What's the proper method of running a fuel line? My fuel filter it right
behind the engine, attached to the port side stringer. The existing fuel line is partially braided fuel line, then a coupling to a fat black hose, then a fitting to copper tubing. I'm sort of guessing this was a patch job through the years, as I don't know what purpose this would serve. Is it acceptable to simply run a braided fuel line from the filter to the carb? It would be 3 - 4' in length. Or is some of the old tubing rigid to keep the fuel line away from high temp areas (manifold)? |

I'm no expert but did research a little for out fuel line run...so take this as you will: The small rubber hose in-line with the copper is to stop any stray electrical current traveling in either direction. More likely from the engine to the gas tank. To prevent sparks. ~~ People told me not to use copper line. I don't remember the reason. The previous line on our boat (a 1957 Chris Craft) was a copper line and we DID replace it with new copper line. But I made sure it was very well secured and also the the nylon "clips" holding it prevent it from rubbing against anything and so it doesn't vibrate. ~~ I also used a section of rubber hose a little before the carb. ~~ In our case I also ran a GROUND WIRE from the gas tank to a ground point. This is because the filler neck on our tank is a metal nipple pipe that is scresed directly into the tank. There can be (I'm told) a static charge (or difference in charge) between/on the tank and/or and gas-nozzel. Hope that helps. Good luck. Gary I also |

Approved hose can be used up to the fuel pump. Metal line must be used between
the pump and carb. "Douglas St. Clair" wrote: What's the proper method of running a fuel line? My fuel filter it right behind the engine, attached to the port side stringer.
