Yea, I retained the original lubrication fittings and even the rope seal - just had the lipped seal as belt and braces. I don’t tighten the gland nut much so would probably leak in it’s own but holds some lubricant and helps the lip seal.
I thought modern car pumps have a lip seal - perhaps modern coolant has some additives to help with lubricant? The small shaft size on the dodge probably doesn’t help.
cheers,
