Hi,
I think it is www.racetronix.com. As I remember,it is a pretty straightforward installation, and their kit is very complete. Are you doing the pump too? It doesn't affect the hotwire installation, as the original sender harness is retained, but a Walbro 340 will add spice to your fuel system, never have to mess with it again, unless you get north of 500hp. Good luck!
Hi,
It's been a couple of years since I installed my kit. I thought I had got the instructions online, but maybe not.I can poke around the shop come Tuesday, my next work day, and see what I have regarding this, or you can call Racetronix on Monday, and I am sure they will fax you proper instructions. Let me know if I can be of assistance. Please email me, as I am not on the board daily. Good luck!
