I've searched a lot and couldn't come up with an answer so hopefully someone can help me. I'm slowly working on a project NA that will have a sheet metal dash and am currently collecting gauges for it. I'm looking at Autometer's website and found this: http://www.autometer.com/cat_gaugede...id=3093&sid=11 Its range is 73 OHM's empty to 8-12 OHM's full. Going by the information on this site which is probably very helpful to a lot of people, the 89 GTU's (not GTUs) fuel gauge's range is 75.9 OHM's empty and 7.4 OHM's full http://www.tamparacing.com/forums/ma...formation.html Are there going to be accuracy issues due to the range difference? That's the closest one I could find, the other one's ranges are completely different.

Has anyone put an aftermarket fuel level gauge in their FC and am I looking at the right one? As always, any help is appreciated. Thanks in advance.

 

Most fuel gauges are rubbish, more a suggestion than a real indicator of fuel level.
The combo you're looking at will probably be about 90% as accurate as the stock setup...which should be entirely serviceable.
