    That doesn't make any sense. Why is gas leaking out of your charcoal canister. Its meant for filtering vapor. Can you be a little more specific about what you did during the install.

This part is a vent solenoid to the EVAP system. The solenoid is controlled by the PCM & vents fuel vapors to the charcoal canister. If fuel is leaking here you should first make sure your vent in the gas cap is not clogged.This could cause a vacuum in tank & possibly lead to your problem, or the solenoid may have been damaged when the tank was removed & replaced.

Replace fuel pump


Best to do this in a well vented area because of the fire hazard, so that the gas fumes don't accumulate.
1) Disconnect battery negative cable.2) Jack up car and support on safety Jack stands3) Siphon gas out of tank4) Remove three rubber hoses on rear of tank. These are used for gas fill up; remove hose clamps and disconnect.5) Remove three hoses from front of tank; these hoses go from the fuel pump to the engine. You'll need special fuel line wrenches for this.6) Disconnect two connectors at the front of the tank.7) Remove two bolts that hold the exhaust pipe heat shield. You'll want to use penetrating oil on these; they will be corroded.8) Support tank with a floor jack. Remove the bolts which hold the tank in place. Pivot the tank on the exhaust, tilt and slide out.9) The gas hoses are taped to the tank. Remove the hoses. The fuel pump plate has about 12 screws around it. Remove the screws. Lift the plate out. The fuel pump is retained with one screw. Remove the screw. Filter is retained with a clip; remove it.10) Get your new fuel pump ($250), the rubber gasket for the fuel pump plate, and new filter ($5). Compare the pump with the old one; it must be the exact lenght. I had to go to two different auto parts stores before I got the right one.Installation is opposite of above. Good luck!Fuel pump is not too tough. First, get a Haynes or Chilton manual for reference (about $14).Best to do this outdoors, so that the gas fumes don't accumate.

Leaking fuel and refusing to start.


If the leak is above the gas tank, then the piping on the fuel pump is probably corroded. You will need to replace the entire pump assembly.

Check the entire fuel line for corrosion or breaks in the rubber hoses. Is the fuel pumping out on the ground when you are trying to start it?

How do you replace the fuel pump on a 1993 hondalx


If your engine has a carbuerator, then these are the steps:

Externally Mounted Fuel Pump
  1. Disconnect the negative battery cable.
  2. Remove the gas filler cap to relieve any excess pressure in the system.
  3. Loosen the lug nuts of the left rear wheel.
  4. Elevate the rear of the car and support it safely on properly placed stands. Remove the left rear wheel.
  5. Use a pair of suitable fuel line clamps to pinch shut the fuel hoses leading to and from the pump.

  1. Disconnect the positive lead wire and ground wire from the pump.
  2. Remove the fuel pump retaining bolts, taking care not to lose the spacers and bolt collars.
  3. Remove the fuel pump and its protective cover as a unit.
The pump cannot be disassembled and must be replaced if defective.
To install:
  1. Install the fuel pump and cover. Make certain the mounting collars and insulators are in the proper location. Tighten the mounting bolts to 7 ft. lbs. (10 Nm).
  2. Engage the wiring to the fuel pump.
  3. Connect the fuel hoses, making certain the lines are correctly placed and the clamps are secure. When in doubt, use new clamps; they are cheap insurance against leaks. Remove the fuel line clamps.
  4. Install the left rear wheel. Lower the car to the ground.
  5. Install the fuel filler cap. Connect the negative battery cable.
  6. Turn the ignition ON for 3 seconds, listening for the fuel pump operation. Switch the ignition OFF, then ON again. This will build pressure within the fuel lines.
  7. Start the engine. It may crank for several seconds until the lines are completely filled.

Trouble code P0442 on 2001 dodge ram 1500" what steps should i take to diagnose what the problem is?


P0442 means you have a small leak in your EVAP System. your can try replacing the Gas cap since it's the easiest thing to do and reset the check engine light with a scanner. If the check engine light came back on then your going to have to go though all the Vacuum line in the EVAP system and connections. The other thing too is the service engine light should turn off when the problem is addressed and it may take up to three start ups to clear. Good luck and keep me posted, be glad to help, Recap, change the gas cap and inspect all the hose and connection's to the EVAP system.

I JUST GOT A 525I BMW AND THE SPEEDOMETE WON'T READ IT LEAKS FUEL


hello charm city, if your car is a pre 1996 model, I would take a look at the speed sensor mounted on the differential. It will have an electrical plug (2 pin). It is held in with one or two small bolts. What area of the car is the fuel leak at. You have rubber fuel hoses at the front and rear of the engine and at the fuel pump in the trunk. there are also some at the fuel filter under the car near the right rear subframe area. the get brittle and start to leak with age.
