Product Overview
The rail acts as the high-pressure accumulator between the supply pump and electronically controlled injectors. It must contain and distribute high-pressure fuel consistently, making damage, contamination, leakage, or an incorrect rail/sensor configuration a serious fuel-system issue rather than a routine low-pressure repair.
The 1J770-50600 / 1J770-50604 references are the most important fitment identifiers on this component. V2607 and V3307 engines are installed in many different machines, and rail revisions can vary by engine specification and emissions generation.

- High-pressure common-rail fuel distribution assembly
- Matches Kubota references 1J770-50600 and 1J770-50604
- Used on supported Kubota V2607 and V3307 electronically controlled diesel engines
- Application should be confirmed by engine specification and rail part number rather than machine model alone

Before You Order
Common-rail systems operate at extremely high pressure. Do not loosen high-pressure lines while the system is running or pressurized. Match the exact engine specification, rail number, sensor/valve arrangement and line connections before ordering.
Frequently Asked Questions
Q: Is this the low-pressure fuel rail?
A: No. This is part of the engine’s high-pressure common-rail injection system.
Q: Can a rail be chosen just by V3307 engine name?
A: No. V3307/V2607 engines have multiple emissions and fuel-system revisions, so use the complete rail reference and engine specification.
