Fueling & Injection - ohms for fuel gauge?

Needing to get an autometer fuel guage but don't know what the ohms are on it...anyone know?

Thanks!

GM should be 0-90ohms.

How are you going to make it work I bought one too and don't know how to hook it up to make it read correctly. Mine is a fuel level guage

GM should be 0-90ohms.

Does this apply to all the plastic LS1 tanks too?

hey back from the dead here but I wanted to get a definate answer if the 0 -90 ohms is true for all ls1 vehicles before I go out and buy my gauge. Thanks guys!

ttt again

I can't remember exactly what the OHMs are for a stock fuel level sending unit, it's something like -243 - +35 ohms. When I did mine Autometer didn't make a gauge compatible with the stock F body intank fuel level sending unit and I don't think they do now either. I had to unplug the stock unit and use a 0-90 OHM Jazz fuel level sending unit and an Autometer 2 1/16" Ultralight fuel level gauge and route new wires for it. Not to bad when your replacing all the stock gauges with aftermarket units.

have any pic or anything part numbers for the Jazz sender etc? Thanks for your input!

If it's a swing arm type I don't think you will have enough room in the tank for it to work becuase it will hit the stock fuel pump.

i actually have an aluminum cell but youre right, ill bet it wont clear the stock pump assy.

99+ LS1's (plastic tanks) are 33 Ohms Empty and 240 Ohms full. Autometer sells a gauge with these Ohms settings but it is backwards. I have heard autometer has a reverse aircore they will install in the gauge for $12 and make it work with 99+.
