A modified fuel reservoir designed for specific Ford vehicles produced between 1979 and 1993 incorporates a specialized depression or “sump” at its base. This alteration enhances fuel delivery, particularly under high-performance conditions, preventing fuel starvation by ensuring a consistent supply to the fuel pump, even during aggressive acceleration, braking, or cornering.
This modification addresses limitations inherent in the factory fuel systems of these vehicles, which often struggle to maintain adequate fuel pressure when subjected to the demands of increased horsepower or competitive driving. The enhanced fuel supply provided by this system contributes to improved engine reliability, consistent performance, and reduced risk of engine damage due to lean fuel conditions. Historically, this modification has been a common upgrade within the performance automotive community seeking to maximize the potential of these popular platforms.
