Rebuilding a Racor FG500 Fuel-Water Separator
By Capt. Bill Pike
My first step was, of course, shutting off the fuel valves on both my two fuel tanks. Then I put a bucket under the unit and removed the plastic drain assembly (which I discovered was on the verge of failing) from the bottom of the bowl using an adjustable wrench, thereby allowing quite a bit of fuel to whoosh into the bucket. Loosening the assembly meant rotating it counterclockwise, by the way. Backing off the T-handle at the top of the unit and removing the topside lid, as well as the filter element inside the canister, finished the draining process in short order.
