A man was driving through Wyoming one spring evening. The road was deserted and he had not seen a soul for what seemed like hours. Suddenly his Cummins ISB started to cough and splutter and the engine died, like right now. It just left him sitting by the road in total silence.
He jumped out and popped the hood. Nothing there made any sense, nothing that he could do to get it going again.
Being a Newbie, he had a limited knowledge of diesel engines, so all he could do was look at the engine, feeling despondent wishing he had listened to them guys on TDR. Spares they told him. 
As he peered by the gradually fading light of his flashlight, he cursed that he had not put in new batteries, like he had promised.
Suddenly, through the inky shadows, came a deep voice, "It's your Lift Pump!"
The man jumped up quickly, striking his head on the underside of the hood. "Who said that?" he demanded :-{} angrily rubbing his head.
There were two horses standing in the field alongside and the man was amazed when the nearest of the two horses repeated, "It's your Lift Pump, tap it with your flashlight, and try it again. "
Confused, the man tapped the Lift Pump with his flashlight, turned the key and sure enough, the engine roared into life. Oo. He muttered a short thanks to the horse and screeched away.
When he reached the next town, he ran into the local bar. "Large whiskey, please!" he said.
A rancher sitting at the bar looked at the man's ashen face and asked, "What's wrong? You look like you've seen a ghost!"
"It's unbelievable," the man said and recalled the whole tale to the rancher.
The rancher took a sip of his beer and looked thoughtful. "A horse, you say? Was it by any chance a white horse?"
The man replied to the affirmative. "Yes it was! Am I crazy?"
"No, you ain't crazy. In fact, you're lucky," said the rancher, "because the black horse don't know crap about diesels!" :-laf :-laf
