This truck came in for a diag of inop fuel gauge and intermittent rough idle, stumble.
Are we surprised the sending unit failed? Here is why we PREACH maintenance, fuel additives, and every other advice I give out. Use it. This looks expensive.
This fuel system will need a thorough cleaning and who knows what else we find. Rest assured this Duramax will leave healthy and ready to scoot! 🦾
