Product Overview
Inline fuel filter, a fuel system part for Honda four stroke outboards from 35 HP to 90 HP. It replaces Honda 16900-SA5-004 and crosses to Sierra 18-7786 and Mallory 9-37952, and it is a plastic bodied filter with a paper element and a cotton pre filter, fitted in the fuel line between the primer bulb and the engine. One filter is supplied. Shipped from our United Kingdom local warehouse.
The clear moulded housing is the useful part on a British boat. It lets you see water and dirt sitting in the bowl before either reaches the carburettors or the injection system, and on E10 petrol there is usually something to see.
It fits the BF35A and BF45A from 1992 to 1997, the BF40 and BF50 from 1998 to 2008 and the BF75 and BF90 from 1997 to 2006. A restricted filter shows up as a motor that idles cleanly but starves at 4,000 rpm, or one that will not hold full throttle after twenty minutes of running.

E10 Petrol and the Honda Inline Filter
| What E10 Does | Effect on the Fuel System | What To Do |
|---|---|---|
| Ethanol absorbs water from the air | Water collects in the filter bowl | Drain the bowl, renew the filter at the service interval |
| Ethanol attacks old rubber lines | Black particles reach the element | Renew the fuel line with ethanol rated hose |
| Fuel left in the filter over winter | Ethanol and water separate in the bowl | Drain the filter before lay up |
| Long periods between trips | Fuel goes stale and gums the element | Fresh fuel each trip, filter each season |
| Fuel stored in an unsealed can | Water content climbs within weeks | Use a sealed can, keep it full |
| E5 from a marina pump | Less water pick up, same dirt | Same service interval, less bowl water |
Water in the Filter: What It Looks Like
| What You See | What It Means | What To Do |
|---|---|---|
| Clear droplets sitting under the element | Water separated out of the fuel | Drain the bowl and renew the filter |
| Milky or cloudy fuel in the housing | Water mixed through the petrol | Drain the tank, check the filler cap seal |
| Brown sludge on the element | Ethanol gum and old fuel | Renew the filter, clean the carburettor bowls |
| Black specks against the paper | Fuel line breaking down inside | Renew the line and the filter together |
| Filter bowl empty after priming | Air leak at a clip or the bulb | New clips, check the bulb non return valve |
| Clean element, motor still starves | Restriction elsewhere, not the filter | Check the pickup screen and the primer bulb |
Winter Lay Up on a British Mooring
| Storage | What Happens to the Filter | What To Do |
|---|---|---|
| Motor left on the boat over winter | Condensation forms in the housing | Drain the filter, run the carburettors dry |
| Boat under a cover, unvented | Damp air keeps the element wet | Ventilate, remove the filter over winter |
| Fuel left in the tank for five months | Ethanol separates, water sinks to the filter | Fill the tank, add stabiliser, drain the filter |
| Frost below 0 °C with water in the bowl | Water freezes and cracks the plastic housing | Drain the bowl in October |
| Salt spray on the housing fittings | Clips corrode and seize on the spigots | Grease the clips, fit new ones each season |
| First trip in April | Stale fuel reaches the element first | New filter before launch, not after |
Fitting Notes
| Step | Action |
|---|---|
| 1 | Check the old filter body for the number, later Honda four strokes use a different cartridge |
| 2 | Note the flow arrow on the housing and fit the new one the same way round |
| 3 | Check the fuel line either side for hardening or cracks while the filter is out |
| 4 | Fit new clips rather than reusing spring clips, the plastic spigots crack under old metal ones |
| 5 | Prime with the bulb and check both joints for weeps before starting |
| 6 | Start the motor and let it idle, then check the bowl has no air bubble at the top |
| 7 | Change the filter at the service interval, an old element starts passing dirt as it breaks down |
| 8 | Run at planing speed and confirm the motor holds full throttle, a starve shows there first |
