Any one out there using electric stewart warrner gauges??? The units came with sending units but I am using a stock mustang tank and the stock unit because the S.W. won't fitt. The problem I am having is that the stock unit has 2 terminals on it and the fuel guage is a one wire. When I hook the wire up to one of the terminals the guage registers full, hook it up to the other and it registers about 3/4 of a tank when it only has about 2 gallons in it. Should the other terminal on the sending unit be hooked up to a ground??? Any one using a similiar set up out there with any suggestions??????
