Racor RK11-1404 Seal Service Kit – For 900MA / 1000MA Turbine Fuel Filters
Part Number: RK11-1404 (distributor SKU: 62-RK111404)
Brand: Racor
Type: Complete seal service kit for Racor 900 and 1000 Series Turbine fuel filter/water separator assemblies
Fits: 900MA, 903MA, 1000MA, 1003MA, and compatible 900/1000 FE, FF, FG, FH, and MA-series assemblies
Weight: approx. 567 g
Product Overview
The Racor RK11-1404 is the complete seal service kit for Racor 900 and 1000 Series Turbine fuel filter/water separator assemblies, including the marine 900MA and 1000MA families. When a Turbine filter housing is being disassembled for maintenance, seasonal service, or contamination cleanup, this kit renews all the primary seals and related small components in a single package — O-rings, bowl seal, lid seal, drain seals, check-ball components, and water probe/plug seals. Replacing all service seals at once, rather than just the visible lid seal, is the correct approach for a complete housing overhaul and eliminates the risk of leaving aged seals in place.
Note: this is a seal service kit only — it does not include a replacement fuel filter element. If a replacement Turbine element is also needed, order the appropriate element separately for your specific assembly.

- Seals are showing signs of age: hardened, flattened, cracked, swollen, or beginning to seep
- The housing is being disassembled for contamination cleanup or interior inspection
- Performing seasonal commissioning or winterization service on a 900MA or 1000MA assembly
- An older Turbine assembly is being returned to service after extended storage

Installation Notes
- Drain and safely dispose of any fuel in the filter housing before disassembly
- Clean the filter housing, lid, bowl, drain body, and all sealing grooves thoroughly before installing new components
- Never reuse compressed, flattened, or aged O-rings — replace all seals from the kit
- Lubricate new O-rings and seals only with a lubricant approved for use with diesel or gasoline fuel systems (as appropriate)
- Torque all fasteners and the bowl/lid to the specifications in the Racor 900/1000 Series service documentation
- After reassembly, prime the fuel system and inspect all sealing surfaces carefully for leaks before starting the engine
Technical FAQ
Does RK11-1404 include a replacement filter element? No — RK11-1404 is a seal service kit only. It renews the housing seals, O-rings, and check-ball/drain components. Order the appropriate Turbine replacement element separately for your specific assembly.
What is the difference between RK11-1404 and RK11-1952? Racor lists RK11-1952 as a seal kit associated with certain 900/1000 Series FH configurations. RK11-1404 is the broad 900/1000-series seal service kit covering MA, FE, FF, FG, FH, and compatible assemblies. Verify against your assembly’s service documentation if you have an FH configuration.
How do I know if my 900MA or 1000MA needs a full seal service? Common signs include seeping or weeping at the lid, bowl, drain, or water-probe fittings; O-rings that appear hard, flat, cracked, or discolored; or any housing disassembly for contamination cleaning where aged seals would be disturbed and should not be reused.
Can I reuse any of the old seals after cleaning? No — O-rings and seals that have been compressed in service or exposed to fuel should be replaced, not reused. Installing the new seals from RK11-1404 at each housing service is the correct practice.

Parts Desk Insights
The RK11-1404 is the right call when a 900MA or 1000MA Turbine assembly is already apart — the most common mistake is replacing only the lid seal and leaving the bowl, drain, probe, and check-ball seals in place. Those seals are just as old and just as likely to fail, so a full kit replacement at each housing service is always the better approach. The key clarification for customers is that this is a seal kit, not an element kit — they still need to order the correct Turbine element separately. If a customer reports uncertainty about which seal kit fits their assembly, the fastest resolution is to check the model number on the filter head or bowl and cross-reference against the 900/1000-series service documentation. If they have an FH configuration, confirm whether RK11-1952 is more appropriate before recommending RK11-1404.
