The proposed action is the removal and bypass of diesel fuel oil strainers on diesel generator engines 670-M-42 and 670-M-43. Diesel fuel oil strainer parts are no longer available for these units. Hoses, fittings, and tubing need to be replaced to bypass the diesel oil strainers. The strainer on unit 670-M-43 allows air to enter the fuel system causing a drop in fuel oil pressure and will be the first strainer bypassed. The strainer is no longer necessary because of the low amount of sulfur in today's fuel compared to the 1960's. The strainer for unit 670-M-42 is currently operable and is planned to be removed and bypassed at a future date to support equipment reliability.
