I am installing a V1 on my fox, and followed the directions perfect, cut the hose where I need to but the hose diameter is too small. Measures 1 1/4", but the coolant pipe is 1 1/2". I bought another hose from the parts store and same thing. The hose is 1 1/2" only at the 90 degree portion at the thermostat and immediately necks down to 1 1/4" for the entire rest of the hose. I tried to shove the pipe inside the hose and it's just real tight. I know someone has been through this before. Any suggestions or help would be appreciated.
