FF3003 Fuel Filter + FS1001 Water Separator for Titanium Series
Two filters for the Titanium and Platinum series systems pump: the FF3003 fuel filter and the FS1001 water separator, both on a 1-14 thread. The separator takes the water out first and the fuel filter cleans up what is left, so the pair covers both halves of the job. The fuel filter also carries FF5320, BF7633 and 1R-0750.

Description
Product Overview
This is a two-filter set for Titanium and Platinum series systems pumps: the FF3003 fuel filter and the FS1001 water separator. Both are spin-on cans on a 1-14 thread, and both are replaced at the same service, which is why they are sold together — fitting one and leaving the other is doing half the job with a new filter next to an old one.
The order of work matters. The water separator sits first in the flow and drops the water out of the fuel, both the free water that settles and the emulsified water held in suspension. The fuel filter then works on what is left, holding back the particulate that would otherwise reach the injection pump and the injector seats. On a system that runs a lift pump, the pump is lubricated by the fuel it is moving, so water taken out early is wear avoided at the most expensive part of the circuit.
Neither can is matched to a vehicle on this page. They are matched to the system: the listing states two fuel filters for the Titanium and Platinum series systems pump, and the numbers below are what identifies the correct pair. Read the numbers off the old cans before ordering, because these systems were built in more than one configuration and the wrong can will either not seal or not flow.
Key Features
Cross Reference
The two lists are separate and they do not overlap: a number from the fuel filter side will not bring up a water separator, and the other way round. That matters at the counter, where both cans look similar in a photo and only the number on the side tells them apart. Match each can to its own list before fitting.
Specifications
Applications
Fit the pair to a Titanium or Platinum series systems pump, matching each can to its own number list. The separator goes in the water position and the fuel filter downstream of it; swapping them is the mistake this set is most likely to attract, because the two cans are close in size and both carry a 1-14 thread.
Wipe both filter head faces clean and check that the old gaskets came away with the old cans — a gasket left stuck on a head is the most common cause of a leak on a spin-on. Oil the new rings with clean diesel, spin each can on until the ring touches, then tighten by hand; a wrench distorts the can and is what starts the seep.
Change the pair at 15,000 to 30,000 miles, taking the shorter end if the fuel is dirty or the duty cycle is heavy. Doing them together keeps the separator from passing water onto a filter that is already loaded. Both cans are covered for 90 days against manufacturing defects.
