Is the solution to replace the pipes or is there a larger underlying problem? Alternately, is there some type of crush washer that can seal the leak?
The back of the pump has a short adapter fitting just about 2" long that connects the injector line to the back of the pump.
Where exactly is it leaking from and what have you tightened exactly?
You'll need to investigate this in order to fix your leak.
Cranking on the line can damage the compression fit on the adapter end and do nothing to fix a leak that is happening at the other end of the adapter fitting.
Tight is tight and over tightening a fitting that is not leaking will only cause a new leak or worse damage something.
