Sim Yamaha put out an instructional video"F225 Service Information VST Removal, Cleaning, Filter/Screen Replacement . I watched it and I was looking at frame 15 where it showed the routing of the fuel lines. How the lines are run is that correct? I am really talking about the cooler lines to the brass nipple on the VST. I tried to down load the picture but our site said it was to big.

I've seen those photos before
(IIRC that 'presentation' was done by a THT member)
but I never noticed that detail -
the hose with the steel 'El' is in a surprising location, right across the VST:
It actually looks pretty reasonable - but that is NOT the way it is routed on my F225TXRD :
nor in the Yamaha Service Manual:
my guess, that was not the first time that owner was removing the VST -
and on a prior occasion,
he re-assembled using a 'novel' placement of that hose

Perhaps not needed, or much, at WOT -
but dropping down and idling after a hard run:
its hot under the cowling and the fuel isn't being consumed very fast,
that HP pump is just cycling it round and round....
