Found that link early in my searching.. I refuse to wait for gear oil to creep down 2 2.5 feet of fuel line. I plan on using the FUMOTO valve to cleanly drain (HOT!!!) oil out and cleanly fill new oil back in.
I haven't been under the Sport to look, did ford give us a fill port in the old location? if they did, Ill just swap out the fluid like I did on my SHO, and while I have the drain plug out, measure the threads. Would be just like an engineer to give us a drain plug but take away the fill plug!!!
