Funny little pipe?

Featured Replies

Hi All,

 

I was de-rusting and undercoating my 92 Subaru Loyale, 4WD, wagon, and noticed a bit of rust on the metal pipes near the fuel pump.

 

I found one that is not part of the fule pump but is near it.

It is a metal pipe that goes through the rear floor on the passengers side, about 6" back from the fuel pump.

 

This hose is almost rusted in half and has a 1/4" hole in it.

 

What is this funny little pipe for?

Is this part of the emissions system?

Could this be why the check-engine light came on?

How easy is it to remove and replace?

I doubt it.

 

Unlike OBD-II systems, our older Soobs do not have any way to measure whether the Purge Control Solenoid is plumbed or not, other than the coil impedance, so as long as you have some kind of coil of the correct impendance connected, the ECU doesn't care if the vacuum lines are connected or not, AFAIK.

 

1995-on, it makes a difference, and if you leave your fuel cap loose, it'll tell you.
