Holley carburetor float kits work with side-hung and center-hung Demon and aftermarket Holley carburetor floats, as well as many OE Holley, Ford, Chrysler, GM, Motorcraft, AMC, and Rochester marine carburetors. Offered in brass and Nitrophyl for internally and externally adjustable floats, they're available as primary floats, secondary floats, and secondary floats with notches that include jet extensions. Holley's wedged floats feature a reinforced float bracket assembly that allows more fuel to flow through the bracket—especially when using bottom-feed needles and seats. Technical notes for Holley carburetor float kits: * Wedged floats are designed for oval track use, so the float stays open in turns * The use of brass floats on the secondary side of Model 4160 carburetors factory-equipped with Nitrophyl floats may result in loss of fuel control and flooding if the floats contact the metering plate * You should only install jet extensions and notched floats in rear fuel bowls

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
