Lowdoller Motorsports 100 PSI Pressure Sensor - Heavy-Duty Fuel/Oil

Our review of the Lowdoller Motorsports 100 PSI Pressure Sensor finds it best suited to enthusiasts and technicians who need a reliable, compatible pressure sender for fuel, oil, or coolant systems. The single biggest reason to buy is straightforward: this sensor combines a heavy-duty stainless-steel body and a standard 1/8' NPT thread with a 0-100 PSI range and a 0.5V to 4.5V output, making it an easy drop-in for EFI and data logging systems. It is especially valuable when a compact, durable pressure sensor with a Packard-style connector is required.

Key Features

• 100 PSI range: Covers typical fuel, oil, and coolant pressure applications so a single sensor can be used across multiple systems.
• Stainless-steel body: The heavy-duty construction resists corrosion and handles under-hood conditions for longer service life.
• 1/8' NPT thread: The common thread size simplifies installation into standard ports without adapters in many engines and fittings.
• GT150 Packard connector included: The supplied connector, pins, and grommets allow a cleaner, factory-style electrical connection when paired with a pre-wired cable.
• 0.5V to 4.5V output: Standard analog output works with most EFI systems and data loggers for straightforward integration and reliable readings.

Who It's For

This sensor is aimed at DIY mechanics, race teams, and tuners who need a durable, compatible pressure sender for fuel, oil, or coolant systems. It is especially useful for anyone building or maintaining EFI installations or connecting to aftermarket data logging gear because of its voltage output and connector compatibility.

Those who should look elsewhere are users who require a pre-wired harness included in the kit, sensors with ranges outside 0-100 PSI, or systems that need a different thread type than 1/8' NPT. Also consider a manufacturer-specific sensor if an OEM plug-and-play replacement is required without any wiring changes.

Pros & Cons

Pros

• Durable stainless-steel body provides long-term resistance to corrosion and physical wear.
• Includes GT150 Packard connector, pins, and grommets for a secure electrical connection with a matched cable.
• Works across EFI and data logging systems thanks to a standard 0.5V-4.5V output and common 1/8' NPT thread.

Cons

• Pre-wired cable is sold separately, so additional purchase and wiring time may be required for a complete install.

Specifications

Our Verdict

The Lowdoller Motorsports 100 PSI Pressure Sensor is a practical, value-oriented choice for anyone needing a robust, compatible pressure sender for fuel, oil, or coolant duties. With a stainless-steel body, common 1/8' NPT thread, and included Packard connector hardware, it presents solid functionality and compatibility for EFI and data logging setups, though buyers should budget for a separate pre-wired cable if they want a ready-to-install harness.

Frequently Asked Questions

Is the sensor compatible with common EFI systems?
Yes. The 0.5V to 4.5V output is compatible with most EFI systems and aftermarket data loggers.

Does the kit include wiring?
No. The sensor includes the GT150 Packard connector, pins, and grommets, but a pre-wired cable is sold separately.

What thread size does it use?
The sensor uses a standard 1/8' NPT thread suitable for many engine and fuel system ports.
