269 Motorsports 150 PSI Pressure Sensor — Stainless Steel, 0.5–4.5V Output with GT150 Connector

The Lowdoller Motorsports 150 PSI pressure sensor (PN 7990150) is a rugged 0–150 PSI stainless-steel transducer with a GT150 Packard connector, designed for fuel, oil, coolant and back-pressure monitoring in EFI and data-logging systems.

This compact sensor outputs a linear 0.5V to 4.5V signal compatible with common aftermarket ECU and logger platforms. Built with a heavy-duty stainless-steel body and a 1/8" NPT process thread, it provides a simple drop-in option for vehicles, test benches, or custom plumbing where reliable pressure feedback is required. The package includes the GT150 Packard connector, pins, and grommets; a pre-wired cable is available separately for quick installation.

How does this sensor integrate with my EFI or data-logging system?

The 0.5–4.5V output follows the same voltage scaling used by many tuners and loggers, making wiring straightforward. Most modern ECUs and loggers accept this voltage range directly on analog pressure inputs, so you can map pressure values without complex scaling conversions.

• Direct compatibility with Holley, Haltech, Racepak, FuelTech-style inputs
• Uses standard GT150 Packard connector for reliable electrical mating
• Linear voltage output simplifies calibration and mapping
• Prepares easily for aftermarket pre-wired harnesses or custom cables

What physical features make this sensor suitable for automotive use?

The sensor’s stainless-steel housing and 1/8" NPT thread are chosen for durability and common fitment in fluid systems. The compact form factor lets you mount it into fuel rails, oil galleries, coolant lines with available ports or into inline adapters for back-pressure measurements.

• Heavy-duty stainless-steel body resists corrosion from fluids
• 1/8" NPT thread matches typical pressure ports and adapters
• Robust GT150 Packard connector with pins and grommets included
• Small footprint for tight engine-bay or test-rig installations

Which pressure ranges and applications is the 7990150 best for?

Rated 0–150 PSI, this transducer covers a wide variety of automotive pressure checks without overkill for most street, race, and bench setups. It works well where pressures remain below 150 PSI such as fuel rails on high-performance engines, typical oil pressures, coolant system tests, and exhaust or intake back-pressure checks when adapted correctly.

• Fuel pressure monitoring up to 150 PSI
• Oil pressure sensing for most performance engines
• Coolant system pressure checks and leak diagnostics
• Back-pressure and boost-related measurements with proper adaptors

Who is this for? The Lowdoller Motorsports 150 PSI Pressure Sensor PN 7990150 is aimed at tuners, race shops, DIY engine builders, and data-loggers who need a compact, industry-compatible pressure transducer that installs easily and communicates clean analog voltage to ECUs and loggers. If you require a durable sensor with standard electrical scaling, included connector hardware, and broad compatibility with aftermarket systems, this unit is a practical choice. Note: pre-wired harnesses are sold separately; choose the appropriate cable for your ECU or logger input. Always confirm port threads and pressure range suit your intended application before installation.
