Eliminate the quick disconnect on fuel line?
 

I had the detachable fuel line new from the boat builder. First thing
the mechanic did was replace it with a sturdy one piece. A 'quick
release' is just another place for something to go wrong out there...
so if you don't NEED it get rid of it!

If you ever need to disconect and the line is damaged, cutting a half
inch off the line should fix it!
