I got a dezod vac block and these fittings r wayyyy bigger than the fittings on my boost gauge and bov....some one care to explain how I'm supposed to connect these...if I get a line that fits the block it's wayyyy to big for the bov and boost gauge.....

 

u need to buy those plastic tees at autozone it will change size of the vac lines

 

didnt your boost gauge/bov comes with that adapter that allows you to use bigger hose? if not some plastic Ts should do.. or you can buy new fittings with a smaller barb

 

We supply some 1/4" fittings and some 5/32" fittings. The 1/4" fittings are for connecting to a larger vacuum line, the 5/32" fittings are for connecting to most accessories such as a boost gauge. Use the smaller ones The ports you decide to now use plug up with the supplied 1/8" NPT plugs. It's pretty simple. If you are using a boost gauge that has a nylon line that is 1/16" then you won't be able to hook up directly to the vacuum barb as that is vacuum hose only.
