    Hi everyone,
    I don't know much about plumbing, and even less about plumbing for diesel. I want to level up my knowledge and solidify it with a little project to apply what I learn: modify the fuel system of my inboard diesel to add a diversion system to a fuel polisher. I'm probably overthinking it, but I like to use learning opportunities like this. I'm anticipating there's probably some basic rules about type of pipe selection (material compatibility, pressure sensitivity), valves, components, how to size equipment, connectors and standards, pressures, flow rates, etc? Can anyone give me the rundown of what I should know? Or point me to a good resource?

    ABYC H-33 and 46 CFR Subchapters C and/or T for material and fabrication...design is a little bit more tricky, you as the customer will set a lot of those requirements (i.e. how much you want to polish how fast, standalone vice integral, day tank needs, etc.)
