all screw-type hose clamps need a snugging up a while after being newly
installed.
And then periodically....once a year at least. Not 'mash things' ..just
nicely tight but not too much. The hose wants a little more clamp
pressure after a while.
Can't have no fuel pressure regulator banging and swinging around , or
able to, in any decent installation or configuration.
It does matter.
Flex, the frequencies and dynamics of those flexings, and vibration,
etc............. all need to be managed and looked after on all wire
and hose systems, on all vehicles..if ya want it safe and reliable.
Have you seen a positive battery cable rub against an oil filer for
5,000 miles ? ..and what that can do ?
( it can happen on a stock diesel vanagon if ONE plastic clip on that
battery cable is not there ( super dumb VW ! ..a fire waiting to happen ).
Yep ...[psitive battery cable rubbed against ) the conveniently
located oil filter _ , until it zapped through, lighting the hot oil in
the oil filter and thus engine on fire.
That vehicle is where I really learned the value of managing vibration
and rubbing contact situations, especially around and on the engine.
