This kit is available without a bottle (05122-NBNOS).
The EFI kits are designed for use with engines that are basically stock. A stock fuel pump should be adequate, however many pumps decline in performance over the years and it is important to have a fuel pump that meets NEW specs. Use only premium grade pump gasoline (92+ octane) or unleaded racing fuel. In many instances, a high output ignition and free-flowing exhaust system may benefit performance. Do not use aftermarket chips or other devices that advance ignition timing, as detonation may occur.
