Installing a Diesel Priming System on Your Boat

Prime Time

Install a diesel-fuel priming pump, then bleed your diesel.

For all of their advantages over gas engines, diesels have one big disadvantage—they won’t run with even a little air in the fuel system. Sometimes a simple filter change can end up with a mechanic’s visit or an expensive tow home. Many engines incorporate a hand-priming pump, but these can be hard to reach and painfully slow, and they don’t prime primary filters installed between fuel tanks and engines.
