MB part??? No way.
I just used about a 3 inch section of standard vacuum line, the small stuff for a nice tight fit at the hard plastic line. 3 Inches allowed me to get the hard line in pretty far so I wont have to worry about it getting bumped out of position.
Noticed today I could only barely feel the 2nd to 3rd shift and most of the time I could only tell the 3rd to 4th shift by the tach. Very sweet.
