Can I hook 12 v directly to my fuel pump to check it? I Was wondering if it went through a transformer maybe to drop the voltage, or is it just straight 12v. Stan

It's a straight 12V
"It"s a straight 12V"
GOTTA be careful with a "one-size-fits-all reply like that!
He didn"t state WHAT Ford it was... newer ones have returnless fuel systems and the voltage/power to the pump is modulated by an electronic box called a "fuel pump driver".
PROBABLY OK to give the fuel pump full 12 Volts for a SHORT time, but be aware that things are getting MORE complicated all the time.
HOPEFULLY someone with more experience on those systems than I will chime in!

Bob's answer is important. DC does not work in a transformer. Pulsed DC will, and AC will, but DC will not induce output in the windings. Most are 12v. Jim
