yeah, same as 606, however you could end up with blocked pipes from the tank running under the car.
i had this (with the fuel strainer) - think it was solid fats that had gradually built up, blocking the pipe. I Had to disconnect both ends, and used a bicycle pump to blow air through it to unblock it. something flew out the end, wish i had put a bag around it to catch the debris to inspect but didnt.
this was a few years back now, no problems recently. Probably all due to quality of the WVO.... in the early days i used filter socks which arnt as good as filtering via cartridge filters.
