Jaz Products 378-090-03 Tube Type Fuel Level Sending Unit 8" Long 0-90 Ohm

Jaz 5 bolt fuel level sending units are restricted to diesel or gasoline 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.
