Inline Fuel Filter 879884T for Mercury 30 35 40 50 60 HP 4-Stroke Outboard Engine — Australia Local Warehouse
Inline Fuel Filter 879884T for Mercury 30 35 40 50 60 HP 4-Stroke Outboard Engine — Australia Local Warehouse
Product Overview
Inline fuel filter for Mercury four-stroke outboards from 30 HP to 60 HP, packed at 150 x 100 x 50 mm and weighing 103 g. It replaces Mercury 35-879884T and 879884T and crosses to Sierra 18-79965. The filter sits in the fuel line between the primer bulb and the engine, catching water and grit before they reach the fuel pump and the injectors. Dispatched from our Australia local warehouse.
These 30 to 60 HP four-strokes are the most common engine on an Australian runabout, and most of them are fed from a portable tank that sits in the sun. Once the element loads up, the engine leans out under load, idles rough and loses top end, and on EFI models the debris that gets past it is what blocks an injector.
It is a service item, not a part you wait to fail. Change it with the engine oil and the fuel system stays clean for the price of a couple of litres of fuel.

Ethanol and Water in Australian Fuel
| Fuel Situation | What It Does to the Filter | Action |
|---|---|---|
| E10 ethanol blend | Absorbs water, the element swells and restricts flow | Change more often than the manual says |
| Fuel sat in the tank over winter | Phase separation leaves water at the bottom | Drain the tank, fit a new filter |
| Portable tank in the sun | Condensation forms on the tank walls overnight | Check the bowl, change the filter |
| Refuelled at a marina with old stock | Grit and rust from the storage tank | Change after the first trip on that fuel |
| Engine leans out at wide open throttle | Element already restricted | Change the filter before touching the pump |
Fitting Notes
| Step | Action |
|---|---|
| 1 | Clamp the fuel line, these systems are gravity fed at rest |
| 2 | Note the arrow on the filter body, fuel flows towards the engine |
| 3 | Release the clips and pull the old filter off, keep a rag underneath |
| 4 | Inspect the fuel for water or debris before fitting the new one |
| 5 | Push the new filter on in the arrow direction and refit the clips |
| 6 | Prime the bulb until firm and check both connections for leaks |
| 7 | Start the engine and check again after it has run under load |
