|
|
Just bought a ‘98 CD22 and I want to remove some fuel of questionable age/quality. Tried plastic tubing into the fill port but ran into anti-siphon I think. Removed fuel line from kicker and tried to start a siphon with the primer bulb to no avail.
Any ideas? |

The filler hoses can have a pretty good S bend in it which might make getting a siphon hose into the tank tricky. If the boat has a Racor filter, I'd try siphoning from the inlet hose to the filter. Make sure the fuel shut off valve is open to the tank you want to siphon. |

I use an automotive fuel pump. If you have a Racor filter, it will most likely have two inputs and two outputs. You want to pump the questionable fuel thru the second input--that way you are not running the fuel thru the filter.
The automotive fuel pump, needs a small inline paper type of filter or screen mesh type of filter. You want the pump, the battery powering it (can be the boat's battery) and the container you are putting the fuel into away from the boat. I use an. ignition protected switch.
If you don't have a razor, then take the hose off the motor and attach the suction hose to the automotive inline pump to this.
Legally discard the fuel, or burn it in small engines, mixed with fresh fuel. _________________ Bob Austin

There is a big bend like the others noted. It's also pretty easy to just remove the filler hose at the tank and start siphoning.....been there and done that. |

I did what Bob describes when I got my C-Dory and wanted to remove the old fuel. My filter doesn't have a spare port, so I pulled the filter input line and attached the pump there. _________________ Gerhard |

Good method Bob... I finally got in the water this weekend and realize that I don't know how much fuel is on board... It's pretty close to 1/4 tank with weight in the stern, so I would like to calibrate to know just how much is on board. I could siphon the remainder, or fill up. I don't particularly want all that weight, but I've heard that in our humid climate in winter, it's better to keep a full tank to prevent condensation. What do you guys think? |

Shove a small finish nail along the side the ball check valve in the kicker motor supply hose. Lift the end of the hose above the height of the fuel tank. Gently pump primer bulb until hose is completely full and fuel is seeping out end of hose. Drop hose into a fuel can and a siphon will start. Pump primer bulb a few times to make sure the flow is going well. Have an extra 5 gallon can to swap over when first container is full. Be careful not to leave to prevent overflow. Pour the removed fuel into your pickup (only if from previous boating season). |
