I just measured the hard line from the Trico pump and its .25” OD which lines up with your comment. Sorry for all the questions so often but I have made my share of mistakes and am trying my best to limit them going forward. 1/4” hard lines it is. I had Flicken rebuild my wiper pump. And I did locate a machine shop thats will plane the manifolds. Who would of thought of looking into marine shops, but heck we got lots of boats here so i guess it makes sense.
Thank You
