fass lift pump loud

hey all,

bought a used fass lift pump that has the dual filters on it. i mounted it on my frame and wired it up and away i started it up, didnt take the old filters off or anything. anyway it is very noisy. i changed both filters and it quieted down for maybe 30 mins and now is back to the same loudness. sounds like air in the filter or something. when i crack the w/s drain the noise goes away for 10 mins again. any thoughts?

Pretty sure they are normally loud. I don't have one but everyone I've heard in person is a bit loud

I was going to say, I just saw the video before I saw the post. It sounds like it is sucking air (kinked fuel line would do). Glad you got it under control!

What' do you mean draw line? The metal tubing coming out of the tank before the quick connect is bent? Or is the rubber hose to the FASS kinked?
