What is this hose? (Possible fuel leak)

[jus10inbrla]

Been smelling gas something fierce last few times ive ran to get chicken feed. at one point, the fuel line to the sensor (forget what its cLled; just beside the throttlebdy) was sending too much fuel / had come unplugged. Well now it seems like same issue.


found a barb hose broken off on the front.. but idk what its for. at one time idk why but i think it was a vent?

anyway. Let me know what yal think.

I think that one goes to the EVAP canister.

This is the module I’m referring to the hose had come unplugged from the firdt time.

Yep! Thas the name of it!

so i guess 2 new barbs and some tubing.. on the evap i guess i will see where it routes back to ?

iirc 2 fuel lines connect on the evap rite? I definitely still saw one connected

There are NO "fuel lines" on the vapor canister.

There are fuel VAPOR hoses, no liquid fuel.

It’s a hose from your TBI -> charcoal EVAP canister -> fuel tank.

I used NiCopp to run my line from the tank to the EVAP.

If you look at the top of the canister, the ports are labeled. TANK, AIR CLEANER (not connected, capped), and PURGE. The purge line goes to that port on your TBI immediately next to the large port for the PCV. The tank line goes to to the vent port on the fuel sender. This is the arrangement 1988-1993. For 1994-1995 the purge line has a purge solenoid introduced between the TBI and canister.
