I just R&Red a '90 VE pump to re-seal it, what's there to see that I haven't already seen?
Instead of getting testy with me, try looking at it practically.
Look at a completely and correctly installed set of lines and you will see that the further away from the pump, the less bends and more straighter sections.
This is exactly the way I organized the last set of them that was dis-assembled in a box.

LOOK at the lines on the engine, technically they are NOT the same physical length, though they are bent so as to make them the same VOLUME.
In a LINEAR sense, the distance between 2 physical points, they are NOT the same length.

It depends on your point of view.

say the lines are 3FT long in straight length from the start....
they take 6 lines all equally length and bend them to fit the application there for there the SAME length 3 foot of material is 3 foot of material NO MATTER how you bend it it will never loose or gain length!
if they were different you would retard/advance engine timing to that cylinder

Very Interesting...

Think about it this way. if you have a line that is 1 foot and another that is 3 feet. both can handle the same pressure and transmit the same volume in a rate of time since they are ultimately limited by their diameter. So theoretically the pressure should be the same at both injectors causing them to open at the same time and since pressure is the same dispel the same quantity of fuel. The injection pump is putting out the same pressure/volume to each line obviously, so it should put us back to square one. Im not denying that they are the same length as it appears that they are, i just wonder why.

I think (don't hold me to it) I read somewhere that Cummins actually took into account how the different radius's of the multiple bends would effect volume and overall effective length in designing the lines to be equal to each injector.
