Is there something I can install in my fuel line that accurately measures fuel?

Does anyone know what the device that new cars use to measure how much fuel is used at a given moment?

I want to measure the efiiciency in an older engine that I'm using for an experiment on fuel efficiency. What i need is a way to measure how much fuel passes through the fuel line - like a counter of some sort. Any ideas?

why not measure the fuel beforehand?
measure in a cup and see how long the engine runs.

what you are looking for in your quote is called a flowmeter and there are various types.

awesome thank you. i will search flowmeter. I want to be able to do experiments under varying conditions, like on the highway at a constant speed. i considered redirecting the fuel source to come from a tank that is inside the cab which would provide more precise measurements then the fuel guage.

Efficiency can be measured by:
1. filling a litre bottle with fuel outlet at bottom.
2. Connecting the bottle to the fuel inlet hose.

These aren't too expensive
