fuel pump rewire question

[boostjunkie92]

so im doing a fuel pump rewire on my colt. I ran some 10 gauge wire off my battery (in trunk) up to the front to power 3 gauges. the wire just happens to run next to the fuel pump sending unit harness. My question is can I just tap into that 10 gauge wire for the 12v to the relay or should I use another dedicated 10 gauge wire from the battery? I have the wire fused with a 7.5a fuse i believe.

i would run a new one for the fuel pump. you should be good with a 20A fuse, the painless wiring kit uses a 30A

Are you saying trigger the relay with the original fuel pump wire? Thats what you're supposed to do.

He wants to tap into an existing 10ga wire that happens to be in the vicinity. I would run new 10ga wire with a 30a fuse to the battery. It'll be easier for you since the battery is closer. I made my own rewire kit for under $20 utilizing home depot and eBay.

Run your own dedicated 10g wire to the relay for your fuel pump. U want the relay to have its own dedicated source to only handle the fuel pump.
