You need to use a relay. Running a hot wire all the way from front to back for the fuel pump is not good, amperage draw goes up. Using a relay lets you run just a small wire all the way back. The small wire only throws the internal switch in the relay, so it doesn't have to be large. Get one for about $5 at a parts store. I use the kind like they seel for use with off-road driving lights. 30amp, heavy duty.

Wire it like this:
10ga wire from battery terminal (or better yet the emergency cutoff switch for the battery) to the + terminal on the relay.

Small 16-18 ga wire from the ignition switch wire (or seperate switch) to the switch terminal on the relay.

Orange wire from the blue pump to the load terminal on the relay (good idea to use an inline fuse holder in between here)

Ground terminal on the relay grounded to the same place as the black wire from the pump.

I use crimp on connectors, but also solder them in place and then cover the joint with heat shrink tubing.

Later,

Mine is wired just like Dave's and it works perfect!
