Description
When your Case IH Maxxum starts showing signs of fuel starvation—hard starting, power loss under load, or that frustrating habit of running fine until you really need the power—your mechanical fuel lift pump is probably calling it quits. The diaphragm creates suction to draw fuel from the tank and delivers it at the proper pressure to your injection pump. This Tisco replacement gets your tractor back to delivering the steady fuel flow your diesel demands.
What You’re Getting
- Reliable diaphragm design that handles the constant pressure changes of daily operation
- Direct replacement—no adapters or modifications needed for your Maxxum
- Quality materials that resist fuel additives and temperature swings
- Built-in check valves that prevent fuel drain-back for easier starts
Built for Real Farm Work
Case Maxxum Series (5120, 5130, 5140, 5150, 5220, 5230, 5240, 5250), Case MX Series, and New Holland TSA/T Series tractors are powerful agricultural machines commonly used for large-scale farming operations including grain production, heavy tillage, livestock management, and custom harvesting. Whether you’re running a loader, pulling heavy implements, or tackling long days in the field, these tractors need consistent fuel delivery to keep working hard.
Made to Last
The robust construction handles the constant flexing and pressure changes that come with normal operation. This pump is built to provide the reliable service your Maxxum needs, from cold morning starts to hot afternoon fieldwork. The diaphragm material stays flexible through temperature extremes and resists the additives in today’s diesel fuel.
Installation Notes
This is a straightforward swap—remove the old pump and bolt on the new one using fresh gaskets. Mark inlet and outlet connections before removal – reversed connections cause immediate failure. After installation, you’ll need to prime the fuel system to get all the air out. Most Maxxum tractors make this easy with accessible priming points, but check your manual for the specific procedure on your model.
