[QUOTE="HS-MotorsportsDallas, post: 1462187, member: 19010"] This comment shows that you know nothing about how a high pressure/low pressure fuel system works. A high pressure fuel system is fed by a low pressure fuel system. If the low pressure fuel system can't meet the demands of the high pressure fuel system, the rail pressure will consequently suffer because of the lack of fuel to the high pressure pumps. A lack of adequate pressure and volume going to the high pressure pump will starve everything. The whole fuel system depends on the low pressure pump. [/QUOTE]
