Never heard of a fuel filter vent line. The fuel filter has a return line which routes fuel back into the tank. The canister should have 4 ports, tank vent, carb vent, manifold vac and purge signal.

Here is a simple page about it.

Okay, I just thought it was interesting that my return line is 5/16/ and that is only a 1/4 outlet

 

That would be a carb float bowl vent if your carb has such going to the charcoal canister. The gas filter return line coming off the 'top' of the gas filter runs back to the tank sender unit. be sure it is up top.

 

Thanks Mike, here is a new development. Gas came pouring out of one of the lines that I believed to go to the outside cto fitting, any ideas? I can't seem to find a diagram that really helps explain carb lines, regardless of all the searching, googling, and external links I can find.

Any thoughts on the gas issue?

Ps I only test fired it by pouring gas in the carb, could I have just poured too much in?

Thanks!

 

These may help. Not my pictures, copied them when someone else posted them a while back.

 

Thanks!

Yea I have seen those...they have been very helpful in figuring out 90% of my issues!

My problem i think is I don't know the carb side.

 

Guitar....Can you post a picture of your carb and let us know what line the gas came out of? Maybe a drawing of the lines the way you have them now...

 

Too much gas can pour out the front corner port maybe when you poured it in if you have a BBD.

 

That is where the gas was coming from. That goes to one of the ports on the CTO, correct?

Sorry to sound like a newbie, but admittedly I am!

I'm on my iPhone right now, but I will post a picture when I get back to my computer.

 

That can feed the CTO on some, on most I have seen it is capped.
