Abstract: An automobile engine hose replacement system for providing a customized hose that is connectable between two couplings or nozzles in any automobile engine is provided. The hose replacement system includes a length of hose and a plurality of various size adaptor members. The length of hose is suitable for being cut to any desired length for providing a hose member having first and second ends. Each of the adaptor members is suitable for coupling to either end of the cut hose member in order to selectively adjust the hose diameter at either end. As a result, the hose member may be selectively connected to any pair of nozzles, whether they be of the same size or of differing sizes.
