Bought this overseas-made tester to troubleshoot a fuel problem with my 1996 Impala SS. The gage fits fine, though you will need pliers to tighten it enough to stop leaks. The drain valve is a handy feature, but the clear fuel line will harden after the first use, making it aggravating to use. The schrader valve connection has a rubber gasket inside that will deteriorate after a couple uses, causing the connection to leak and make the gage useless. This is a proprietary rubber seal, and local auto parts will not carry parts for these cheap gages. I have tried an o ring without success. Recommend investing in a better quality gage unless you plan to use it once and throw it away.
