The vacuum need to be retained for at least 10 seconds just after closing the motor. The fuel pump found linked in the above mentioned a few assessments must be used in the fuel method.
As an example, the fuel pump fuse Here's rated for twenty amps, as well as the circuit flows about ten amps with the DVOM established to capture min/max readings and also the throttle snapped broad open.
