The hose just disappears down behind the false firewall. To change that hose looks like I have to remove that firewall to access the fill tube? It has been so long since I did a clutch m/c I can not remember.Clutch master under dash.
I don't think you are talking about the clutch master cylinder fluid supply hose which attaches to the brake fluid reservoir and goes through a hole in real steel firewall and attaches to clutch master cylinder under the dash. There is not steel line that hose attaches to either.The clutch reservoir hose goes to the front of the false firewall - no need to remove that. The hose is a bout a foot long until it reaches the steel pipe that runs behind the engine, in front of the false fire wall, near the rule lines.
