My fuel gauge is a accurate to about a half a tank. Needle bounces around like mad if it’s not totally full. Is there a reasonable fix for this, or is this a boating inevitability? Seems like every boat I’ve had is the same but it’s getting annoying not knowing how much fuel I have. ------------- 1993 Sport Nautique PCM 351w, no ProTec |

Tyler, Go with a high end linear https://www.wholesalemarine.com/moeller-reed-switch-fuel-sending-unit-79135.html" rel="nofollow - sender There very nature snubs rapid movement. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

Tyler, Sorry but I don't know the length needed. If you don't get a response, then you'll need to measure your tank. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

I installed a Kus sender last fall - similar to the Moeller unit that Pete posted, but only about $50 on ebay. Read the instructions before you order a sender: If you're installing in a metal tank it should be 1/2-1" shorter than the tank depth, a plastic tank will need more clearance. ------------- 1968 Mustang 16 - 351W powered |

Could you explain what you mean by snubbing rapid movement? I have a reed switch sender in my boat and don't feel that it resists fuel sloshing any better than the factory style sender |

Isaac, From the Moeller description: "Reed switch sending units collect fuel level information more consistently than swingarm senders. They achieve this by taking the measurement from the float - which is still a moving part. However, the fluctuation is much less because the range of motion is much less." Another: Moeller Marine Reed switch fuel level senders dramatically reduce "slosh fluctuations" which are inherent with swingarm units. " Did you use a Moeller brand? ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

No, I'm using a Wema sender. I don't think it's a bad unit by any means, but the gauge definitely twitches between different fuel levels (due to the low resolution of the reeds) when the boat is moving. |

Yeah mine usually sits around 1/2, and twitches between empty and full. Basically useless. ------------- 1993 Sport Nautique PCM 351w, no ProTec |

Isaac, The "twitch" between levels should still give you an idea of how much is in the tank. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

It does, and I would consider it to be a perfectly functional fuel level indication. I just don't feel that they do much to dampen rapid fluctuations. |

Does anyone know the standard/typical shaft length for a 1983 Ski Nautique with a metal tank? It has the original swingarm style sending unit. At key on, gauge pegs full when a jumper is placed between the ground and the sending unit wire, otherwise, it's a random level generator. I can pull the tank and check but I thought I would ask in case someone has the length handy. ------------- '83 SN |

Anyone have any experience with Tanks Inc. floatless senders? https://www.tanksinc.com/index.cfm/page/ptype=product/product_id=346/category_id=184/mode=prod/prd346.htm" rel="nofollow - Tanks Inc. sender I was shopping for a 0 to 30 Ohm sender for my X55 and ran into it. I wonder how well it solves the gauge "twitch" problem? ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |
