Thanks Frank, The information is much appreciated. Now I gotta decide if I can make this work some how or need to get a new one.

Should be 70-75 ohms at empty. The stated range is 9-73 ohms, but these are "5%" gauges. They can be +/- 5% of the low/high value, so 8-10 ohms at full (or hot on the temp gauge) or 69-77 ohms at empty (or cold). There should be a 60-70 ohm difference, so you've got a broken coil if only reading around half that much. The sending unit must be replaced. The rebuilt replacements can be a bit pricey. You can make a universal sending unit fit by striping the original off and leaving just the mounting plate, then removing the universal unit from its mount and securing it to the original plate. > > I use a http://www.jcwhitney.com/adjustable-fuel-level-float/p2005714.jcwx?skuId=162409&filterid=j1 for this. The cheaper ones are 33-240 ohms and of course won't work. > > ------------------ > Date: Tue, 22 Mar 2011 13:49:57 -0600 > From: "Armand Eshleman"<aje1@xxxxxxxxxxxxxxx> > > Going through the fuel sending unit for the white Javelin. > > The resistance range when the float is moved is 45 ohms with the > float at full droop to 10 ohms at full float.
