Vacuum Tank Plumbing

Unknown

Hi Gang,



Can anyone advise me as to the correct fittings and arrangement for

the vacuum tank plumbing?



An educated guess leads me to this:



A 1/8" pipe branch tee on the vacuum fitting at the top of the

vacuum tank, with a hose barb (for wiper) on one end, and a 5/16

flare to 1/8 pipe adapter on the other (to go to the intake

manifold).



Then 5/16" OD copper tubing from there to the intake manifold, where

the line terminates in a 90 degree 5/16" flare to 1/8" pipe adapter

on top of the manifold.



The fuel outlet petcock on bottom of the tank is a compression

fitting, so I suspect 5/16" copper line to the carburetor, with a

compression sleeve and long nut at the petcock. On the carburetor

end, I am using a short piece of rubber hose and a hose barb on the

carburetor to avoid stress on the float bowl.



As for the fuel inlet, I have 5/16" copper line coming up from the

steering box area, around the outside of the firewall to the inlet

on the tank, with another 90 degree 5/16" flare to 1/8" pipe adapter

at the tank inlet.



All of the flare and compression nuts are long nuts.



I know all of this will work, but is it correct? If not, what is?



Best Regards
