I'm using the stock primary fuel rail and injectors on my 20B, and a TWM

series connection from the secondary rail.  It seems easiest to just cut

it

off and put on the fitting.  Is there a good reason to keep the dampener

on

there?

Thanks.

Al, I have a friend in CA who has his own shop repairing Mazda Rotary
engines for over 20 years.  He says to ditch the fuel rail pulse dampener as
it is only a matter of time (not if) before the pulser develops a fuel leak
due to fatiguing of the dampener disk.  FWIW
