Abstract: Fuel leakage in the pre-filter bowl of a diesel engine feed pump is the common problem in the field. The leakage of fuel is mainly due to the method of assembly and design of the components. Though the threaded fasteners are easy for maintenance and low cost in the assembly of the components, they are not advisable due to its limitation of loosing the threaded fastener under the dynamic loading. A case study has been done in the industry to reduce the rejection of feed pump due to leakage of fuel in pre filter bowl of a diesel engine. In this paper an effort is made to identify the factors which cause the leakage of the fuel. It is found that due to deformation in the wire clip and filter bowl is causing the major problem. Hence analysis of the existing design is made and suggested the improved design using Finite Element Analysis.
