Mine is starting to crack at the end where it plugs into the regulator, and I suspect it might be leaking and causing me to run smellably rich. Can I just get any normal line that will fit snugly, or do I need a line with the fancy connector head thingy? If so, is it a parts store item, a dealership item, or a junkyard item?

 

It's nothing special except it's a 90* fitting. Don't try bending a piece of vacuum line around and have it kink on you or the regulator will see no vacuum.

 

where can i get those 90° fittings?

 

Junkyard or probably Napa.

 

Actually you can use regular vacuum line just make sure you have enough length to smoothly curve around to the regulator without kinking or restricting it.
