Fuel System Upgrade

This Fuel System Upgrade is brought to you by AutoDirectSave for your Chevy / GMC.

Boost Fuel Delivery By 50% - The Easy Way

An ingenious, reliable yet simple solution to your fuel system needs. Just tap into your existing fuel pump wiring. Imagine 50% more fuel delivery and horsepower without the hassle and expense of draining and removing the gas tank, tapping into fuel lines or adding a noisy in-line pump - and it doesn't heat the fuel up.

The BOOST-A-PUMP is fully adjustable from 1% to 50% with the mere turn of a dial, so pump output can be varied to match your engine's needs. No longer are you "locked in" to a fixed pump capacity and/or pressure. It activates ONLY at full throttle (naturally aspirated) or at 3 psi (turbo or supercharged). And it acts as a voltage regulator by compensating for any and all system voltage fluctuations.

Until now, fuel delivery could only be adjusted through the use of a pressure regulator, or an in-line fuel return shut off valve (FMU). Unfortunately, the regulator also locks you into a richer and higher pressure at idle and part throttle which can affect driveability and emissions. The FMU limits you to a fixed wide open throttle pressure.

• Doesn't heat up fuel like larger inline or intank pumps.
• No octane loss (gas will begin to boil at 95 degrees).
• Used with all Kenne Bell Supercharger Kits.
• Increases existing fuel pump capacity up to 50%.
• Easily installed. Uses stock wiring. No fuel line modifications.
• Adjustable from 1% to 50% - ON DEMAND from driver's seat.
• Variable Output Cockpit Controller mounts under dash.
• No batteries to run down, replace or let you down.
• Eliminates expensive and time consuming fuel tank removal.
• Works with any pump full or part-time.
• Activation vacuum or pressure switch included in kit.
• Compensates for reduced voltage (lower pump output) when lights or other accessories are on.
• Maintains consistent pump output regardless of battery voltage (down to 10 volts).
• Optimizes Air/Fuel Ratio and horsepower by matching the engine fuel requirements.
• Quiet operation. Not NOISY like in line pumps.
• Improves gas mileage if vehicle now running on high idle fuel pressure.
• Maintains stock fuel pressure at idle and part throttle.
• Controls WOT fuel pressure with return line shut off valves (FMU,FSB).
• Maintains constant output voltage to pump within 1% from 10 to 12.5 battery voltage.
• Doesn't affect pump life.
• Ideal for any Nitrous System.
• Anodized red aluminum.
• Fused circuit protection.
• Works on any car, truck, or boat with 12V electric fuel pump.
• Compact size, lightweight (less than 2 lbs.).
