Posted: Fri Jun 26, 2009 3:53 pm Post subject: Fuel Tank Sending Unit & Aftermarket gauges |
|
|
Hi
I'm going to put in a custom dash with custom gauges, partly because most of mine are shot and they need to be replaced anyway.
So, as far as the fuel gauge is concerned,
can anyone tell me how many OHMS the sending unit is in a stock Beetle fuel tank ?
The choices I have from the gauge company are :
0-30 ohm sender
0-90 ohm sender
16-158 ohm sender
240-33 ohm sender
75-10 ohm sender.
I'm usually confused but this time I am totally lost. Any help you can give me would be greatly appreciated.
Thank you,
Dave |

To make that last post a little clearer,
They have a specific gauge for each of those sending units.
You figure out which sending unit you have and then buy the proper gauge.
I don't know how to figure out which sending unit I have. |

Thanks Andy, that's a great start for me.
I don't know what a VOM is? |

VOM - that's a somewhat old-school term for Volt Ohm Meter, back when cheap analog test meters usually only did voltage and resistance. Mulitmeter is usually the term used these days, as digital meters usually come equipped to test for more than just volts and resistance. |

I'm a little confused: if you were using your existing gauge with a new sending unit, then, yes, you would want to match up the sending unit close to stock. However, if you are replacing both, these would just need to match these up, so empty is "empty", and full is "full" - so supplier needs to make sure you get compatible set; it would then be irrelevant what your original sender was. _________________ 1970 VW (owned since 1972) and 1971 VW Convertible (owned since 1976), second owner of each. The '71 now has the 1835 engine, swapped from the '70. Second owner of each. 1988 Mazda B2200 truck, 1998 Frontier, 2014 Yukon, 2004 Frontier King Cab. All manual transmission except for the Yukon. http://www.thesamba.com/vw/forum/album_page.php?pic_id=335294 http://www.thesamba.com/vw/forum/album_page.php?pic_id=335297 |
