Yes they sure do. I feed mine from the tank to 10an Filter to the pump with 10an.
I go 8an from there to the regulator and 8an return. I learned of this pump on theturboforums.com. Guys use them with great success. Big boookuu power too.
It is a continuous duty pump and it lifts fuel up to 5 feet and self primes as well. Cant beat it for the $$..!
