Ryan - if your bus is wired like mine there is a big ground cable
running with the +12v system and a ground buss tie point (white
wires) in each 12v breaker center. The pump's old ground wire runs
to one of these ground busses. You also have the old +12v wire
running from the pump to the same breaker center. If the old ground
wire and the old +12 wire were tied together at the pump and at the
ground buss, you would have your new higher-capacity ground wire.
Just be sure to find some white tape and wrap a few inches of the
paired wires at each end so future travellers will understand what
you've done.

Be sure to put a fuse at the battery to protect the new +12v home
run. 20a fuse for #12 wire, 30a for #10, 40a for #8.
