Product Overview
A weak transfer pump can cause slow priming, hard starts, hesitation and power loss when the injection system cannot receive a steady supply of fuel.
This pump sits on the supply side of the fuel system and is responsible for keeping fuel available to the injection or carburetion system. A healthy supply pump is especially important during starting, high-load operation and after fuel-filter service.
Key Features & Performance
- Supplies the low-pressure fuel flow required by the engine/injection system
- Helps restore dependable priming, starting and fuel delivery under load
- Built around the mounting and fuel-line layout used by the listed applications
