Fuel System

Holley Performance Products has released its new line of billet HP and Dominator In-Line Fuel Pumps, which are designed for use in a carbureted or fuel-injected street, race, off-road and other vehicles.

The fuel pumps are gasoline and diesel compatible and can be used in racing applications with an 18.5-volt charging system up to 80 psi, according to Holley. They have a 100,000-plus mile durability and are fully submersible for in-tank installations.

FAST™ Universal In-Tank Fuel Pump Retro-Fit Kit
Memphis, TN – New FAST™ Universal In-Tank Fuel Pump Retro-Fit Kit makes installing an in-tank fuel pump into a tank without a pump easier than ever.

This Universal In-Tank Fuel Pump Retro-Fit Kit is designed to work with any popular EFI system, including XFI™ and XFI 2.0™. The kit is engineered specifically for retro-fitting in-tank pumps to fuel tanks that were manufactured without pumps. This Universal In-Tank Fuel Pump Retro-Fit Kit includes everything needed to set up and install an in-tank pump (kit requires adequate tank access port hole large enough [3″ diameter minimum] to fit pump through – some older tanks may require custom modifications or an added access port). Once installed, the in-tank pump is automatically cooled by the fuel in the tank, which prolongs its service life. The included Walbro 255 LPH high pressure fuel pump easily flows enough fuel to support nearly any electronic fuel injection system. FAST™ recommends any fuel tank modifications be completed by a professional fuel tank manufacturer or service facility.

FAST™ engineers designed the revolutionary new XFI 2.0™ with a host of improved functions and advanced capabilities specifically for all-out race applications. Because the system is so advanced, ordering one previously required phone calls with EFI specialists. Now, assembling and ordering the next generation of XFI™ is as easy as visiting the FAST™ webpage. The new XFI 2.0™ System Selector walks you through building the perfect XFI 2.0™ Fuel Injection System for your application in five easy steps. First, select whether you want to add Internal Data Logging, Intelligent Traction Control™ or the 16 Injector Option to the XFI 2.0™ ECU. Then select the Main Harness according to your Throttle Position Sensor (TPS) and application. There are even TPS images to help if you are unsure. Next, select the Fuel Injector Harness for your application. Then, select the Ignition Adapter Harness you need. Finally, choose any optional additions you may want such as an Accelerometer Module, Dash/Data Logger or cable extensions. Once completed, you can review the selections you just made and then print a list of the part numbers, buy your new XFI 2.0™ kit directly from the FAST™ webstore or email a list of your selections to a FAST™ technician, along with any questions you may have. Once sent, an EFI specialist will look over your system and respond as soon as possible. Ordering an XFI™ System has never been easier. The XFI 2.0™ System Selector is available for anyone to use at www.fuelairspark.com

The two-barrel 48 IDA, with its superb design and craftsmanship, is the best known of the Inglese™ Weber carburetors. The number “48” indicates it has a 48mm bore diameter and throttle plate, while the IDA suffix indicates that this is a high performance downdraft carburetor.
The 48 IDA design is simple and elegant, with no metering rods, power valves, rubber seals or plastic parts. Its accelerator pump and floats are made from brass, and its throttle shaft rides in precision roller bearings.

Inglese™ 48 IDAs can be tuned to work with nearly any displacement or compression ratio by virtue of interchangeable venturi that permit them to be tuned to flow as much (or as little) CFM as your engine requires. Although 48 IDAs are often described as being more of a race-oriented carb due to a simpler transition circuit than that found in IDF carbs, Inglese-tuned IDAs make a superb choice for both street and track use.
