OK, i've been searching around the web, and found out that my thin nylon vacuum hose is to hard to fit on barbed T fittings, and found 2 possible solutions.
find some Vinyl hose and a compression fitting that will allow me to hook up the newer bigger Vinyl hose to my gauge [ a bitch to find from what i've read]
or
use some 'RTV' stuff on the outside of my vylon vacuum line, then find some Vinyl vacuum hose that has a snug fit. The rtv will seal to the vacuum hose over top and then i can put the lager vacuum hose on the T fitting. guide below

What T fitting should i get that fits the FPS vacuum line? is 3/16ths good?
