KENNE BELL BOOST-A-PUMP INSTALLATION
Remove the driver side rear wheel and inner wheel well liner. The liner is attached with 7MM screws.
The BAP will be bolted to the bulkhead in front of the wheel. Mount it as far to the left as possible to allow adequate clearance for the wheel well liner. You will find that the bulkhead is curved and only 3 screws will fit.
Locate the wire harness for the fuel pump. The large gray wire is the fuel pump power lead. Cut that wire and strip both ends. The hot end of the wire (the end that comes from the front of the car) is soldered (or butt connected) to the red wire with the fuse holder on the BAP. The other end (the end that goes to the fuel pump) is soldered (or butt connected) to the other red wire on the BAP. The BAP is basically just a pass through much like an inline fuse.
Some vehicles have 2 gray wires. One of these wires will turn hot for 3 to 5 seconds when the ignition is turned to the ON position. (vehicle not running) This is the wire to splice.
The black wire is grounded to the frame near the BAP. Crimp or solder the ring connector to the wire, grind some paint off the metal and attach it with a screw.
The remaining wire harness on the BAP contains two wires. These wires will be attached to the boost switch and are fished through the rocker panel up to the front of the car. The easiest way is to remove the small access panel behind the front wheel, push a metal tape measure through the rocker panel until it comes out by the rear wheel. Tape the wires to the tape measure and pull it back and out through the front.
Run the wire up to the power brake booster area. Install two female spade connectors to the wires. Find the boost switch in the package. Screw the barbed fitting onto the switch, using a small amount of sealer. Plug the two wires onto the boost switch. (Polarity does not matter) The barbed fitting is “teed” into the brake booster hose with a piece of vacuum hose. Boost pressure closes the switch and activates the BAP at approx. 3-4PSI.
We want you to have the best experience possible when dealing with us both before and after the sale. You can always talk to a sales manager, the owner and head designer, or one of our techs who is infinitely knowledgeable on how the products operate and are installed. You won’t get a minimum wage customer service rep that knows nothing outside his or her script. You’ll get great advice based on many years of experience every time.
We’re happy to help you with your DIY install questions or product inquiries even after hours. The phones forward to either a Manager or Owner to help with both. Remembering that we are on Pacific time, you can generally get help until 9PM on weekdays and weekends alike. It’s something we started when the company was very young and have found it to be an invaluable resource to our customers.
