## 🔌 Function

Collects separated water and contaminants beneath the fuel-filter element and provides a reservoir for draining.

## ⚠️ Common Signs of Failure

-   Fuel seepage or air entry around the bowl seal
-   Cracking, clouding or impact damage
-   Water-in-fuel warning returning soon after draining
-   Damaged drain-valve threads
-   Bowl that cannot seat squarely on the filter head

## 🛠️ Service Notes

-   Renew the O-rings and seals that belong with the bowl whenever it is disturbed, and check each one is seated in its groove before the bowl is drawn up
-   Wet the seals with clean fuel or a smear of oil before assembly so they slide into place rather than rolling or pinching
-   Tighten the bowl only as the procedure for your engine describes, by hand where specified — over-tightening distorts and cracks a bowl, and a cracked bowl puts fuel into the bilge
-   Check the drain tap or plug is closed and sealing, then fill and bleed the fuel system working from the tank end forward
-   Check the bowl joint for weeping with the system pressurised and the engine running, and drain off accumulated water at the intervals in your engine's service schedule
