Since I had to remove my Paxton to do the oil pump gears on 2011 GT, I thought I would replace my butchered upper rad hose and my lower hose (rubs against my AFR connector) with flexible silicone hoses that aren't pieced together and can be routed better around the SC. I tried measuring both the existing hoses and the rad connections. The best I could come up with is an I.D. of 38mm or 1 1/2" for both the upper and lower hoses. Anyone know if this is the correct size? I thought I read somewhere that the lower rad hose was usually a larger diameter.
