The factory SRT6 and SLK32 fuel filter/regulator has been holding us back due to the inconsistant fuel delivery, this is the solution.  Paired with the walbro 255lph fuel pump and high flow fuel filter this is the basis of our fuel system.  This package includes an AEM adjustable fuel pressure regulator (good to 1000hp), a TOVIC 0-100psi mechanical fuel pressure gauge, the needed inlet, outlet and return fittings along with the appropriate high presure fuel line and clamps.  The fuel filter and pump pictures below are not included. 

This is not to be used with the factory fuel filter/regulator.
