fuel flow sensor?

[droptail]

I want to make a mpg display for an older vehicle with carburation. Any sources for getting a fuel flow sensor?

Thanks,
James

Hi James,
there are some finished fuel meter available (some are made for boat engines).
Sensors for gas are not found easily, check McMillan www.mcmflow.com , they have what you need but not inexpensive. Does your old car have a gas return line (carburator to tank)?

Thanks for the reply. McMillan is USD$200, a little pricey for what I was looking for. No return lines for gravity feed older fuel systems.

Once apon a time (late 80's?) certain models of Ford cars with carburetors had an external fuel flow sensor in line with carburetor. The sensor was used for a onboard gas mileage calculator...

I had a GF years ago who had a Ford Capri (I think it was a Capri) with the 2.6L V6 and it had the mileage calculator and fuel flow sensor.

Maybe you could still score one at the auto parts store or wrecking yard.

Good lead, didn't know that. I will pursue.

At least Conrad.de sell fuel meters at reasonable price.

Here is one example of fuel meter circuit: Fuel Meter by Possi
Used fuel meter: Fuel meter (DURCHFLUSS-IMPULSGEBER INDUKTIV POM) (in German)

I hope this will help you. I have my own plans to make fuel meter too. Still under planning stage...
