Attaching line from gas tank - Stihl HT101 Pole pruner

First, drain the tank. Then pinch the clips attaching the gas line (you'll need needle-nose pliers) and slip off the gas lines. There will be some gas spillage - it's unavoidable. There will be some bolts holding the tank to the mower chassis. Loosen and remove them. If you have a manual, consult it at this point. If you don't, just think logically and you'll be OK. NOTE: YOU DO NOT WANT TO ATTEMPT THIS IF THE ENGINE IS STILL HOT AS IT COULD BE VERY DANGEROUS.

There is a slightly easier way of getting the lines in which attaching a tag wire to end of the taper tubing and pulling the line thru the tank openings. Most time you don't even need to lube the lines and if you use the regular two fuel mix.

Here is picture of the wire is attached.

1. Properly relieve the fuel system pressure and install a pressure test gauge according to the tool manufacturers instructions.
   
2. Turn the ignition switch to the ON position for 3 seconds, then turn to the OFF position for 5 seconds. Repeat this procedure two or three times to pressurize the system. Again turn the switch to the ON position.
   
   1. On TBI equipped vehicles, the gauge should read a static pressure of between 9 and 13 psi (62-89kPa)
      
   2. On SFI equipped vehicles, the gauge should read a static pressure of between 41 and 47 psi (248-325kPa)
      
   3. If not, check for a clogged fuel filter, a kinked fuel line, or an inoperative fuel pump.
      
3. On TBI equipped vehicles, the fuel pressure will drop after the fuel pump stops running due to a controlled bleed in the fuel system. Use of the fuel pressure gauge will determine if the fuel system pressure is enough for the engine to start and run.
   
4. No fuel spray from the injector indicates a faulty fuel or ignition system or no PCM control of the injector.
   
5. This test will determine if the ignition control module is not generating the reference pulse or if the wiring or PCM are at fault. By touching and removing a test light to B+ on CKT 430 (purple/white wire from the ignition system), a reference pulse should be generated. If the injector test light blinks, the PCM and wiring are OK.
   

If the pump tests bad...
Disconnect the negative battery cable.

1. Relieve the fuel system pressure.
   
2. Block the front wheels and raise and support the rear of the vehicle safely. Make sure the rear is high enough to accommodate the removal of the fuel cell.
   
3. Loosen the fuel filler neck connecting tube clamp at the tank.
   
4. Wrap a shop towel around the fuel filter neck connecting tube and slowly remove the fuel filler neck connecting tube from the fuel tank.
   
5. Position a siphon hose into the fuel tank through the fuel filler opening. Place the other end into an approved container with enough capacity to hold the fuel in the tank. Siphon the fuel.
   
6. Raise the vehicle to gain access to the fuel tank. Make sure the vehicle is safely supported.

Usually the line with the filter on it that comes from the tank goes to carb. inlet first which is most likely close to the bottom side of the carb.nearest to the engine,then the outlet or return line on the carb.goes to the inlet side of the primer and the outlet side of the primer goes back to the tank. The primer draws fuel through the carb to the primer to the tank if its not? then correct the line connections until it does

the gas tank will be needed to be dropped to gain access to the top of the tank to remove the sender with the attaching fuel pump on it. basicly you disconnect all lines first then the tank straps. the tank will be lighter if no fuel is in it too

While accessing the inside of the tank thru the fuel cap hole,try attaching the hose to the filter and place it in the tank, then use a coat hanger bent enough to allow you to push the other end of the hose thru the small opening in the tank. Pierce the end of the hose that you pushing thru the tanks small hole. You'll waste about an inch or two of hose while pushing the coat hanger thru, so make sure you have extra in your overall length of hose you purchased. You did not mention what type of blower, so i'm guessing this trick will work for you. It's not easy to do, but it has always worked for me in the past. Good luck.

Fuel pump is located inside the fuel tank and is attached to the sending unit. Do not smoke or have any open flame in the work area when removing the fuel pump.

REMOVAL OF FUEL PUMP:

1. Disconnect the negative battery cable.
2. Relieve fuel pressure
3. Remove the rear seat cushion.
4. Remove the floor service hole cover .
5. Disconnect the electrical fuel pump wiring at the fuel pump assembly. Check for any fuel leakage while in there.
6. Remove the gas cap, this will prevent any fuel gas spilling out of any high pressure lines.
7. Use a fare nut wrench to disconnect the outlet.
8. Remove the pump bracket attaching screws
9. Disconnect the return house from the pump brackets, then pull ou the pump/bracket assembly.
10. Remove the nut and spring washing, then disconnect the wires from teh pump bracket.
11. Remove the sending unit attaching screws then remove the unit from the bracket.
12. Pull the lower side of the fuel pump from the bracket.
13. Unplug the connector to the fuel pump
14. Disconnect the hose from the pump.
15. Separate the filter from the pump. Use a small screwdriver to remove the attaching clip.
16. Inspect all the lines, houses and fittings for any sign of corrosion, wear and damage to the surfaces. Check the pump outlet hole and the filter for restrictions
17. When reassembling, ALWAYS replace the sealing gasket with a new ones. "Also replace any rubber parts showing any sign of deterioration".

To install:

1. Install the pump filter using a new clip. Install the rubber cushion under the filter
2. Connect the outlet hose to the pump and pump bracket.
3. Engage the connector to the fuel pump. Install the fuel sending unit to the pump bracket. The remainder of the installation is the reverse of the removal.
4. Start the engine and check carefully for any sign of leakage around the tank and lines. Road test the vehicle for proper operation.

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

The hoses run through a hole into the gas tank, they are fitted with a filter inside the tank. Drain the tank, and manipulate the hose end to where you can grab it throught he filler hole, Remove the filter, run new gas lines into the tank and through the filler hole to replace the filter, reattach to the carburator. The primer bulb should have 4 small screws attaching it to the carburator. Remove the screws, place in new primer bulb, and you should be back to trimming asap.
