ABSTRACT
Fuel leakage in the pre-filter bowl of a diesel enginefeed pump is the common problem in the field. The leakage of fuelis mainly due to the method of assembly and design of thecomponents. Though the threaded fasteners are easy formaintenance and low cost in the assembly of the components, theyare not advisable due to its limitation of loosing the threadedfastener under the dynamic loading. A case study has been done inthe industry to reduce the rejection of feed pump due to leakage offuel in pre filter bowl of a diesel engine. In this paper an effort ismade to identify the factors which cause the leakage of the fuel. Itis found that due to deformation in the wire clip and filter bowl iscausing the major problem. Hence analysis of the existing designis made and suggested the improved design using Finite ElementAnalysis.
