Oldsmobile Fuel Pump Block Off Plate

Is your Oldsmobile’s mechanical fuel pump having trouble keeping up with your engine? If you upgrade to an electric fuel pump, you need an Oldsmobile fuel pump block-off plate. Our Oldsmobile block-off plates cover the hole left in your engine block when you remove the pump, keeping oil inside your engine. We manufacture these plates in America to exacting specifications for a leakproof fit. Each plate is made from aircraft-grade billet aluminum and comes with stainless steel fasteners. These parts are designed to withstand high crankcase pressures in racing applications, so they’re more than up to the task of protecting street-car engines.

Looking for a way to dress up your Olds V8? We have custom Oldsmobile Cutlass block-off plates, as well as plates with engraved designs for 324-, 350-, 400-, 403- and 455-cubic-inch engines. That covers nearly every version of the Rocket V8 from the original 88 to the 4-4-2. Of course, if you’re more concerned about function over form, we also have blank Oldsmobile fuel pump cover plates.
