Would fuel economy go bad from having the two small hoses break of the passengers side of the plenum chamber?(my fuel econ has gone bad) They control the fuel pressure solenoids. What diameter would replacement hose be? 3mm?
Thanks.

yes take what you have of what is left of the pipe

its the vaccume line off the fuel pressure regulator

very important -and does effect fuel ecconomy

It was really killing the fuel economy, especially on small stop start trips. I though it was just the symptoms of an old worn engine (271K km) using more fuel to to the same work until I found both those small hoses snapped off.
