you put gas in.) This so that you can easily attach the fuel filter. Then pull the Fuel Line back through the hole. Leave enough slack in this line so that the filter that attaches to the end will rest comfortably at the bottom of the tank. Cut off any excess line once you know that you have enough to reach the carburetor.

The (2nd) Fuel Line goes from the top stem of the primer bulb to just inside the tank,(about a 1/2 inch). (Make sure that you get the right size fuel lines.) The plastic coupling goes on the end of this line, inside the tank. This keeps the line from pulling out of the tank. This will be the shortest of the three Fuel Lines.

The (3rd) Fuel Line goes from the bottom stem of the primer bulb to the top of carburetor

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.

Poulan chain saw model #2025 - fuel lines dry rotted and disintegrated. There are 3 fuel lines: l from gas tank and 2 from primer button but only 2 fuel ports on the carb. What goes where and how?


You should have 2 to the tank, the one with filter coming from tank goes to nipple on right side of carb, the nipple on left side by primer bulb goes to primer bulb and other from primer bulb back to tank as return line, how it should work is when you push primer bulb it pulls fuel from tank through carb and back to tank on return line so watch in tank orleave one line out that you think is return line and see if gas comes out when you prime, but remember it goes through the carb first before it goes back to tank, had a pic but too big to put on site sorry, 2StrokeJim

Hello, my Ryobi 410r tiller/cultivator needed new fuel line so I bought the fuel line, return and a new bulb primer. Unfortunately, I can't remember what hose goes where!!! Specifically, I've...


The primer pulls fuel through the carbruetor
So take your return line from the carb. and hook it to the inlet side of the primer and the other side
of the primer bulb transtions into the fuel tank.
You know when you have hooked it up right when you press the primer it fills with fuel and dumps back into the tank.

Are you sure you have conected the pipes the correct way round, the fuel hose from the tank with the filter on the end goes to the main fuel inlet on the carb, nearest to the alloy pump cover, the other conection off the carb goes to the shorter conection on the back of the primer, the longer pipe on the primer goes back to the tank, just remember the primer pulls fuel from the carb, into the bulb, and back to the tank.

Walbro WT891 carb on a Craftsman chainsaw. Carb is brand new, all fuel lines and fule filter replaced. I prime the carb with the little plunger, chainsaw starts up and runs out of fuel within 30 seconds....


Who connected these hoses? the normal routing for a machine with a primer is like this, the fuel hose from the tank with the filter on the end goes to the carb fuel inlet nozzel ( not to the primer ) nearest to the pump cover ( cover on carb held with one screw ) the pipe from the metering side of the carb connects to the shorter nozzel on the primer bulb ( suction side ), the longer nozzel on the primer ( pressure side ) connects to the pipe going back to the tank, just remember the primer pulls fuel from the carb,into the bulb, and pushes it back into the tank, it is not actually a primer it is a purge. because it is connected this way it is impossible to flood the engine no matter how many times the bulb is pressed.
Let me know if it starts and runs.

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.

Chain saw, there is a line from primer to the carb, then what? I cant tell if coming out of the carb it goes back to primer or in the fuel tank? Then should there be a line from fuel tank to the primer?


Similar to this, typical fuel system.

  • 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 bulb, an output line from the carburetor connects to the suction side of the primer (once the bulb is collapsed it draws fuel from the tank through the carburetor to refill as it inflates).
  • The pressure side of the primer returns displaced fuel to the tank as it is depressed.
Take lots of notes and a few digital photographs to help with reassembly. HTH

Fuel line routing on ryobi 775r


One line ( the one with the fuel filter in the end of it) comes out of the fuel tank and goes to the lower port on the carburator. The second line goes from the fuel tank to the bottom fitting on the primer bulb. The third section goes from the top port on the primer bulb to the top port on the carburator. Hope this helps and best wishes.

Gasline mixup


one line comes directly from the fuel tank (the one with the filter) to the inlet side of the of the carbruetor ( the bottom fitting on the carb.usually)
the other line coming out of the fuel tank is the return fuel line and it hooks up to the outlet side of the two fittings on the primer bulb
the other side of the primer bulb goes to the only fitting left to hook to at the carbruetor.

you have 2 different length fittings on the primer bulb itself
the longer fitting is your return line hook it up to your tank side and the short one goes to carb.fitting
when you get it hooked up press the bulb several times and see if it primes as it should(fuel moving thru lines) from tank thru carb. thru primer back to tank
