Fuel consumption sensor

Assuming it worked to begin with(why did you buy used?), do this:

Because used costs only ~GBP 7.50.

But I only wanted to knew if I can use this fuel consumption gauge. Originally my BMW did not have it, and I can easily pull RPM/Fuel Consumption gauge out, and put my RPM only gauge.

Reading more this NG archives it looks to me that this is only for fuel injected models (and, as I wrote, I have carburetor). But no harm in asking.

No, I will exchange RPM gauges.

I see. You want to modify it. It's not fun. Here is an example:

Thank you for your time, but id did not help. My instrument cluster (E30) does not look at all like the one in E34. Second link is for adding more gauges (E34 again). I wanted to knew if there was a sensor for fuel consumption gauge, so I can add one. Unfortunately, there is no sensor, fuel consumption is calculated from amount of fuel injected, and speed of the car. I have carburetor, so I can not use this gauge.

If it's not physically possible with a carburetor then ... Anyhow, I'm sorry I can't help. I wish I could since you're a linux guy and all. Till next time. Peace bro.

I'm not sure if BMW fitted this gauge to carb cars, but one the way fuel use is measured on others with carbs is by a small turbine fitted in the fuel line.

I knew that, that's why I asked how does it work. But after some research on the Internet i found that it can not work on carb BMW-s.

Worked just fine on my '88 E30 316 (1.8 M10 carb).

Really? All the info I found seems to point that this gauge shows how much fuel is INJECTED in correlation with speed. Any idea where sensor is? On a fuel line? Vacuum?

I spent couple of hours trying to find how this fuel economy gauge works, where is the sensor, and it seems that opinions are that either it is for fuel injected BMW's only, or it may be that it is vacuum sensor but no one has seen it.

I would really appreciate some help here, it seems that this gauge also affects oil and inspection service intervals (one opinion in this NG), and as mine is shut at max fuel consumption I will not get accurate reading's.

I checked my Bentley, Haynes and some German E30 manual, no sign of sensor for fuel economy gauge.

Anyone with '88 316 1.8 M10 carb engine that can verify/help?
