Does using a biocide require near-term replacement of fuel filters? - Page 2 - PeachParts Mercedes-Benz Forum

If there is no water present in the tank you should not get any new growth. Then the only way to get bacteria is from an infected supply tank. It happens occasionally.

If I had bacteria and used a good biocide on it I would consider it done unless I got reinfected.

I have driven some of my diesels a decade or more without infection.

No way to completely avoid condensation happening in the tank....but keeping it ' fuller' on average as compared to ' emptier' would reduce it...

Install a pressure gauge between the lift pump and secondaryfilter so you can monitor the condition of the filter and change it before it clogs to a no start condition.

Use Startron and go about your business, without the Filter worry.

This is the most direct and correct answer, and the only one to address the difference between a bio agent and an additive like Startron. Biobor, biokleen etc kill the little nasties but do not dissolve them in the fuel, so you can expect to have to replace fuel filters pretty regularly after adding it, depending on the severity. Startron actually dissolves the buggers into the fuel and allows it to be burned off and passed through the filters, but can make the fuel appear darker than usual if it's a bad infection. There is a distinct difference between these two types of products and the answer to the op's question almost entirely rests on this variable.
