Locking Fuel Cap

The Kubota 1.5 Ton Locking Fuel Cap (OEM R5511-51120) is a replacement locking fuel tank cap designed for compatible Kubota compact construction equipment. It provides a secure closure for the diesel fuel tank, helping prevent dirt, dust and moisture from entering the fuel system while also reducing the risk of unauthorised access to the fuel supply. The cap is supplied as a complete locking assembly with two matching keys.

Designed for the demanding conditions of construction and plant equipment, the cap provides a tight seal while allowing straightforward removal for routine refuelling. It is used across a range of Kubota compact excavators, wheel loaders and compact track loaders, including selected KX, U, R and SVL models.

IMPORTANT INFORMATION

The locking mechanism and sealing function are both important to the correct operation of the fuel tank. Inspect the filler neck and sealing surface before fitting the replacement cap, removing any dirt or debris that could prevent the cap from seating correctly.

Always check the machine model and serial number before ordering, as fuel tank arrangements can vary between Kubota models and production ranges. The R5511-51120 reference should be matched against the existing cap or machine parts information to confirm compatibility.
