1G Fuel Pump Rewire for Aeromotive 340

[er82]

I installed the Aeromotive 340 stealth pump and have rewired with 10 gauge wire from the relay to the fuel pump hangar assembly connector. The wires for the pump itself are not 10 gauge. The question is, do I need rewire all the way to the hangar?

You need to rewire all the way from the battery back.

Most people do not mess with the wires in the hanger from what I have seen. I left the stock ones when I rewired my 450lph and I still saw the benefits.

If you decide to and most people don't, use a proper electrical pass through designed for gasoline.

I rewired my walbro 450 up to an inch away from the pump. Probably doesn't matter but I've heard people make the argument that it's the length of that tiny wire that matters. I just got it as close as possible leaving myself a bit of wire in case I ever had to redo it.

It's pretty simple to run 10 gauge to the pump if you really needed to. Run an isolated bulkhead stud. Can even make your own for under $2.

Your good.

fuel pump wire size on a 2g is 1.25 mm(2), it should be about the same on a 1g. Id say 5" or less from the relay to the fuel pump connector, should be okay.

And use wire with the correct rating.

• GPT wire (SAE J1128-GPT) - General Purpose Wire rated -40F to 176F (Generic wire found in most auto parts stores)
• GXL (SAE J1128-GXL) - Thin insulation, Automotive Cross-link Wire rated -49F to 257F
• TXL (SAE J1128-TXL) - Extra thin insulation, Automotive Cross-link Wire rated -49F to 257F

GXL, and TXL wires are oil, gas, acid and generally chemical proof.

Thanks for everyone's input. I will leave it as is and see what happens.

Can you explain more please

Buy a cheap nylon nut and bolt from homedepot and drill and tap the center for a thinner steel bolt. The nylon nut/bolt is your bulkhead- isolator and the steel bolt is your pass through bulk head stud.

Cost next to nothing and readily available.
