Q: How to replace Refueling Control Valve on my 2001 altima on 2001 Nissan Altima

I need to replace the refueling control valve on my 2001 altima as the signal port from the filler neck vapor line is broken.
The car runs fine with no codes, but am not sure if this can cause problems.
This is a 3 port round plastic valve that sits under the car on top of the gas tank in a cavity in the rear of tank.
I need to know how to get to it to replace it, is there an easier way or do I need to drop the tank to replace.
What seems to make the problem better or worse? NA
How long have you had this problem? NA

Hello,
Sorry to say, but you have to drop the tank.
This can cause issues with the EVAP system and debris entering the fuel system.
I would drive it until the fuel gauge says the tank is empty. Funny enough, you should still have a couple of gallons of fuel in the tank, but that should not make removal any more difficult.
Plug every hole as you remove hoses and fittings from the tank. It will keep fumes and liquid gas off of you, your tools, and your lungs.
