Attitude Performance Fuel Rail Plug

The Attitude Performance Products 2004 LB7 Fuel Rail Plug for your 2001-2004 GM 6.6L Duramax is designed to replace the stock pressure relief valve. This valve helps maintain fuel rail pressure during heavy engine load conditions, while eliminating the potential for low fuel rail pressure DTC Code P1093. Unlike other Fuel Rail Plugs which are made of mild steel and plated with zinc, the Attitude Performance Products Fuel Rail Plug features a 304 stainless steel construction. Made in the USA on a state-of-the-art 7-axis CNC lathe that ensures the best quality, fit and finish.
