I have a Summit aluminum vacuum reserve tank and gauge used for power brakes when you have a big choppy camshaft that does not make a lot of vacuum. The tank is new in the box and the tank part# is G1460 and the gauge is G3124. I paid $85 a few years back but I will sell it for $65 with free shipping to the 48 states USA only. Send me a PM for a photo. Located in Battle Ground WA.
