Connecting small vacuum hoses together?

[Zenja]

I'm trying to install the boost gauge part of my TT but the hose that comes out of it is really small and narrow. Using a t-fitting doesn't seem like it would work too well because there's not a lot of I.D.

How would I extend this little vacuum hose far enough to connect to a vacuum source? Super glue seems like the only thing that might work

They make fittings that have a small side and a big side so you can have the small hose going in and a bigger hose coming out if you need too.
