Or put a nice sized capacitor across the power feeds right in front of the pump. The capacitor will allow alternating current to pass through it, and back to the source, without going to the pump motor. It will also buffer and smooth out the DC voltage going to the pump itself. If you buy the MSD capacitor, you get a nice mounting bracket with it.
Now, it's nothing magic, just a 26 Kufd capacitor (that you can buy from Mouser for a lot less). Installing it just takes stripping back two wires and screwing in a clamp.

I do that with my MSD box, even though it's wired a foot from the battery. There are tons of threads on how the capacitor extends the life of the MSD box.
