They are the type that you clamp a radiator hose on to either side.

I'm not sure what diameter they are. Heres a picture. There is one already opened, and that's the one i'll use. The other 4 are enclosed in original packaging.

There's also a tach there if anyone wants it, and a block heater cord.
