269 Motorsports 100 PSI Pressure Sensor - 1/8" NPT with GT150 Packard Connector, stainless steel compact transducer

The Lowdoller Motorsports 100 PSI Pressure Sensor (PN 7990100) is a compact, stainless-steel pressure transducer designed to monitor fuel, oil, or coolant pressure with a 1/8" NPT install and GT150 Packard electrical connector.

This sensor is built for enthusiasts and technicians who need a reliable, engine‑bay ready pressure feedback device. It translates hydraulic pressure into an electrical signal suitable for ECU inputs, data loggers, or aftermarket gauges. Compact size and robust construction mean it fits tight installations while resisting corrosion and vibration in demanding environments.

How does this 100 PSI sensor fit my engine or system?

The transducer uses a common 1/8" NPT male thread, making it straightforward to install into many ports found on oil filters, coolant housings, fuel rails, or dedicated pressure bosses. Its small footprint works well in cramped engine bays and race cars where space is limited. Use a proper sealant or PTFE tape rated for fuel systems to ensure a leak-free connection.

• 1/8" NPT male thread for standard plumbing compatibility
• Compact form factor for tight installation spaces
• Installable in oil, fuel, or coolant pressure ports
• Use fuel-safe thread sealants for leak prevention

Will this sensor communicate with my EFI or data-logging setup?

Yes — the PN 7990100 outputs a proportional electrical signal compatible with most engine management systems and common data loggers. It ships with a GT150 Packard connector plus pins and grommets, so wiring into existing harnesses is faster and cleaner. Verify your controller’s input type (voltage or current) and scaling requirements for accurate readings.

• GT150 Packard connector included for quick integration
• Pins and grommets provided for reliable wiring
• Works with EFI systems, standalone ECUs, and loggers
• Confirm ECU input expectations and scale the signal as needed

How durable and precise is the Lowdoller 100 PSI sensor?

The sensor uses a heavy‑duty stainless steel body to resist corrosion and stand up to vibration in automotive applications. It’s engineered to handle pressures up to 100 PSI, suitable for many fuel, oil, and cooling system ranges found in street and race cars. While designed for robustness, proper installation and wiring help maintain long-term accuracy.

• Stainless steel housing for corrosion resistance
• Rated measurement range up to 100 PSI
• Built to withstand engine-bay vibration and heat
• Durability depends on correct installation and sealing

What comes in the box and what do I need to know before installing?

The package includes the Lowdoller Motorsports 100 PSI pressure sensor (PN 7990100) along with a GT150 Packard connector, pins, and grommets for immediate wiring. No additional adapter is required for systems accepting a 1/8" NPT sensor, but you may need fitting adapters or thread sealant depending on your port type. Always check system compatibility and routing so the harness clears heat sources and moving parts.

• Included: sensor, GT150 Packard connector, pins, grommets
• 1/8" NPT thread — adapters only if port differs
• Use appropriate PTFE or thread sealant for fuel systems
• Route wiring away from extreme heat and rotating components

Who is this for: This pressure sensor is aimed at automotive hobbyists, performance shops, and motorsport teams who need a compact, rugged transducer for monitoring fuel, oil, or coolant pressure. It suits anyone integrating pressure feedback into aftermarket ECUs, standalone data loggers, or custom gauge setups, and it’s especially useful where a stainless steel sensor and Packard-style connector simplify installation and reliability.
