Compatible Models
We do our best to list all compatible models. Although this may be the part you need, your exact model may not appear below.
| Application | Compatible Models / Details |
|---|---|
| Isuzu Engines | 3LA1, 3LB1, 3LD1, 3LD2, 4LB1; compatible 4LE1 applications where this solenoid reference is specified |
| Equipment Examples | Selected Hitachi compact excavators such as EX50U/EX55/ZX55UR and related equipment depending on engine configuration |
Product Overview
The fuel shutoff solenoid moves the injection-system stop mechanism electrically. If its coil opens, the plunger sticks or the supply circuit drops voltage, the engine may crank without receiving fuel or may fail to shut down when commanded.
Isuzu parts references tie 8973295680 to 3LA1, 3LB1, 3LD1, 3LD2 and 4LB1 engines, while equipment-market listings also show compatible 4LE1 applications. The replacement family includes several earlier Isuzu numbers, making the original part number a useful confirmation.

Frequently Asked Questions
What does the solenoid control?
It electrically operates the fuel-off mechanism on the mechanical injection system.
Can wiring problems look like solenoid failure?
Yes. Low supply voltage, corrosion or a poor ground can prevent a good solenoid from moving correctly.
Compatibility can vary by engine, serial number and equipment configuration. Match the original part number and physical configuration whenever possible before ordering.
