Title: Fuel guage
Post by: rdbishop on January 17, 2011, 09:06:05 AM
Where's the best place to buy a fuel guage? I'm ordering a sending unit from centroid and they need to know what guage it's going to conect to. Help!!!!

Thanks,
Richard

Yes, check out the catalog shown.   Here's what it says about one fuel gauge:

     [Specs for: FUEL LEVEL GAUGE 2]     MARINE GAUGE
     New FARIA. Built for marine use. Gray background with white markings. Goes from full at 33 Ohm sender signal to empty at 250 Ohm sender signal.

See the "full at 33 Ohm sender signal to empty at 250 Ohm sender signal."?   That's the spec.  You need a sender that matches the spec of the gauge that you intend to use.  I've been told that many fuel gauges are either "Ford spec" or "Stewart-Warner" spec so usually it's pretty easy.  Tell centroid the "Ohm Spec" of the gauge you're using and they'll match you up with the right sender.  You can start out with a good sender and match the gauge to that, or, you can start out with the gauge you want to use and match the sender to it.  Either way works -- all that matters is that they match up.

I saw the guage but it has a gray background, and I want a black one of course.

Yeah, that's good, just pick out the gauge you want and tell centroid the Ohm rating.  As I said, most of them are "standardized to not the same standard" but the match is usually pretty easy.

Where I am, it's pretty hard to beat NAPA prices; Stewart-Warner has a big website too but it seems pretty clunky -- both state the Ohm rating for each gauge.  But if somebody is trying to sell you a gauge without the Ohm rating, that's a sign that the seller doesn't know what he's doing IYKWIM.
