How often do I need to change the filter?  (this is our #1 asked question)


This depends; how dirty is your fuel? You may be able to run several months on a spin-on/filter, then all of a sudden, it plugs up due to one batch of dirty fuel. This even happens with race fuels that have sat in tanks too long and collected water.

We recommend to change the fuel filter any time that you change your oil filter. Or, to get some type of time frame; every time you change the oil filter, remove the FST fuel filter and drain it into some type of clear container and let the fuel set; after a short time, look to see if there is any water (it will separate from the fuel)...if the "fuel" looks clear, then put a film of oil or grease on the filter seal and put it back on...if the fuel looks cloudy, change the filter.
