2G Do I need to rewire my fuel pump?

[97gst2]

I just put in some delphi 580's and my new ecu today and im about to put in a walbro 190. I have an evo3 16g and I want to run close to 20psi. Would I need to rewire the 190 to achieve this?

A good rule of thumb, if the wiring is stock... rewire it!

You'd be alright at only 20 Psi, but re-wiring the pump is very easy and worth it.

One would be wise rewiring the stock pump. Based on this, I would rewire the 190lph pump.

Smaller wire=heat. Heat=resistance. Resistance=more heat...... see where that leads? Round n round
You want large wiring going to a high load source like the fuel pump. It can't hurt to do that and really clean all of your ground wiring

especially for $20-25 and alittle of your time!

Do it becouse later on you might want more than 20psi

Like dsmkauai said for 20-25$ and your time it's worth it. You can get everything you need from a local auto parts store, or you can order a kit like STM sells with everything you need including a pigtail for the relay for $30.....defiantly spend the little bit of cash and spend some time and rewire your pump it's all worth it in the end!

I would defiantly rewire the pump and maybe for for a walbro 255lph. That should give you plenty of fuel for a long time.

I'm going to agree with everyone on the rewire. I just installed my walbro 255 with stock wires and at idle you can hear the pump almost choking. Just do it once and forget about. Ebay has a kit for around 20$ that gives you everything.
