Sending Unit for DET MAR Fuel Gage

ABullard · #1 (**permalink**) 01-21-2003

The fuel sending unit on my sailboat has gone bad. I have DET MAR instruments (1981) but unfortunately the company is out of business.

Does anyone know if DET MAR requires 90 or 240 ohms sending units?

Thanks.

Tony:
Fuel Senders are usually:
(US)240 Ohm Empty, 103 Mid, & 33.5 Full
or
(Euro'') 10 Ohm Empty, 95 Mid, & 180 Full
Try a 10 - 30 Ohm resistor ( Radio Shack?) - if it reads LOW it''s Euro; or if HIGH it''s US.
Connect resistor accross Instrument Ground and "S" or "2"(or sometimes "G") terminal which should have Pink Sender Wire.
Good Luck
Gord

According to "VDO" the Detmar Fuel Sender (Level Switch) is 240 - 33 Ohm,
VDO Part #226 007, which includes installation kit #226 451 (2 1/8" flange, gasket, & misc. mtg. hardware).

consider replacing the sending unit with a wema sensor. They are inexpensive, easy to install and incredibly durable...www.wemausa.com
