What Alternative Fuel Systems does
Alternative Fuel Systems, Inc. (AFS) is a privately held, Illinois-based distributor and manufacturer of off-road and industrial propane (LPG) and natural gas fuel systems. Founded in 1975 and headquartered in Arlington Heights, the company supplies complete fuel systems, replacement components, and ancillary service parts to original equipment manufacturers and aftermarket customers, with a catalog exceeding 600 fuel system configurations that are 100% tested prior to shipment. AFS manufactures its own line of proprietary custom industrial products—pilot actuated two-stage electric lock-offs, fuel filters, bulkhead filters, inline thermostats, and UL-approved fuel hose—and serves as a major distributor for IMPCO/GFI, Parker (fuel hoses and fittings), REGO (fittings and tank valves), and Bosch (selected fuel system components).
The company's technical differentiator is 50 years of accumulated expertise in fuel system applications, design, emission calibrations, troubleshooting, maintenance, and repairs—a domain specialization it leverages over pure-play distributors. AFS claims the world's largest inventory of fuel system kits and a most diversified parts inventory that supports a 100% fill rate on service parts orders, a metric it positions as central to customer retention. Underlying technology is mechanical rather than digital: pneumatic/electric lock-off valves, filtration, temperature regulation, and certified hose assemblies meeting UL safety standards for fuel handling.
Commercially, AFS operates a direct-to-customer model through an e-commerce storefront at shop.altfuel.com and phone-based enterprise sales at a single Arlington Heights location, with global reach enabled primarily through its role as one of IMPCO/GFI's largest and oldest industrial distributors. Revenue mechanics are hardware-driven across three streams: complete fuel system sales, third-party component distribution, and proprietary product manufacturing. Pricing is not publicly disclosed and is handled via quote per inquiry. The firm employs 1–10 people and is privately held with no disclosed funding, M&A, or ownership transactions.
