Can't remember if its collored or not. Don't pay that much attension to the color. It takes a straight screw driver. if that helps. I couldn't find a picture but i'll look again.

No Puit with the screw closed untill the primer pump it tight. Then open the bleeder.

ok where is the bleeder?
Expert:  Dan replied 8 years ago.

The bleeder screw is on the top of the filter housing by the silver thing that you pump.

 

If you ran it out of fuel, you could have some contaminated fuel. Here is the steps to remove water from the system. You may want to replace the filter also.

Water-in-Fuel Draining

  1. Attach a small piece of hose to the drain cock onto the water-in-fuel sensor.
  2. Place an approved fuel-resistant container under the fuel filter.
  3. Open the drain cock three or four turns or until the water contaminated fuel seeps from the drain cock.

  4. Operate the priming pump until only diesel fuel is visible. Allow the pump to return upwards between pushes.
  5. Tighten the drain cock.
  6. Remove the container and hose.

how long do i crank it for? and do i pump the gas peddle?
Expert:  Dan replied 8 years ago.

After you pump it up and bleed it till all air is out. You crank it over. Then prime it and bleed it again. Then crank it some more. Pumping the pedal wont help much, try holding the pedal 1/4 way down.
