The BD Diesel Fuel Rail Plug (1050070) is a performance upgrade designed specifically for 2003-2007 Dodge Ram trucks equipped with the 5.9L Cummins engine. This plug replaces the factory pressure relief valve in the fuel rail, effectively preventing fuel pressure drops under high-load conditions. By eliminating pressure bleed-off, it helps maintain consistent fuel pressure, which is essential for improved throttle response, increased horsepower, and overall fuel system efficiency—especially in high-performance or tuned applications. The BD Diesel Fuel Rail Plug is a popular choice among diesel enthusiasts looking to enhance their engine’s reliability and performance in demanding driving conditions.
