Senior Airman Sarnia Trego, fuels preventative maintenance

Senior Airman Sarnia Trego, fuels preventative maintenance technician, and Airman First Class Cody Merrick, fuels distribution operator, both assigned to the 60th Logistic Readiness Squadron, perform a maintenance check point inspection on a R-12 Refueler Mobility Unit (R-12), June 10, 2016, Travis AFB, Calif. The R-12 is a mobile jet fuel pumping, metering and filtering truck. Victaulic flexible grooved couplings and aluminum fittings are utilized on this truck for service connections and to allow the plumbing systems to “flex” when the truck is taken off-road. The R- 12 pump systems, hoses, filters and etc., undergo these inspections on a continuing basis to maintain operational readiness, reducing the chance of equipment failure.
