Anyone else out there also having a problem with a noisy FASS. I have a new FASS and FASS replaced the pump, but that did not work on getting rid of the noise. It is on my 05 250. The pump is an f13 90 g. It is putting out 65 lbs on my guage, but Fass says my guage could be off. Truck runs ok, but the pump chirps like a bird is in it. I also replaced the filters and dropped the tank. Everything was clean as new. I am looking to upgrade the diptube to half or threequarter, but will not pay Fass $40.00 for the few fittings FASS sells. I can get them here for less, for sure. Besides they do not have three-quarter, just half inch. I like to over engineer everything I do.
