im fitting a bailey dump valve to my let'd nova which is fine but i have been ive just been told how to blank off the original dv and i just wanna make sure its right
to me it sounds bodged but ive been told to cut the vacuum pipe goin to the original dv and blank off both ends.
is this right?
ive also heard you can put a washer or something in there to stop it also.
if so how is this done and what size washer do i need(thickness and roundness)
im a little stuck
any help would be great
