I have a 2001 New Holland LS180 with hole in hard line from control to flex line. Hard line runs between cab and frame. No way threaded nuts will pass though. Anyone know how to replace this line?
Make a bigger hole ... Or use a Swagelok tube fitting after you get the tube in place. I've had very good service with Swagelok fittings in very high pressure gas service. There're other brands but Swagelok has performed the best. (I have no connection with Swagelok, just a customer)
