Lawn & Garden Equipment Engine Fuel Pump Kit 52-559-03-S

Remove and replace fuel pump.

It is bolt on but much has to be removed and then replaced and there is not much room to work in. The part fit and upon successful installation the tractor is back in service. Assembly drawings are good for ordering parts. It would be helpful if there was a online service procedure describing disassembly and reassembly steps. Without this I had to feel my way along and the work did not progress efficiently. There should be standards to diagnose if a part has failed. I just picked the fuel pump and I guessed right. There should be a way to measure when a part is defective.
