Fuel flow meter/gauge kits?

[civicwithawankel]

I would like to find a way of measuring the flow of fuel to the injectors to make a fuel gauge based on fuel consumed instead of the float sender my car came with. Can anyone recommend a good flow meter that can handle high psi fuel lines?

I'm looking for the measuring piece thet goes into the line, and a basic digital gauge readout that can show real time fuel consumption (L/Gal per hour), total fuel used and remaining, MPG overall and 'trip' over a certain distance.

I just want the parts so I can put it together myself for relatively cheap, preferably as a complete kit. Any help is much appreciated
