I don't expect that clear lines would be able to safely handle the pressures and temperatures present in the engine compartment. I'd stick with certified components there from a safety and reliability point of view.

I dont see why the coloured lines they use for coolant should be any stronger than clear?
By coloured do you mean opaque or translucent? All the hose products that meet automotive specifications are opaque (that I know of).
Flexible fuel lines, coolant lines and oil lines are composite products using different compounds for the inside and the outside and contain reinforcement layers in between. The inside layer matches the fluid characteristics and the outside layer matches engine compartment contaminants.
I don't know of any product that is clear/translucent that can withstand both environments for any length of time that can be obtained for a reasonable sum of money. The first thing I would check with any clear fluid line sold as an automotive product are the product certifications (look for an SAE, DIN or ISO reference marking on the hose/line).
