This filter is to be used as a direct replacement for your FASS Fuel Systems Titanium Series Fuel Filter part# FF-3003. This filter can also be used to replace the FWS-3003 on the Titanium Series System only. It is suggested this filter is changed every 30,000 miles.
Note* If you have an older FASS Platinum Series Pump (Single Filtered Unit) we do not suggest using the FF-3003 as a replacement for the FWS-3003. That unit requires a dual purpose fuel/water seperator.
