Can someone tell me what number 12 is on this picture and if I should replace it when rebuilding the engine... I'm going through getting a parts list together, and want to order everything at one time... Any help is appreciated! thanks

its an oil jet, i always replace it. its 5 dollars, why not?

 

thanks man, i thought thats what it was but I wanted to double check... the money wasnt why i was asking I was asking because I wanted to make sure it was something I should replace or if it was just something that I should leave alone...
