The fuel pump features an external adjustment screw, allowing for easy adjustment of the fuel pressure to meet the specific requirements of your aircraft's engine. This external adjustment feature eliminates the need for internal modifications or disassembling the pump when adjustments are necessary.

The Lycoming LW-12098-0-100 O-235 fuel pump, part number 74225, is a high-quality, dependable component that is essential for maintaining the optimal performance of your aircraft's engine. It is manufactured to the highest standards and is designed to provide years of trouble-free service.

In summary, this fuel pump is a vital part of your aircraft's fuel delivery system. Its durability, efficiency, and ease of adjustment make it an excellent choice for maintaining the performance and reliability of your Lycoming IO-235 series engine.
