Holley EFI analog display gauges use digitally-delivered information over Holley's sophisticated CAN bus or wire directly to your sending unit, providing your ride with a classic readout. Those using the bus get their data from the Holley ECU, meaning that you don't have to run wires all over the vehicle. All you have to do is run a single cable to the ECU and then daisy-chain the rest. Holley analog gauges are available to monitor a variety of automotive temperature and pressure functions, along with programmable fuel level and voltage options. Product features include: * Available with black face with white lettering or white face with black lettering. * LED dimmable backlit design with red pointers makes them easy to read day or night * All gauges are electric style and may include sending units depending on gauge type * Pointer is driven by either a high-torque internal stepper motor or internal microprocessor (depending on application) to ensure accurate movement in street and racing conditions * CNC-machined billet aluminum bezels with an anodized finish on some models * Threaded bodies allow a single bezel nut to hold the indicators firmly in place * Bezels are threaded for easy replacement with multiple bezel options available * Each is tested to ensure a top-quality, accurate gauge

Holley EFI fuel pulse dampers act in tandem with the fuel pressure regulator to further control the fuel pressure in an EFI system. They act to smooth out the pressure pulsations caused by the injectors opening and closing as well as the fuel pump operating. These pulsations happen so quickly that in many cases they can't be identified with an analog gauge but can cause issues with fuel delivery to the engine. Options include: * Direct-mount or inline mount * Multiple inlet/outlet dimensions * Standard or extended fuel pressure range * Male or female threads Features: * Engineered to stabilize pressure pulsations caused by the injectors opening; ideal for applications with large fuel injectors and high-volume fuel pumps * Compatible with any fuel; full anodized billet aluminum construction with stainless steel springs and fluorosilicone diaphragm * Fittings included for damper/regulators and direct-mount dampers * 1/8 in. NPT port on body of damper/regulators and inline dampers for easy installation of mechanical pressure gauge or pressure transducer * Vacuum fitting and one foot of hose included with all dampers for vacuum referencing

When installing an LS7 with a dry sump system into your project, you'll need to modify a few items on the engine before installation of the wet sump system. The Holley dipstick drill guide is a great aid in aligning the new oil dipstick location. LS dry sump engines have the dipstick in the remote oil tank. The boss in the block that is typically used for the dipstick is not drilled. When converting to wet sump, the boss must be drilled. This boss is parallel to nothing else—and you only get one shot at the hole. Holley has developed an easy guide to help locate the bit during the drilling process. Using two nearby threaded block holes, the guide creates easy alignment for a hand drill to exactly drill the hole GM would have for a wet sump application. An innovative drill chip slot allows chips to be vacuumed during the drilling process. Features at a glance: * Allows easy drilling of dipstick hole in dry sump blocks when converting to wet sump applications * Self-aligning and locating * Drill chip evacuation port * Machined billet steel construction * One-piece design
