I made the mistake of ordering a few of these premade lines to plumb in my mc/line lock/ and valve. It makes it extremely easy to loop a soft line and hook it up over bending NiCop. BUT- once you do you will want to replace all the silver stainless lines with black coated. Ordered half a dozen so far now I need that many more to plumb my remote sensor block. Probably order a bunch of -4 for engine.
