Aeromotive 12639 is a 10-micron microglass replacement element for a matching reusable filter housing. Choose the cartridge by housing, fuel and pump-side placement; the element is supplied separately from the complete inline filter.
Direct replacements listed by Aeromotive: 12339, 12341. Verify the actual housing and existing element marking before servicing; a shared port size alone does not identify the cartridge. Pressure side of the fuel pump only.

The reusable filter housing, end caps, adapters, mounting hardware and complete fuel plumbing are separate. A housing O-ring is not promised without exact packaging confirmation.
Aeromotive develops performance fuel pumps, regulators, filters, rails, tanks, fittings, controllers, and complete fuel-system components for street, racing, and custom applications. Black Ops Auto Works organizes each listing by exact part number and available application data to support accurate system planning.
What is the 12639?
It is a 10-micron microglass service element for the matching Aeromotive filter housing, rather than a complete inline filter assembly.
Which housings are documented?
The manufacturer identifies 2.5-inch OD × 7-inch-long Aeromotive ORB-12 housings, with direct replacements listed for 12339, 12341. Housing dimensions describe the assembled filter family; they are not cartridge dimensions.
Which fuels are listed?
Gasoline, diesel, ethanol and methanol. Confirm all seals, lines, pump and other system components separately.
Where should this element be used?
Pressure side of the fuel pump only. Select filtration for the actual pump and downstream equipment.
Can it be cleaned?
The 10-micron element is not cleanable; replace it rather than washing and reinstalling it.
Is a housing O-ring included?
The exact current page does not itemize a new housing O-ring. Do not assume the packaging of another cartridge applies.
What does the stated flow mean?
Up to 400 GPH (6.66 GPM) at less than 1 PSI pressure drop. These are manufacturer-listed application/flow conditions, not a working-pressure rating, guaranteed engine output or a measured result for your entire installation.
How often does it need service?
Aeromotive recommends at least annual filter service and closer attention where contamination or use demands it. New systems and severe conditions may need more frequent checks; a calendar interval does not excuse operating with a restricted element.
The current manufacturer page limits use on emission-controlled vehicles to a direct replacement matching OEM specifications.
