CIS fuel line DIY'er.......

SigeKat,

If you have the experience and expertise to build CIS fuel lines go ahead do it as a project. Unfortunately, you seem to know very little with the system and not a good idea to play around with these fuel lines. Your system fuel pressure is anout 70 psi. +|- 5 psi. and your FP is capable of delivering 100 psi. This is not like the carburator system where you could just use micro clamps.

What is wrong with the current fuel lines? It is prudent to replace these old fuel lines with new ones that are built well and done right. If the old fuel lines are not leaking and still in good working condition, I would leave them for the moment until you are able to replace them with the properly built fuel lines.
