Did not say that it controls the pressure of injection. Go back and re-read my post.Also the ID of the Fuel injection Lines dose not control the pressure of Injection. It is the amount of spring tension in the Injector that does that.
OK I changed the controls to create.Did not say that it controls the pressure of injection. Go back and re-read my post.
And watch it. I'm just dumb enough to get into an internet debate over fuel lines.
When Plunger inside of one of the Elements moves (when it not in the shutoff position) X amount of Fuel is going to move through the Fuel Injection Line and into the Injector.Let's see if I can make this simple enough for you:
The injectors on a 617 5-cyl. turbodiesel open at what, ~1900 psi.?? So if there is less than 1900 psi., (or whatever the spec is), being supplied to the injector, it does not open, correct? Your car does not run. It is a paperweight.
How do you suppose that Mercedes, (or anyone else), gets over 1900 psi. flowing to the injectors? By forcing liquid through a small diameter tube. Think about the way that the vascular system works in the human body. How it supplies even blood pressure to various parts of the body that are varying distances from the pump. (Your heart). By using smaller and smaller tubes, (veins), as the distances grow and gravity must be overcome. This is also the way that engines supply even oil pressure to various moving parts, by forcing oil through differing sized tubes (galleys/passageways). The ones to the cam(s) are very small if they are on the top of the engine. Think about your municipal water supply and the size of the water main under the street compared to the size of your indoor plumbing. Think about the nozzle on your garden hose. Now think what kind of pressure you'd have if you hooked-up a fire hose to your garden hose bib somehow. Or what kind of pressure a 617 diesel would have to the injectors if Mercedes used much larger tubing with the same size (volume) pump.
Now go back and read my original post regarding tube size, again.
FWIW, I believe the people that say that a piece of bent fuel line will work fine. I wanted the factory tool. I like good tools. I'm funny that way. And thanks especially to GregG for selling me one.
