Accidentally dropped engine oil bottle's cap in my diesel tank

Little bit curious how you managed that. But no. The only thing I could see being a problem is if it gets stuck up against the pickup tube. But I highly doubt that, it's either floating or sank to the bottom so you'll be fine.

 

Sounds alcohol related? You need to get it out but I would not turn down a load because of it. Look for it every time you stop and grab it. May have to make a fishing tool with that KW.

 

May I suggest a minnow net ? Lol

 

Seriously I wouldn't worry about it , I dropped a shop rag in my fuel tank once and its still there as far as I know .

 

Let it ride!!!! Only way I could see to get it out would be to drain the tank, remove the straps, and roll it upside down till the cap falls back out the fill. Don't think it would hurt much, just wait till you have to replace the straps and remove it then.

 

Think of it this way Garry it's not gonna get to the fuel filters lol
