See my latest “what did you do” thread for background yesterday. I am having the fuel fill cutoff problem. Lines are clear, purge solenoid and vent solenoid working properly. Brand new charcoal canister. This morning, I went back under to check the vent nipple repair on the back of the tank that I had done earlier to make sure that it was not closed back off again (like it did my first repair). Of course it’s hard to get to…. When I put a tube on the nipple and try to blow into the tank, I can’t get any (or very little) into the tank. Since air is supposed. to vent OUT of the tank back to the canister, you’d think that you could blow INTO the tank. When I blow in the tube, it pressurizes and then comes right back out with gas vapors. So maybe some air is coming out, but not enough to vent while filling the tank.
Using various tools, I know that I’m clear back to where the nipple turns down, and using a dental pick with a hook on the end, I can ddrop the end into the downturn part, but not very far. I don’t think anything from my repair would have resulted in a restriction lower in that elbow.
Does anyone know for sure if you should be able to blow into the tank, or is there maybe a one-way check valve made into the nipple assembly to prevent anything from getting in? Seems like the tank should not be venting to the canister all the time??
