Alternative Fuel Systems Inc.

Gaseous Fuel Injectors

After nearly 15 years of production,  the original AFS Gs Series Fuel Injector line has been discontinued.   We wish to  thank all of our fuel  injector  customers for their  support  and business over the past many years.

For those looking for a quality fuel injector replacement to the Gs, we recommend the new generation IMPCO Gs2 series injector.

Inquiries for the IMPCO Gs2 series can be made through Bill Dauley at
