EFI fuel supply opinions
 
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.

What do you mean installed the MSD pumps in the tank? What float and pickup did you use at the tank neck?

Which in tank pump? I looked up the 87 pump and pickup and I didn't think it had enough pressure

Had to remove about 3/4 inch off of sending unit tube for outlet fitting to fit, and removed inlet fitting for sock,filter, then plumbed it to selector valve for dual tank operation and need to change selector switch to an 87 switch to provide power to pumps
