Quick Help please

Just bought this 86 325es 2 days ago and today after work, i got a chance to definitely get in there and check out the engine bay. The previous owner said the motor has been swapped with a 87 325i, (if theres a difference). Well found a couple things today and wanted to see what they were. If anyone can point me to the right direction.

first one is ok, just ignore it as the fuel reg feeds off the other nipple (some only have one)
2nd one is ok just the throttle body heater delete
3rd one the charcoal canister should be connected under side of TB, if the TB nipple is blocked stopping a vacuum leak they might just have just bypassed the canister which isnt uncommon
