Quote: So essentially a larger diameter tubing reduces the fuel velocity and the pressure losses.
In firefighting Pump operations this is referred to as friction loss. The larger the hose diameter the less friction loss given the same hose length and discharge pressure.
Good discussion
My old 446 was using a 3/8 line with a Carter HV 120gph mechanical. The car ran 116mph @ 4100 raceweight...do the math.
The new 572 will be using 8an lines with a Mallory 250 and return style regulator. This motor made 705hp on Dwayne's dyno.
