About ASNU & Ace Fuel Systems

History of Ace Fuel Systems

In 1985, in Columbus, KS, the Ace Fuel Systems product line was born within the Ace Electric Company, which was part of Echlin Inc. Ace Electric supplied products to rebuilders of automotive electrical systems across the U.S. Soon thereafter, Ace Fuel Systems began supplying components including clutches, transmissions, water pumps, and carburetors to additional rebuilder markets.

Ace Fuel Systems was eventually supplying over 6000 carburetor components to over 600 dedicated carburetor rebuilders across the U.S. and Canada. Ace Fuel Systems did not sell to the traditional market but sold components strictly to the businesses that rebuilt complete carburetors for sale to re-distributors or retail. Ace Fuel Systems then added high-performance carburetor components to its product line and began distributing to performance modifiers who built carburetors for specific performance and competition engines.

In 1994, Ace Fuel Systems became the first distributor for the ASNU Fuel Injection Equipment. This created a new market in the US to test and recondition fuel injectors off-the-vehicle. St. Louis, Missouri-based GSI purchased Ace Fuel Systems in 2013 as a complement to its Tomco Fuel and Emissions business which sells carburetor components and kits.

ASNU is a fuel injector cleaning and testing system developed in the early 1980s by Alan Skovron in Australia. It was the first system to return fuel injectors to their original condition consistently.

ASNU was developed in response to the need for a better way to clean fuel injectors in the Australian market, where lead-based fuel was causing injectors to foul up and clog. Alan Skovron experimented with different cleaning methods, including ultrasonics, and eventually developed the ASNU system.

The ASNU system uses ultrasonics to clean fuel injectors and a flow bench to test their performance. It is a very effective system, and it has become the preferred choice of professionals in the motorsport, marine, and motorcycle industries, as well as other industries where high-performance fuel injection is critical.

Although many other companies have tried to develop competing systems, ASNU is still the world leader in its field. This is because ASNU is a reliable and durable system backed by experts who can always provide support.
