@DakotaTravler thanks so much for this tip. I was initially dubious about being able to get this hose replaced without pulling the manifold but it really was not too bad. Pushed off the old one with a screwdriver. I then staged the new spring clamp using one of the "holders" from another hose to keep it fully expanded. I used two loops of p-cord as in your photo. After getting the hose seated, pull on the "tail" to remove the p-cord. Then yank upward to remove the spring clamp holder. Done.

 

Good to hear! It may be a tricky procedure, but I do feel that is it much better than taking the intake off. Which would of course ideally involve all new gaskets too. This method, with patience, saves a lot of time and money.
