Spring in bottem heater hose

Ok, I gather, if you have an old thin soft hose from back in the day you need a spring. If you have a new improved thicker hose you don't need one anymore.

NAPA didn't have any with a spring anyway.

I guess I will run it as is and If I have any problems with overheating at the end of the 1/4 or on the Hwy on the way there, I will investigate further.

Thanks for the input.
