Thanks for the input guys
juld0zer, I think you are right, might as well just replace the whole lot while it is all opened up. was just thinking of drilling it out because I am lazy to measure the hose and have it made up etc.. haha it would be great if you can find the thread specs
DOOMMONKEY777, yeah although it has been flushed a few times, I think it would not hurt to do another flush.. replacing the lines will force me to flush it anyway so I think it is a double whammy haha
