In my RV7 with AFP fuel pump the fuel line runs along the center floor section to the fuel cube which is mounted on the firewall. Even though I have a smooth WW prop the floor has a fair amount of vibration(more of a buzz). I have the line laying on a thin foam pad for chafe protection but my question is whether there is any concern for fatigue cracking of the aluminum line. Any thoughts or recomendations would be appreciated
 
is the line

secured? Or just laying on the foam? Needs to secured with at least 1, and most probably 2 adel clamps. The vibration wil go away.

Tom, Thanks for your reply and follow up phone call. I will get you a picture of my set up. I believe most everyone with the AFP pump in an RV7 has a similar set up since it is standard Vans design. My only difference is that I have the fuel cube mounted at the lower edge of the firewall.
 
vibration solved...

by using A/C 3/8 ID foam tube around fuel line in floor under center panel, inexpensive and easy to install. my .02:)
