Yes, i do, i rev`d the motor several times, if i had to guess it didnt loose too much, though i still have the spring return on the fuel bowl and a regulator attached to my return line.
It didnt sound like running out of fuel, just a little louder than normal, probably similar to the stock sound. I have the pressure set where it just humms with no clacking so there was a definate change.
But, im glad you asked, i now know both pumps work, and if the AD dies i can drive home, whic i had wondered about previously.
