Default yep...you can...I broke one when installing my VDO mechaincal boost gauge....

are you talking about the thing that tightens down to hold the boost/vacuum line into the gauge?
I found it (or something very similar) at Home depot...I believe in the brass fitting aisle

Default well, sort of, what I did was get a coupler that fit the boost line...

the really small one going from the FPR line (that you tapped with the T thing to get the boost info) to the boost gauge...anyway, what came with your boost gauge was probably something that connected that line to your gauge...Home Depot did not have that exact thing, so what I got was a couple that connected that line to little bigger hose (which I got at Pep Boys autopart store) - I then connected that little bigger hose to the boost gauge...it's tight and I'm reading boost and vacuum correctly so I guess it works. Just bring the gauge with the line the the store and try things out - that's what I did. You are really only needing something that will take boost pressure and connect it to the gauge without leaks...it really does not matter what size all these lines are once they are connected because it is a closed system and you are only looking to see pressure changes.
