ok i was looking at walboro 190lph kits for our cars and i want that pressure/extra fuel but i dont want to have to wire up a harness for it so would this kit work equally well? http://cgi.ebay.com/ebaymotors/NEW-H...spagenameZWD1V also ive read that the stock tbi fuel pressure regulator is big enough to return all the extra fuel with this is that true?
