Hi does has any body know the internal diameter of a caterham Xflow bottom hose. I'm thinking of using one on my xflow locost as it will be tidier than using a collection of elbows and joiners but the hose needs to be 1 1/4" at each end to fit the water pump and Rad. Don't think the water pump end will be an issue but not sure of what Rad Caterham used to fit
Thanks Graham
