Michael's idea is to fabricate a simple 1.5 inch square piece of flat aluminum plate mounted to the original bracket's threaded hole, which moves the original pump mount upward, allowing it to be rotated enough that the straight tubes are not a factor (pink arrow). The original pump mounting bracket and rubber insulator is retained. Simple.
The relay is bypassed by jumping the two colored wires (not the green) found in the relay's wiring connector, allowing the pump to run whenever the key is "on." This is easily reversible, if desired.
