Harmon Racing Cells 18" 0-90 Ohm Tube Type Fuel Level Sending Unit Coated For E85 Ethanol Fuels

Harmon's coated 5 bolt fuel level sending unit's have a protective coating on the circuit board to prevent any damage from E-85 Ethanol gasoline.

Made by ISSPRO, these sending units are restricted to diesel, gasoline, or E-85 Ethanol with the unit connected to a single fuel gauge that utilizes a 12 VDC negative ground system voltage. No adjustments can be made to the length or resistances. Standard hookup is two 10-32 studs.

Note: 5 bolt fuel gauge sending units are intentionally asymmetrical. Meaning the spacing between each of the 5 bolt holes isn’t even. Keep spinning the sending unit around and eventually the holes will line up with your fuel cell.

• 0 Ohm = Empty
• 90 Ohm = Full
• Terminal Marked G = Ground
• Terminal Marked S = Fuel Gauge

Note: 1998 was right at the transition when GM changed from a 0-90 Ohm sender to a 40-250 Ohm sender.
