Restore function to a tired fuel pump

For 50 years Sierra has been producing parts engineered to meet or exceed the specifications of marine engine manufacturers. Boaters and technicians can be assured a Sierra part will fit and restore function.

Fuel pump kits include gaskets, springs and diaphragms to rebuild mechanical fuel pumps used on Chrysler, Mercury and Mercury Sport Jet engines. Everything you need is included. We caution mechanics of the small spring loaded components in these pumps that can be lost during the rebuilding process.

Key Features

  • Sierra rebuild kits meet or exceed manufacturers’ specifications
  • Complete kits are designed to restore function
  • Backed by SeaStar Solutions Limited Two-Year Warranty
