Not even needed in my experience. I’ve had (4) rigs of this generation to date. As long as you keep the level between the overflow tank level indicator lines.

Just to clarify, the hose size I mentioned was the line (#12) between the reservoir and radiator. If you’re looking for the elbow/hose off of the reservoir cap (#14) GM shows it as 1/2” hose.

For either 12 or 14, GM sold it as 25-ft spools cut to length. Any fuel hose from a parts store should be sufficient and a hell of a lot cheaper.

Here’s the part number on the right, but you can probably get what you need from a parts store matching the inner diameter (5/16”).


Thanks part number 12 is what I was looking for, I seem to have a look when I fill the reservoir, thinking that’s the only place it could be coming from! Couldn’t find that diagram no where
