Fuel Sending question

[dlowe01]

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??????

One wire should be grounded to the frame and the other goes to the gage. You have to make sure that the sender in your tank matches the gage. My Midstates uses a 69 Camaro tank and I had to use a SW gage with a 30 ohm resistor. I think Stewart warner has an electric fuel gage that uses a 240 ohm resistor.

Bottom line is find out what sender you have and match the gage accordingly. Try calling Cravin Mabrey @ Stewart Warner...he is the sales rep for aftermarket gages...phone # 704-785-8506
