Hello, my name is XXXXX XXXXX I will try to help you with this.
You do not need to drain the tank to replace the fuel pump.
Just to be clear. There are two fuel pumps. A low pressure lift pump in the tank and a high pressure pump at the front of the engine.
Hope this helps.
Please remember to rate my assistance.
Thank you Mark, very Helpful. I already knew this but just wanted to confirm with an expert.
