Dual A1000s sumped

Does this look about right for a dual sump configuration? Run them staged and have the one pump turn on with hobbs switch only when needed. Also use a 16306 so that the single pump doesn't get hot when rolling around town. I'm wondering if Hellmann or XDP some other company makes a fuel sump with dual 10 AN bulkheads. I suppose one could just tap the other side of the sump 180 deg from the feed port.

Not good for over 1200 rwhp on E85, but a much cheaper solution is 3 of the 255's in tank. Or duel 450's in tank. Just have to deal with possible fuel starvation in the non baffled 99-02 plastic tank and that hobbs switch malfunctioning. Then again if you have holley efi, there's other safety provisions that help in case a pump fails. Wiring an indicator light up by the fuel gauge so that if a pump fails the light comes on is another option.

Dual 450 walbros and 2000cc injectors is roughly 85% duty cycle at 1150rw on E85.
Dual 465's are probably good for 1300rw on the corn and are the same size.

Then there's the hell cat 525's which are the same size as the 450's
