Should the H tube have a restricted diameter in one of the tube?
While we are at it. Is there any preference between the H tube and the more elaborate bypass tube system with the compression fitting and longer steel tubes. I assume that the H tube was fitted to later cars as a cheaper alternative. This is correct.
Are the two types interchangeable.
Thanks
As Steve has said, they are interchangeable.
Back in the 90s, Sprintspares sold the H-piece c/w hoses as an upgrade for the later cars,
said later Sprints having the extended pipe work as standard.
If I had to choose one, I would go H piece (Chris Witor sells remade versions in stainless steel).
It is simpler.
However, I have went a different way by going for the heater input taken of the back of the cylinder
head…
