Product Overview
If Case IH JX-series tractors using the 504090936-type lift pump starts normally but falls flat under load, needs excessive cranking after sitting, or repeatedly loses prime, the supply side of the fuel system may not be keeping up. A weak lift or feed pump can move enough fuel at idle yet fail to maintain flow when the engine is working.
Check the tank pickup, hoses, filter, and air leaks before condemning the pump. If those items are clear and fuel delivery is still weak or inconsistent, replacing the pump can restore steady supply to the injection or carburetion system.
