I was wondering if it would be alright to put some heat shrink tubing on the wires. I would much rather solder them together and then layer them up with heat shrink, but I didn't know how the heat shrink tubing would hold up to the gas? I let a piece sit in gas over night to see what would happen and it didn't seem to effect it in any way. Long term exposure might be different however. Thanks

well it is rubber so it will get dried out after a while. i have a installed a few those with the kit and it works fine

Alright thanks. Maybe I'll just use the crimps then.
