Hi there,

I'm replacing my M.A.P sensor vaccum hose.
My question is "Do the hose have to be the same size as the original?

Exactly the same no
but using bigger, that may cause a leak is no good and very small may cause a restriction
so if its within reason and no leaks it should be OK
check vacuum source in the manifold if restricted
