What's in the Box

Info

Fuel level gauges are designed to work with specific sending units that vary from one automobile or gauge manufacturer to another. Some increase resistance from Empty to Full, while others decrease as the level goes up. For a builder updating their vehicle with new gauges, this presents a problem in that the aftermarket gauges must match the sending unit located in the tank. This module will allow you to use your stock sender with any fuel gauge. You no longer have to remove the tank to add a separate sending unit or modify the sending unit that comes with a aftermarket gauge set.

  • Simply wires in-line between your gauge and existing sender
  • Allows you to use your stock sender with any fuel gauge
  • No need to remove the tank to add a separate sending unit
 
Learn more about selecting the proper fuel sending unit by reading our tech article, Fuel Sending Units

Great product for fine tuning your fuel gauge

October 15, 2015
I have used six of these modules so far and they are great for fine tuning your fuel gauge. I especially like that it gets rid of the wild swings of the needle every time I turn a corner. Plus the low fuel level light is a neat feature. Overall I highly recommend it.
Pros:
  • Simple to Install
  • Easy To Customize
  • Versatille
Cons:
  • Adjustment Knob Is Tiny
Yes, I recommend this product.

E36 BMW sending unit compatibility Hi, i am wondering if your module would work with the sending units in my E36 bmw. Those have 2 sending units in the tank(left an d right) for 500 ohm full and 20 ohm empty. Is your module compatible with this range of resistance?? If so i would be very interested. Thanks a lot!

We apologize but this interface module only goes up to 240 ohm full and will not be applicable to your needs.

will this module correct the real time needle movement on my new classic instrument fuel gauge? the gauge is 0-90.the sending unit and tank are new and are a direct replacement for original. also 0-90.The tech support for Classic instrument said this would help. Since the module cost as much as the new gauge I want to make sure before purchase.

It's hard to get an idea of what your issue is by your description of "real time needle movement." If the tech support at Classic Instruments said an interface module would help you issues when you described it to them then I would have no reason to doubt them. To get any fuel level gauge to read accurately you have to use an interface module like this unit. They are a great addition even to a gauge that is working properly since you can adjust the full and empty readings to be correct.

This will work with nearly any fuel level gauge. Your gauge will have a specific resistance range that it requires from a fuel level sender. As long as your gauge operates with one of the resistance ranges that this Interface Module will transmit then it will work with your gauge whether its a standard gauge or digital.

Why 6 wires?... my sending unit only has 2 wires (which go directly to the gage), and the gage then has 1 additional wire (going to 12v power)? Am trying to Make-do for a 1987 F350 pickup, having 2 tanks and unknown type of sending units (20-80 ohm resistance). Currently the gages read Backwards and (when the sending units are grounded) the gages only go 1/2 up the scale (eg read Half Full). I suspect that the sending units were replaced by previous owner with GM units.

6 wires ? red 12volts black Ground Green to fuel gauge yellow to sending unit white low fuel light as long as both of you sending units are the same (ford is 73-10) you can install the module between the gauge and fuel tank selector switch on your dash. If you do not know what your senders are fill up tanks and remove wires from senders. Take an ohm reading between ground and sender. if you get close to the readings below it is a gm sender. 90ohms 0-90 30ohms 0-30 If you can not do this the module has the capability to custom set the empty and full points If you ground the sending unit wire the gauge should got to full or empty depending on the gauge if it does not you have gauge, wire of selector switch problem. Start from th back and keep grounding the sender wire until it pegs the gauge. if it never pegs it is most likley the gauge.

The gauge interface module works for multiple applications of which detailed instructions come with. Red is 12 volt switched power, yellow is to the sender, green is to the gauge and “S” terminal, white is to low fuel light, black is to chassis ground, and gray is a dip switch wire of which has been preset. Only black dip switches are set to match the sender and the gauge and instructions will list how they are set.

I have a ATL fuel cell with their sending unit mounted in the cell(240/33 ohms). The cell is mounted in a 1961 Ford Galaxie Starliner and I want to use the stock dash and fuel gauge which I believe is a lot lower ohms. Will this unit work with this application?

This interface module can be set for the aftermarket 33-240 ohms and then the gauge can be set to match the sender unit arm in the tank.

I used your module on a custom install. The module worked flawlessly for 2 months and today while driving the gas gauge started flashing just as it did before we used the module to convert an calibrate the gauge. The sending unit ohms out fine and there is power to the unit. There is no change when the sending unit is unplugged from the module leading me to believe the module failed. Since there are no real trouble shooting guidelines in the instructions and it worked fine for 2 months any input would or suggestions would help. Should the red LED be on when the key is turned on? The unit was installed in a clean dry project box in the vehicle as recommended and there is no damage to it.

It is our understanding that the red LED should be on when the unit has power. First check the power source and of course ground. To trouble shoot you can call Scott at 386-212-1611. If found to be defective simply contact customer service for a replacement if purchase was made within the last year.
