injector line interchangablity

[tom yuenkel]

I have a 91 burb 6.2l and I bought some used injector lines to replace a rusted pair. They are off a db2 pump but have smaller cross sectional hole. I assume this would affect timing and can't be used. So I want to know does the line set always matched the pump or can complete sets be interchanged as long as the lines come off the same pump type.

What were these lines pulled from? You mention a DB2 pump, but there are many many different DB2 pumps that work on different engines, not just the 6.2.

If you pulled the lines from another 6.2, could you describe the cross section that's different? Do you mean that the routing of the lines are different, affecting the overall length of the line?
