Currently I'm not driving my truck too much, 5200mi last year. My question is; how long (in time not miles) will fuel filters last? I am running a water separator, Wix 33439, a aux. fuel filter, Donaldson P551313 and the stock fuel filter. I was thinking about changing them every two years, but I need advice from someone more knowledgeable than me.
Thanks John

 

Time is not a real big deal with fuel filters. Just go by the mileage or a fuel pressure gauge.

 

Spooler-I thought, perhaps, that they might get "soggy" if left in for two or three years.
Thanks for your response-John
