How do you remove gas tank from craftsman lawn tractor 917.20390 ?

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.

How to replace a fuel pump on a1997 Chev Venture

  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.

  1. Disconnect the quick-connect fitting at the fuel filter, and return line fitting.
  2. Disconnect the fuel tank electrical connector.
  3. Disconnect the vapor hose at the fuel tank.
  4. Disconnect the vent hose at the fuel tank.

With the aid of an assistant, support the fuel tank, remove the left and right tank retaining strap attaching bolts, and remove the tank.
  1. As necessary, remove the fuel sending unit (which includes the fuel pump), as outlined, in this section.
  2. Then you can change the pump:
  3. Remove the fuel sender assembly.
  4. Disassemble the fuel pump strainer and the fuel pump: Note the position of the strainer in relation to the pump.
  5. See Figure 3

    Fig. 3: Remove the fuel tank locking ring with a non-sparking (brass) punch.

    1. Support the fuel pump in one hand, and grab the strainer in the other hand.
      1. Rotate strainer in one direction and pull off pump. Discard strainer.

      1. Remove deflector.
    1. Disconnect the fuel pump electrical connector.
    2. Loosen the two connecting clamps, if equipped.
    3. Place the fuel sender assembly upside down on the work bench.
      1. Pull the fuel pump downward to remove it from the mounting bracket, then tilt the pump outward and remove it from the connecting hose or the fuel pulse dampener.
    4. It is recommended to replace the hose and clamps, if equipped.
    To install:
    1. Push the fuel pump assembly into the attaching hose. Attach the pump electrical wires and fasten the hose clamps to the attaching hose and around the pump body, where equipped.
    2. Place the fuel tank sender and pump assembly into the fuel tank. Use a new O-ring seal during assembly.
    3. Then put the tank back in:
      1. If the fuel tank is replaced, transfer the fuel feed and return lines from the mounting clips, the vapor hose from the mounting clips and the vent hose from the vent hose fitting.
      2. Check the fuel filler neck for cracks and holes and replace as necessary.
      3. Install the fuel sending unit.
      4. With the aid of an assistant, position and support the fuel tank and install the left and right tank retaining strap attaching bolts and tighten to 18 ft. lbs.

Which fuel line "port/inlet" on the Walbro wt-380 goes to the fuel tank? It's on a Craftsman 25cc Gas "Weed Wacker" Line Trimmer purchased in 2002. It has Walbro WT-380 carburetor with external primer...

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

Replace gas lines cant get fileter inside tank and gas line throug to engine

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.

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

Primer pump rotten need replacement show parts page

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.
