What is the correct fuel pump for my '53 1 ton panel? It has a 55-57 235 in it right now and the current pump is a glass bowl. I like the glass bowl and would like to get another but the only one I see lists an application of 47-51. My current one went out on me today. I want to make sure it mounts to my engine correctly, works correctly and the fuel lines are routed the same.
