Up here in the North Western suburbs of Chicago most places had nut couplers but no one had 7/16". All had 3/8" and then 1/2". I ordered mine from McMaster but went with the 1 1/2" long ones.
Inertia switch is for fuel pump only. Wire it in series wit the fuel pump relay ground. I also have hidden cut off switches so I can disable the fuel pump and ignition.Apparently, I just suck at hunting for hardware. So I'll keep hunting. Having said that, I know this has been discussed and I've read the threads, but other thank Holde.co.uk, any ideas where to find close to matching style switches to the ones with the kit? I've already posted about this in Chewy's thread, but was wondering if anyone else had any other ideas.
Edit: I've also noticed people talking about not needing the inertia switch with carb'd engines. is the inertia switch only for cutting the fuel pump? I understood it as total car power, akin to a killswitch, no?
