I just got my walbro 392 255LPH inline pump in today and need to know what gauge wire I need for the main power wire. Also what relay do I need for this thing too? I have the mounting brackets and fittings but nothing else. Any advice to make this install easier? As for now I'm just gonna look off of the vortech T-rex install instructions I found on www.superchargersonline.com. Thanks for any help.
