Fuelab sharpened their pencils when it came to machining and managed to squeeze roughly 30% of the weight out of their popular 515 series regulator, while also increasing the flow and giving the regulator a fresh, new look!

The monster 565 series of regulators have been around for some time, but they never really had a place. Fuelab didn’t have a pump that required its massive flow capabilities, but they do now! The 565 Series has now been given a fresh look and will be part of the new PRO Series line of parts that Fuelab is offering.
