My 86 GL has begun puking fuel out of the charcoal canister.  Mechanic suggests unhooking the vent line from the throttle body and plugging the hose to which it connects to see if anything changes.  Raw fuel now pukes from the vent line.  I have located and exposed the vapor separator to see what it looks like, but do not want to just start yanking stuff apart until I have qualified guidance. 

Local supplier -  SUBARUPARTS.COM - TACOMA SUBARU - offers new vapor separator, but I don't know if that is my problem.  

Engine is 1995 2.2 fuel injected.  Installed by professional.  It ran fine for a few months but recently developed the aforementioned problem.

Thanks in advance.

G’day grandpa Phil! 

That sucks mate! To paint a clearer picture, you have an ‘86 L series with the EJ22 fitted? 

Any recent maintenance that’s had anything to do with fuel lines? Usually the cause of fuel coming out of the charcoal canister is fuel lines incorrectly connected. 

There could be another issue at play where the fuel tank is pressurising and pushing fuel out the vent line. 

Hoping you can provide more info on this to help resolve the issue. 

Cheers
