I've had a blue pump yeas ago on my old setup,as a matter of fact,i had (2)of them that last for years with no problem until i went with the new bullet then one started to leak so i went to the a-1000 pump but i still run one of the blues on my nos side for fuel and i'v always thought that i should run a safety shutoff in case of pump failure U posted this thread have just confirm that.............
