In high-performance carbureted racing, a momentary drop in fuel pressure can lead to immediate engine detonation and a multi-thousand-dollar repair bill. While a standard dash gauge is great for monitoring, a driver at 150 mph isn't always looking at the needle. The Longacre 40250 Gagelites Warning Light Kit provides an unmissable, brilliant red visual alert the instant your fuel pressure dips below your safe operating threshold.
What sets this kit apart is its fully adjustable range. Unlike fixed switches that trigger at a generic 4 PSI, this professional-grade sender can be custom-tuned via an internal set-screw to activate anywhere between 2 and 7 PSI.
Key Features
-
Adjustable Trigger Point (2-7 PSI): Features a tunable internal set-screw, giving you total control over the exact pressure drop that triggers the alert. Perfect for fine-tuning based on your fuel pump's output and engine demand.
-
Ultra-Bright 3/4" Red Light: Equipped with a large, high-intensity red indicator light designed to be mounted directly in the driver’s peripheral vision. It is impossible to miss, even in direct sunlight or through a dusty visor.
-
Instant Safety Response: Eliminates the delay of monitoring an analog gauge. The light flashes "ON" the millisecond pressure falls below your pre-set limit, giving the driver crucial seconds to kill the ignition.
-
Complete Installation Package: This is a full "plug-and-play" kit. It includes the adjustable 1/8" NPT sender, the 3/4" red warning light, a high-quality wire, and all the necessary terminals and hardware for a clean, professional install.
