Thanks guys. The fuku couplers are awesome. I've got the couplers, rad hoses and inlet and all are very well made and all fit perfect. The quality is top notch. They are double the thickness of eBay ones and are all really stiff. The inlet should hold high power with no collapsing like eBay ones. They currently sell the green, blue and black and are all snake skin looking. Also they will be dropping white and purple soon as well. Highly recommend them.
