Spring clamps are what OEMs use on low pressure lines like PCV and coolant, because the spring band automatically expands and contracts as hose temperature fluctuates, so the clamp keeps tension through heat cycling without ever being retorqued.\u003c\/p\u003e\n\u003cp\u003eOn sizing, EFI clamps are specified by clamping range in millimetres, so measure the hose over the barb rather than on its own.
