Compatible with most engine applications using the included adapters, this vacuum and pressure gauge kit identifies internal engine issues such as worn rings, valves, and leaking head gaskets. The 3-1/2" (88.9 mm) gauge provides dual-scale readings from 0 to 30" (0 to 76.2 cm) Hg vacuum and 0 to 15 PSI to test low-pressure fuel systems and pinpoint cracked lines. For protection during use, the gauge is housed in a chrome bezel with a protective outer boot.
