Are there any reasonably priced fuel flow meters out there?
I've found them for boats (pricey) and airplanes (priceyier). (both carb & efi)
The basic unit reads GPH, and then there are hookups to a GPS for MPG.
I would think there would be a cheaper unit available for cars (instead of units for those rich boat and plane owners
) with the high price of gas nowdays, that has a basic GPH or with a hookup to a GPS or something like a bicycle speedo for MPG.
