Injectors are male, harness is female.

USCARR to Bosch fuel injector adaptors

1 lb/hr gasoline = 10.5 cc/min (@720 kg/m³) (1 (pound / hr)) / (720 (kg / (m^3)))
$Flow_{new}={\sqrt {\frac {P_{new}}{P_{old}}}}Flow_{old}$
Density of typical test fluid = 760 - 770 kg/m³
1 lb/hr = 9.81 - 9.95 cc/min
Density of n-heptane = 685 kg/m³
1 lb/hr = 11.0 cc/min
3 bar = 43.5 psi
4 bar = 58.0 psi
5 bar = 72.5 psi
