Eventually, I realized that the problem with the DFR was the aftermarket solenoid-style fuel pumps. Because they didn't allow fuel to bleed back into the tanks (like the original impeller-style pumps), the DFR was unable to switch, and it would jam midway, blocking all fuel flow.
So I replaced the DFR with these valves from NAPA, and a SFR. There have been no fuel problems since.
The solenoids are carefully plumbed so that, when UNpowered, they default to the same tank. Wiring them is simple: they're parallel to the OTHER tank's pump, meaning, when the pump for the other tank runs, the valves are energized & direct fuel to & from the other tank.
Even though this section is strictly for low-pressure fuel, I still chose to use EFI-rated fuel hose.
