Eliminate the low fuel pressure codes in your 2004.5-2010 GM 6.6L Duramax with the Attitude Performance 2001 Fuel Rail Plug. Machined in the USA from 304 stainless steel, the Attitude Performance 2001 replaces your factory fuel pressure relief valve. Once your truck is modified or performance tuning is added, the factory Fuel Pressure Relief Valve (FPRV) cannot handle the added pressures. In many cases, this causes diagnostic trouble codes and also drastically reduces performance.
- Eliminates Low Fuel Pressure Trouble Codes
