269 Motorsports 0–150 PSI Stainless Steel Pressure Sensor — 1/8" NPT, 0.5–4.5V Output for Fuel/Oil/Coolant

The Lowdoller Motorsports 150 PSI Pressure Sensor (PN 7990150) is a heavy-duty 0–150 PSI transducer designed to deliver a 0.5–4.5V output for fuel, oil, coolant or back-pressure monitoring.

This compact stainless-steel pressure sender gives tuners, racers, and performance vehicle owners a reliable, industry-compatible signal for engine management and data logging systems. Built to the voltage scaling used by major ECU and logger brands, it fits directly into most setups where a 1/8" NPT sender is required. The unit ships with a GT150 Packard connector, pins and grommets so you can install a custom-length harness quickly; a pre-wired cable is available separately for plug-and-play convenience.

How accurate and compatible is this sensor with common ECUs and loggers?

The sensor provides a linear 0.5 to 4.5 volt output across its 0–150 PSI range, matching the voltage convention used by Holley, Haltech, Racepak, FuelTech and many other manufacturers. That means straightforward mapping in most engine management systems and loggers without extensive scaling adjustments.

• Voltage span: 0.5–4.5 V linear output
• Pressure range: 0–150 PSI suitable for fuel, oil, coolant, and back pressure
• Compatibility: designed to work with EFI ECUs and popular data loggers
• Installation: maps directly into most calibration tools that expect 0.5–4.5V sensors

What are the mechanical specifications and installation details?

The body is machined from stainless steel for strength and corrosion resistance in demanding engine bay environments. The sensor uses a 1/8" NPT male thread, a common fitting size for fuel rails, oil ports, and coolant passages; thread sealing tape or appropriate PTFE sealant should be used to ensure a leak-free connection.

• Housing: stainless-steel construction for durability
• Thread: 1/8" NPT male — use proper thread sealant
• Connector: includes GT150 Packard connector, pins, and grommets for secure wiring
• Accessory: pre-wired harness available separately for simplified wiring

Can this sensor handle motorsport conditions and repeated use?

Yes — the stainless-steel shell and robust internal design help the transducer withstand vibration, heat cycles, and exposure common in racing and track-day cars. While built for performance use, proper installation and routing of wires protect the connector and preserve long-term reliability.

• Durability: corrosion-resistant body ideal for harsh environments
• Vibration resistance: suitable for engine and chassis-mounted locations
• Serviceability: replaceable connector pins and grommets included
• Note: avoid direct exposure of the connector to continuous fluid spray without additional protection

How do I wire and integrate the sensor into my system?

The sensor uses a Packard GT150-style connector with supplied pins and grommets; this lets you create a custom harness to match your wiring layout. If you prefer a ready-made solution, order the pre-wired cable to minimize installation time and reduce wiring errors.

• Connector included: GT150 Packard housing, pins, and grommets
• Wiring: typical three-wire or two-wire configurations depending on your ECU/logger requirements
• Accessory option: pre-wired cable sold separately for plug-and-play installations
• Tip: label and route harness away from high-heat sources and sharp edges

Who this sensor is for: Tuners, race teams, home engine builders and performance vehicle owners who need a rugged, industry-compatible 0–150 PSI pressure transducer. It’s well suited for monitoring fuel pressure on high-flow systems, oil pressure in modified engines, coolant or manifold back pressure readings, or any application where a dependable 0.5–4.5V signal is required by an ECU or data logger.
