3rd fuel line on Subaru motor

Hi

Does anyone know what the 3rd fuel line on the WRX motor is for? Do I tee it or block it?

its not the return line is it

Hi

No it has 3 lines grouped together, I would assume 2 are inlet and return, not sure what the other ones for.

i'm not 100% but it may be the return from the charcoal canister to the tank.

Had to ask the same question Steve when the WRX went in. See here

you need a password to access that forum

PS - my guess is carbon cannister. My V6 had it's mounted near the engine.

Yeah the canister, that line runs to the fuel tank vent.

Baja Wes - September 27th, 2004 at 08:33 PM

yeah. I ran two new 8mm lines for the fuel feed and return. Then used the stock VW small fuel line for the fuel tank vent.

carnt you do with out the cannister or do u need it for redgo... i would block it up

you must keep all pollution controls

Baja Wes - September 28th, 2004 at 08:17 AM

yeah, you have to run whatever emmission gear the motor came with. In my case a carbon cannister and a cat. The carbon cannister is so small anyway. Mine's smaller than a coke can.

would this be the same on other earlier engines? i have 3 similar lines from my engine (ea81). one isnt hooked up and at the moment the engine will only run for about 10sec before it dies of lack of fuel, would the 3rd line to the cannister solve this?
