larger dia fuel lines

  1. 5.9 w/P7100 fuel line sizes?

    Cummins Tech Section
    I've been reading a tech article that the piston lift pump for the 5.9 P7100 application needs a 5/8" fuel line from tank in applications running up to 2.5k rpm to keep the flow rate at around 2 feet per second for max lift pump efficiency. I'd like feed back on this topic.
