    I've wondering this question for a while now and no one on the other auto forums really knows the answer. Hopefully one of you engineers/students could answer it.

    As one goes for higher horsepower, say 600whp+, they usually upgrade the fuel pump, hard fuel lines,injectors and fuel rail.
    My question is solely about the hard fuel lines. My fuel lines are 5/16" and I have a fuel pump that will flow 200lph@ 72psi (and 6x 760cc/min injectors).
    Ignoring the various couplings and the fuel filter how much can the 5/16th fuel line and gasoline with a density of 0.67 flow in volume/min?

    Why don't you set up a test and and measure it yourself? You will be more satisfied with the results than you would be with an analytical calculation. EE here.

    I would go for the test idea...
    I am thinking a fuel tank and pump on one side and a pilot flame on the output side:D
