EFI fuel supply opinions - The 1947 - Present Chevrolet & GMC Truck Message Board Network

My long bed 77 has the stock dual tanks that work and feed well with the carb setup. I just purchased the MSD Atomic EFI to be CARB compliant here in California. I have their fuel pump kit that goes with it. I also currently have the Pollack 42-308p six port dual tank transfer kit to swap if I go that route rated for EFI PRESSURE. I'm worried about fuel starvation and weighing other options. Ideally, what would you do? The truck currently has 16 gallon tanks so I'm considering a swap to 87 20 gallon tanks. As well as a FITech or Edelbrock fuel sump kit if I keep the stock plumbing.
