Probably a really stupid question but want to make sure I don't get a leak. I am fitting a new rubber fuel line between my petcock and filter, the hose is 8mm (I/D) x 15mm (O/D). What size of clip do I use and what is the best type of clip to use.

 

The clip is for added security. The hose should fit snug without (but don't dare run it like this). You should be able to find them at an auto-parts store.
