Boost Gauges Don't Work

[BRAD_PADGETT]

I have an 85GN with the band dash boost gauge as well as a VDO boost gauge which is teed in off the fuel pressure regulator. Both gauges worked fine. I started the car today and both boost gauges do not work but the turbo is making boost. Any ideas? Thanks- Brad

ut oh! did you follow the hose from the VDO guage to the intake where it is connected to make sure there is no disconnection, or hole? The stock guage almost never works on our cars...never know why, but they just suck. If you dont find any holes, or the pipe is connected, remove the guage and check the compression fitting in the back. If all else fails, refer to the holy bible of the TR community, Gnttype.org. I know there are some articles for the boost guages on that site!!! good luck!
