I'm confused. The S-1T has a combined fuel pressure and manifold pressure guage, not a combined fuel pressure/oil pressure gauge unless they came with different instrument packages? If the manifold pressure gauge is starting to fail, its almost certainly because the snubber is gummed up. Its an easy thing to fix. Just unscrew the manifold pressure line from the back and with a philips head screw driver, undo the snubber screw about 1 turn, then turn it back in exactly to where it was before you unscrewed it. This will probably ungum it. The snubber screw is actually right inside the port where the manifold pressure line fitting attaches to the back of the gauge. Its purpose is to damp the oscillations from the engine so you get a smooth reading. Its very easy to set this thing without even running the engine. Just put a small piece of tubing over the elbow fitting that comes out the back of the gauge, then you can suck/blow gently on the tube and watch the guage. You set the snubber so that you get just a bit of delay in the needle movement to your pressure changes on the line.
