Your carb has two hose connections, one is the inlet and the other is the return. The inlet (suction side) won't have any barbs on it (smooth brass pipe). The return side will have barbs to keep the hose from popping off if the line is plugged and is probably plastic. The inlet side should connect to the fuel filter that will be dangling from the hose inside the tank. Make sure the filter is free to move around the inside bottom of the tank

    You can determine which hose goes where by purchasing short lengths 18" of each tube size.

    1. Attach the tubes to the carb connections.

    2. Place a small quantity of clean gasoline into a clean empty water bottle and place one of the hose ends into the fuel.

    3. In a second empty cup place the other hose end.

    4. Squeeze the primer bulb. If gas flows from the full bottle to the empty one then you have found the inlet or filter side (it's in the gas)

    5. If it blows bubbles, switch the tubes and try again.

    6. If gas doesn't flow you have a problem with the primer and/or carb.

Fuel line problem at fuel filter conector, 1994 Buick Century


I know the feeling well when this happens. I to did the same as you and also did the clamp, but found the best way was to yous a crimp tool for fuel lines and its not come off since its like the tool to put brake lines on to the calipers and then you put the rubber hose onto it and using a fuel line clip to hold the rubber in place. has lasted the last 5 years now with no problems.

Open fuel tank, pour out fuel on clean flat area (away from any flames or spark sources) then check the 2 plastic hoses inside. One should have a fuel filter on it's end. The plastic these lines are made seams to disintegrate so, filter may not be attached and lines may be broken off. Replace them.

The fuel hose from the tank with the filter on the end goes to the main fuel inlet on the carb, this is the conection closest to the alloy pump cover held with a single screw, the other conection on the carb has a hose to the short conection on the back of the primer ( the suction side ) the longer conection on the primer ( pressure side ) has a hose back to the tank, this pipe just pushes into the top of the tank, just remember the primer pulls fuel from the carb, into the bulb, and back to the tank, not the other way round.

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.

The hose coming from the fuel tank with the filter on the end goes to the fuel inlet on the carb, this is the conection closest to the alloy pump cover held with a single screw, now take a hose from the other conection on the carb to the shorter ( suction side ) conection on the back of the primer, take a hose from the longer conection ( pressure side ) on the primer back to tank, this just pushes into the tank, just remember that the primer pulls fuel from the carb and dumps it back to tank.

I need info on a Poulan Pro 445 fuel line routing


I'm so confused. This is reported as a Poulan and McCulloch pole saw, which one? Is it a pole saw? That is the only 445 Poulan I can find. It is reported as an electric but has a fuel routing problem.

If it is a Poulan Pro gas pole saw it is here: PP445 Gas Pole Pruner
The fuel system routing is terrible, but it is all there is.
Fuel Routing follows:
Tank to carburetor (hose in tank with filter on free end)
Carburetor to primer (primer draws fuel from the tank through the carb)
Primer to fuel tank (returns any excess fuel to tank when pushed) HTH

Fuel filter at foer escape 2001 4w chenging


start the engine  open the hood and remove the system fuse 
the engine will stall, the pressure is now relieved 
the fuel filter is in front of the fuel tank, driver side 
wear gloves/saftey glasses and have a fire extinguisher available (who knows!) the filter will have 2 hoses attached at either end. white/yellowish clips attach these hoses. feel for the top of the clip and push the 2 ends in and down. you may have to use a screw driver to pry the bottom of the clip as well. pull the bottom of the clip down, it will not come out of the coupling completely. repeat for both lines, pull lines firmly off of filter. unscrew filter from hose clamp. approx 6-10 oz of fuel will spill from lines and filter. you should use a pan. install new filter, in same direction as last. insert new clips into coupling, discard old. clip on "out" side may be reused if an R clip. tighten clamp on filter, attach hoses. push in clips to lock. inspect for leaks, wipe entire area clean of fuel. insert fuse and attempt to start. Cycle the ignition to run and off three times before starting to pressurize the fuel line. Good luck and hope this helps.

Fuel filter in gas tank is attach to hose and connect to ?


The longest, and sometimes smaller in diameter of the two fuel lines, goes from the carburetor to the bottom of the tank. Leave enough slack in this line so that the filter that attaches to the end will rest comfortably at the bottom of the tank.

The other fuel line goes from the primer bulb to just inside the tank, (about an 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 lines through the 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.

If you need further assistance, just let me know.

Poulan 2150 w/ walbro wt324 carb fuel line reassembly


the fule line that comes from the filter/ pick up will go straight to the nipple usualy the one closest to the middle of the carby.
the other hose comes from the carby to the in or **** side( punp it you can feel it)of the primer and then goes to the tank that is the return/ prime, nothing is conected to it in the tank. if you have the carby one the wrong way around it will not prime. just swap them over..
