2003 Q-Cab 4.7 4x4

Does anyone know the size of the fitting for the high pressure hose connector where it goes into the rack and pinion? Mine is leaking, I think it may be just an o-ring but not 100% sure. The fitting is pretty rusted up so I don’t know if I can get it out or not. I picked a new one up just in case and it is an 18mm. I don’t have any of the open end flare nut wrenches and wanted to pick one up. I believe it will be my best shot of breaking the old one loose without rounding it off. Once I get it removed I’ll make a decision on just replacing the o-ring or the entire hose. I could use the $40 I spent on the new hose towards the ac compressor that’s raising cane and needs replacing before the hot weather gets here.

Thanks,
Griff

 

yes. Large side is 18mm flanged O-ring and the small side is 16mm flanged O-ring.
