Extracting creosote oil from coke oven?

Alright, so I've been exploring the various mods in the pack for producing materials and energy, but in the mean time while gathering materials I decided to use coal coke as my major source of power. Unfortunately, despite how I try to extract the creosote oil from the oven, nothing is working. Extraction pipes from buildcraft, fluiducts, nothing is getting the oil out of the oven, the only option is to manually extract using a bucket. I remember these working back in the FTB modpack, is there something I'm missing?
