New grey fuel line

[Gizmoray]

Can anyone tell me why the newer fuel line/hose collapses at any connection? 2 boats won’t run for more than a couple minutes after hitting throttle. I’ve pulled a couple lines and found at the connections, the inner clear liner was completely collapsed. Using 3/8 inch line. The grey stuff from marine shops. Have 4 different connection on my boat. All are plugged.. inner liner collapsed.

Picture a butthole!!!

Its ethanol fuel that's doing it. Replace all lines, filters and use line that states SAE J1527 type B1

I prefer to go to Napa and buy real fuel line.
