yamaha 115 4 stroke need help

[esko01]

Hello, I have a question regarding pressure relief valve. I took it off, and didn't pay attention how it was installed. There is an arrow on the valve, but i am not sure in which direction I am suppose to put it back. Any input is greatly appreciated.

place it in the same direction as the muffler bearings.
in other words, your post makes no sense.
either word it from your service manual or post a picture.

hello Rodbolt
really appreciate your reply...Problem is that I am new to the boating and really not joking here.There is an air hose from HP fuel pamp to the air intake silencer. On that hose is air presure valve installed. On that air presure valve is an arrow sign.The question is should the arrow sign be turned towards hp pump or towards air intake silencer. I don't have owners manual, so it makes it even more difficult. Thanks

from the HP pump there is only ONE hose, no valves, it simply goes from the HP pump to the rail.
thats why your post is confuzzeled.
me, I can picture in my mind ALL the circuits, vent,pressure and electrical.
your post is simply to confusing.
best I can tell from your confused post is your talkining about the VST air vent valve.
doesnt do much and is most likly not your issue, not that you posted one.
