The Carter pump is one of the better electric fuel pumps, and well suited for a Weber carb application. The Bosch pump is NOT suitable for the Webers, as they need a maximum of 4 psi, and even the Spica pump is designed for up to 20 psi. The L-Jetronic pump is designed for 42 psi. Any EFI pump will cause major flooding on a Weber carb.
