Dont want to run smoke coming out of oil filler cap

[Mutant Pony]

Oh alright thank you. Is there a way that the charcoal canister could be casing the truck to run the way it is running cause when i bought the truck i got another one of those cause the first one broke and ran great for bout four months.

No, You can try unhooking it for piece of mind though. It will run fine with it unhooked.(if there is nothing else wrong).
I highly suggest a fuel pressure test. It should be around 35psi.
