The **Bleed Screw** (or vent screw) is a small but crucial component of the **CAV 296** type fuel filter head (or Lucas 296 type). This screw allows the operator to manually open the circuit to release air trapped in the diesel fuel system (the "bleeding" operation), which is essential after replacing the filter or if the fuel runs out.
Product Details
Part Type: Bleed Screw / Vent Screw
Function: Removing air from the fuel circuit (Bleeding)
Application: Vent Assembly on the Fuel Filter Head
Filter Compatibility: CAV 296 Type (Single or Double)
FIGURE REFERENCE N°: 10
Application Notes
This spare part is compatible with most CAV 296 fuel filter heads that feature the standard vent assembly. The screw acts as a threaded plug that, when loosened, allows air to rise and be expelled from the diesel fuel.
IMPORTANCE: A damaged bleed screw or one that does not seal correctly can cause air to be drawn into the circuit, leading to engine malfunctions. Since no specific cross-reference is provided, compatibility is primarily determined by the standard design of the CAV 296 vent assembly.
