Overview

The Kenne Bell BOOST-A-PUMP is a 40 Amp, 21V plug-and-play fuel pump booster designed for 2015-2026 Mustang V8 and V6 models equipped with a supercharger or turbocharger. It activates only at full throttle or boost, preventing unnecessary fuel system load at idle or cruise.

This device powers some of the most potent street and competition vehicles, enabling big horsepower gains on pump gas. It is reliable, easy to install by cutting just one wire, and more dependable than twin fuel pumps.
Show original supplier description
The Kenne Bell Single Plug & Play BOOST-A-PUMP is a 40 Amp, 21V upgrade designed to significantly enhance fuel delivery for 2015-2026 Ford Mustang V8 and V6 models, particularly those utilizing superchargers or turbochargers. It is capable of supporting up to 1000HP with OEM in-tank production pumps. The design incorporates an exclusive built-in regulator that stabilizes voltage, ensuring consistent performance even with battery voltages as low as 11V. Installation is simplified with a plug-and-play harness, requiring only a single wire splice and a ground connection. The unit does not require any additional computers, software, complex programs, or re-tuning. For the 21V Competition Kit, it is essential to use a Boost Activation Switch (BAS) or Vacuum Activated Switch (VAS), as running at 21V full-time is not recommended for any pump or the Ford FPDM. This kit is specifically for boosting a single fuel pump; dual fuel pump setups require a separate universal dual BAP kit (PN: KB89063). Note that 2024 model years are not currently unlocked for tuning using a BAP.
