May the force be with you Dusty! We just had our first, 5 weeks ago. Been learning a lot....

I run the 5/16" fuel line, and have noticed the rubber becoming pretty stiff (I've had mine on for over a year), I dont expect a rupture persay, but I do really like the looks of the silicone hose posted on this thread. I may be up grading on my next coolant drain. I do carry spare line and water in the rig.

 

Congratulations Dusty!
