Toyota 1KD / 1GD / 1VD Digital Fuel Rail Pressure Indicator
Watch Your Pump Hit Target Pressure | Suits 6-Pin Rail Sensors
The gauge that answers the question boost and EGT gauges can't: is the pump hitting target rail pressure? This digital indicator monitors the high-pressure pump's output in volts – the missing piece when you're diagnosing smoke, power loss or a tired fuel system.
Why Monitor Rail Pressure?
Excessive smoke can come from boost leaks – but it can just as easily be the fuel pump missing target pressure, forcing the ECU to extend injection duration to compensate. Without a rail pressure reading you're guessing. Alongside boost and EGT gauges, this removes a whole piece of the diagnostic puzzle – and on tuned engines it shows you exactly when the pump becomes the bottleneck.
Fitment
- Suits most Toyota 6-pin rail pressure sensors: Hilux N70, Hilux N80, LandCruiser 79 Series, LandCruiser 200 Series
Does not suit Hilux pre-08/2006 (3-pin sensor) – these are available by request, message us.
Note: bracket colour depends on stock – black or stainless finish.

Frequently Asked Questions
Q: What does the gauge actually read?
A: The high-pressure pump's pressure output as a voltage from the rail pressure sensor – letting you watch whether the pump is achieving target pressure under load.
Q: Will it upset the ECU?
A: No – it monitors the sensor signal, it doesn't alter fuel system operation.
Q: Do I need this if I already have boost and EGT gauges?
A: It's the third leg of the stool. Boost and EGT can both look fine while the pump quietly misses rail pressure – this is how you catch it.
Q: Will it fit my pre-08/06 Hilux?
A: Not off the shelf – early 1KDs run a 3-pin sensor. Message us and we can sort one by request.
