walbro 255 install Should i rewire the pump

I'm about to install my walbro fuel pump but i been hearing that the stock wireingis too small and causes loss of fuel pressure. should i rewire the pump with bigger wires and a relay?

I didn't rewire anything, but I guess my turbo setup (Greddy) doesn't need the highest of pressures.

yes you should rewire the pump.. your pump will run down to 10 volts if not rewired.. im right at 600whp on 1 unmodified walbro with a standard rewire
