Should I replace the o-rings on the injectors or just leave em? they look ok, but then again, ima tard. And if they DO need replaced, can you get them at liek advanced auto or some place like that? or do i need to order em special?

 

you should be able to order them from advance or napa. i reused mine, put some vaseline or grease on them, get them moist, it might help condition them a little bit

 

Yeah you can reuse them. I just threw some oil on them to lubricate them.
