💡 What makes a reed switch fuel sender better than traditional float arms?
Choosing the right sensor technology improves accuracy and reduces maintenance cycles on boats and trucks.
A reed switch sender eliminates wear-prone contact points, keeping resistance consistent over years of vibration.
You avoid frequent gauge jumps and electrical noise that plague older swim-arm designs.
These handy units deliver steady signals straight to your dashboard monitor without signal degradation.
- Select open circuit resistance values to match your gauge specifications for accurate empty and full readings.
- Mount the unit securely using the 5-hole pattern to minimize stress from engine vibration and wave action.
- Maintain probe clearance by measuring tank floor distance and allowing space for the float arc during refueling steps.
