Holley Easy Level Fuel Level Senders
Holley Easy Level fuel level senders use LiDAR technology to precisely measure the depth of fuel remaining in your tank and work with all Classic Instruments' fuel gauges, including short-sweep, full-sweep, and selectable ohm range fuel gauges. They also work with many other gauge brands. Compatible with tanks ranging from 4 to 39 in., setup is a breeze with the on-board buttons. Easily set empty and full tank positions, with reserve, right on your workbench before installing and then set the empty, half, and full positions on the gauge. The desired dampening rate is adjusted with dip switches right on the unit to reduce fuel slosh and gauge bounce by adjusting how fast or slow the gauge reacts to the fuel level change. Upgrade Classic Instruments' gauge sets and other brands to capture the benefits of Laser imaging, Detection, and Ranging (LiDAR) technology with Holley Easy Level senders. This exciting and innovative automotive application replaces vulnerable moving parts with a hi-tech laser. Besides the problems encountered with float setup, hitting baffles or tank wall, Easy Level eliminates having to set up the float-type sender, saving time and effort. Features: * Quickly reads fuel levels with zero contact * Easy installation with no moving parts; popular 5-bolt flange * Long life sensor and no failing floats * Easy to program the level of any tank and electronic gauge * Bolt Circle Diameter (BCD) is 2.122 in. * Output is a PWM signal for 12 V applications (10 to 20 V maximum) * Mounting hardware and rubber gasket * Maximum operating temperature of 185 degrees Note: Does not work with OE-style gauges that utilize an ohm only input

Racepak Analog Pre-Programmed V-Net Modules With Sensors
Racepak's Vehicle Network (V-Net) is a "smart data" transfer network able to transmit multiple signals from sensors over a single cable. The key to the V-Net system is the modular connectors that attach each of the devices to the main cable. For a function or component to be monitored on the V-Net, the signal from that device must pass through a sensor and its module (essentially a miniature computer) that identifies and retrieves only the proper incoming signals and allows other signals to pass through. The sensor measures the input from the function or device (i.e. rpm, pressure, temperature, etc.), while the module converts the signal so it can be transmitted over the V-Net. Racepak analog pre-programmed V-Net modules with sensors are programmed to collect specific data and are ready for plug-and-play installation on the V-Net cable. Browse through the various types to determine which functions or components you want your V-Net system to monitor.
