Help! No power!
I would encourage you to run a relay for this situation.
I am assuming you have the battery in the front of the car.
Use a heavy gauge wire (#10? Hopefully someone will chime in) and run it from the positive (or very near) post of battery. Run this wire all the way back to pump (this wire will actually go to the new relay).
Then run a wire for a switch. This wire can be a much lighter duty (say 16 or 18 gauge). If you don't want some ugly switch sticking out of your stock dash, now is an opportunity to place it stealth and it becomes an anti theft device. The switch needs power too, so keep this in mind. The switch power doesn't need to come from the battery it just needs to be "on" when the key is turned. You could bogart from the fuse box here.
Once you have these things in place, you are essentially running grounds after that.
It's ben a couple months so i may have this wrong, and since Del is on hiatus, well .......
30 is the heavy to batt
87 to hot pump wire (heavy gauge)
86 to the switch (light gauge)
This way you aren't running the power needed by the pump, through the switch, the switch triggers the relay and the power for the pump runs through that heavy wire.
