Just my luck. Just joined the forum and my truck (2012 F350 King Ranch) 84K miles, throws a P20BA code. Something about a reductant heater bad. So, what say you learned ones? Just delete it or fix this turkey? Cost to delete is about the same as repair.
Repair is not to bad. About a 2 hour job. Buy a hand pump from Walmart or harbor freight and about 10 feet of hose from Home Depot. Cut leading edge at angle to snake into tank. Pump out into clean 5 gallon tank. Pull fuel tank shield. Disconnect fill hose and then drop tank.
There is a video on YouTube about doing this. Part cost about $275-300.00
Not bad to do by yourself.
