Looking to replace my new Autozone rear tank on my F350 crew dually 7.3 diesel. I spoke to the distributor and they claim there is no coating on the inside of there tanks that would flake off and plug my filters. Its a waste of time as I know what I see in my filters. A plastic tank would be ideal as I only want to replace either the side or the rear tank. Looking for the best price as I could only find transfer tank for mucho bucks. Thank you.
