I am now running a 4 stage pump which includes an air/
oil separator, this setup requires a vacuum regulator, as the manufacturer mentioned it may make upwards to 19in/hg and I anticipate running about 12in/hg of vacuum.
I have read where I will need a pop off valve incase of a pressure situation, so what I thought was as the vacuum regulator can fit into an O ring thread on my valley cover behind carb, and leave the valve covers clean without any plumbing.
Plumbing the pop off valve from where the mechanical fuel pump used to be on SBF, and if I wanted to use a normal breather for road use just remove the pop off valve, the question maybe is the fuel pump area on the block a good place to take a breather from....
any thoughts.
