Any issues with using the dual-tank setup with a high-pressure late model EFI system? My 87 has a stock tbi 454, and sometimes dirty thoughts of a 6.0 keep creeping in. I've seen my share of guys putting TPI on their trucks, but never noticed if any of those used dual tanks. I understand that I'd have to upgrade the fuel pumps, fuel lines, etc, but wasn't sure if (or how) I could retain the dual tank switch-over business. Can that equipment handle 55+lbs of fuel pressure? If not, what are my options for retaining dual tanks?
