Looking for some options for an Direct Injected 6.2L fuel pump? To make a long story short I have a 15 Silverado with a striker crank, cam with higher lift HP fuel pump lobe, Z06/LT4 HP Pump, fuel rail lines to the injectors, and Injectors, OEM fuel pump, aux. external secondary pump activated off of a Hobbs switch when the switch sees 2-3 PSI of boost from the TVS2300. Flex fuel sensor for the E85 tune and alky methanol injection. Wondering if any one has replaced the factory stock in tank pump with another pump and how the fuel pump control module reacts or if just needs to be deleted in the ECM. Thanks for any help or ideas.

My pump and module went out recently.I was told by a local shop that does mainly Procharger high hp builds (1-1.5 k whp) that an external pump is all that is available.
