Fuel Pressure Sensor
This page provides detailed information about the FuelTech 0-150 PSI Pressure Sensor used in the Honda RC51 custom ECU build, including its specifications, connector details, wiring, and visual references.
FuelTech 0-150 PSI Pressure Sensor Overview
While a fuel pressure sensor is not mandatory for ECU operation, it is highly recommended for optimizing engine performance and ensuring safe operation. The Honda RC51’s stock fuel system is a regulated return-style system, operating at approximately 50 PSI. Adding a fuel pressure sensor, such as the FuelTech 0-150 PSI sensor, is fairly straightforward and provides valuable real-time data for monitoring fuel pressure. In this example, I used a FuelTech 0-150 PSI sensor (Part #5005100020-BLK), but any fuel-compatible pressure sensor can be used, provided the input is correctly configured in FT Manager.
FuelTech 0-150 PSI Pressure Sensor Specifications
The FuelTech PS-150 Pressure Sensor (Part #5005100020-BLK) is designed for accurate and reliable pressure readings in the range of 0-150 PSI.
Connector Data
The FuelTech PS-150 Pressure Sensor uses a 3-pin connector (Delphi: 12065287) for secure and reliable data transmission to the engine management system. The connector kit ensures proper integration with the RC51’s wiring harness. Below are the details for the connector kit:
| Component | Part Number |
|---|---|
| Pan Vacuum/Pressure Sensor 3-Pin Connector Kit | Delphi: 12065287 |

ECU Setup
ECU configuration for the FuelTech 0-150 PSI sensor is very straightforward. Follow the steps below and select the predefined sensor configuration.
- Open FT Manager.
- Navigate to Sensors and Calibration.
- Click on the Inputs tab.
- Locate your Fuel Pressure input field.
- Select the correct default sensor parameter.
Physical Placement
Since there is no OEM sensor for fuel pressure, I added the sensor to the main fuel feed line. Refer to the Fuel Lines documentation for details.
Wiring Diagram
The FuelTech PS-150 Pressure Sensor uses a 3-pin connector with the following pinout: Pin A - Ground, Pin B - 5V, Pin C - Signal. Wiring is straightforward and can be connected to any available white input on the ECU. Refer to the FuelTech manuals for additional details if needed.
