Where does the boost gauge line tie into the super charger? Are there any diagrams that I can follow?

 

The short answer is look under the dash, find the line that goes to the stock gauge. Put a T in there and run the line to your new one. There is probably a how-to some where on here if you search.

 

What if your doing a swap and there isn't a factory gauge? Where does it go hooked up?

Thanks

 

Any vacuum/boost line connected to the intake manifold / plenum past the blower..

 

under the blower or after the blower

 

It MUST be after the blower, probably by the blow off valve. (Drivers side, rear of blower)

(I think it’s controlled by vacuum / boost line, unsure. It is mechanically actuated but pneumatically controlled.)

Best bet is to select a vacuum line “plug you’re gauge” and see what happens, oh be sure to plug the other side of the hose connection..

I know of two lines that run on the driver’s side, two distinct sizes, (¼” and 3/8” I don’t remember! One of these might work)


If it‘s hooked up before the blower, it will only show vacuum, but not boost!
