Even though General Motors trimmed down the standard equipment for its 2003 Buick Regal model, the 3.8L engine remained the same. The powerful V6 engine requires an unobstructed fuel filter to keep the amount of fuel flowing as needed from the fuel tank. Before your Regal’s engine begins to fuel-starve and lose power, replace the old filter at home. You can perform this task in a Saturday morning using a few tools you might already own.
Tools Used: Tools, Wrench, Ratchet, Socket set, Shop rags, Small flat-head screwdriver, Floor jack, 2 jack stands, 2 chocks, Open-end wrench, Flare wrench, Ratchet extension, New engine oil
