Warm up regulator to fuel distributor line
While replacing the wiring harness on my 1983 320i, I cracked the fuel line from the fuel distributor to the warm up regulator. I was unable to find the type of line on ECStuning website, so if anyone knows the type of line it is please let me know.

I think that is #11? That is the supply hose, return hose is #8. You can easily identify these as the have different diameters, supply is a 10mm inner diameter, return 8mm.

Now I just have to figure out why when I turn the key to the start position I get a single solitary click and nothing else.
