4150 Quick Rebuild Kit E85/Alcohol

The 4150 Quick Rebuild Kit E85/Alcohol from Quick Fuel Technology is engineered for high-performance carburetor restoration and maintenance on alcohol and E85-fueled racing engines. Built for serious competitors and hot rod builders who demand reliability under extreme conditions, this rebuild kit restores critical sealing surfaces, gaskets, and internal components that deteriorate through extended heat cycling and fuel exposure. Whether you're prepping a dedicated E85 race car or maintaining an established alcohol burner, this kit ensures your 4150-series carburetor operates at peak efficiency without costly replacement.

Quick Fuel Technology engineered this rebuild kit with alcohol and E85 compatibility as the core design principle, accounting for the corrosive and solvent properties these fuels exert on standard rubber and elastomer components. The kit includes precision-molded gaskets, O-rings, and seals formulated to resist chemical degradation from aggressive oxygenated fuels, plus internal transition pieces and needle seats specifically validated for E85 and methanol applications. Compact and lightweight at 0.48 lbs, the kit fits easily in your garage or pit box, with all components organized for straightforward installation on 4150-platform carburetors without requiring complete disassembly or specialized tools.

Mechanics, engine builders, and bracket racers working with alcohol-fueled or E85-converted carburetors benefit most from keeping this rebuild kit in inventory—it addresses the predictable wear intervals that alcohol's dehydrating and corrosive nature accelerates. Stock this kit before each racing season or after extended dyno sessions to avoid mid-event carburetor failure. Compatible exclusively with Quick Fuel Technology 4150-series carburetors and Holley 4150 designs, installation requires basic carburetor knowledge and takes approximately 30–45 minutes with standard hand tools.
