I never measured my hoses, but im thinking that the braidded hose is only limited by the connectors and the volume of the hose , (They appear to be close to 5/16,
To the best of my ideas, I really dont believe that someone could make some statement that there line size is best, I really think that is an over statement..
when it comes to the line size being 1/4-5/16-3/8, they would all be the same or unnoticable, the hose is around 14-15 inches i believe,(never really measured the lenght) And that the volum in those sizes and for the lenght are really not a factor under the idea of what the HPOP put out in pressuer not to mention that I think the braided hose is the same size as the factory ones,
If the line was 20 ft long then I could possibly see were it could make a difference, but as long as the balance of the to oil rails are connected to help stabilize the senor more equally then there statement could only be In milliseconds of start up and return to idle, if it can really be measured,
Any chance you could postr a pic of what you did...you got my interest up
