Hello,

Picture obviously not mine, but I've marked with red marker 2 tubes (by the g12 container), curious what they for. It rattles like crazy.

Been googling and unsure. My advice would be to cable tie them to make them secure if possible. Or ask your local mechanic what the hoses are.

They're tied together, but the problem is, that the connection itself where those tubes come from is not very solid, maybe something vacuum related or loose, but it doesn't look like it's screwable it's more push kind of thing.

Could tgey be for the heater/heater matrix? I say this as I remember my wife having an issue with her old fiesta a long time ago and the pipes were in a similar configuration. Of they run into the bulkhead then I would hedge my bet that that's what they are.

Those 2 tubes connect here, I'm not so sure about that.
