Hi all,
Had to remove the carb on the above outboard as the fuel had been sitting in it for quite a while, and needed to be cleaned. When I disconnected the fuel pump, I noticed it was leaking, so I have ordered a new pump.
I could not remove the grey vacuum line as it was deteriorated and so cut of a small section at the end, and now I've noticed this little brass jet? in the end of the line. Of course now I don't have enough hose between it and the end to put back onto the fuel pump.
Can someone tell me if all vacuum lines have this device, and if so what it is? I'm thinking some sort of fuel metering device but ?
What do I have to do to replace this 'Thing"?
Any help appreciated.

All vacuum lines do not have such a device. Appears to be a restrictor of sorts to help dampen the pressure changes within the hose.

What year 2.5 motor? Do you not see the part in the applicable parts catalog?

Just push it a bit further into the hose ....or cut the hose to get it out and then stuff it into a new bit of hose if the old hose is starting to deteriorate ....bit of grease on it so it slides in easy ....Bobs yer auntie 😁

Thanks Mc Tool....just wasn't sure if it was pressed in or not....the original hose is okay so I'm glad I just have to push it further in....appreciate the help.
