Bowling Green, KY – Racing and performance enthusiasts all over America are taking notice of E85 as a viable fuel thanks to its terrific 105 octane rating, but the special requirements of E85 might limit its use in high performance cars. The fuel system specialists at Quick Fuel Technology have solved that problem with their new 750cfm E85 performance carburetor.

E85 requires more fuel flow then conventional gasoline, so Quick Fuel calibrates the dedicated billet metering blocks (also available as a separate kit, part no. 34-106) and adjusts air bleed sizes and power valve settings at the factory for easy tuning. Special bullet type Stainless Steel needle and seat assemblies prevent sticking caused by contaminants in the fuel. Since ethanol can deteriorate rubber components, special E85 resistant GFLT accelerator pump diaphragms are used in the carb. The QFT® aluminum fuel bowls are specially coated for corrosion protection, specialty composition floats are alcohol resistant and have a longer stainless steel hinge for improved leverage to close the larger needle and seat.

These high performance carbs feature a billet throttle body with a “multi-link” tunable mechanical secondary activation. Teflon™ coated throttle shafts feature low profile button head screws, and stainless steel throttle plates. Quick Fuel equips their E85 carbs with dual inlets for superior fuel flow and clear sight windows for easy float level adjustment.


This carburetor is presently available using part no. Q-750-E85.
