7.3l Compression Guage Kit
Product Description
This is the correct glow plug adaptor and compression gauge to measure the compression in your 7.3 PSD's. The gauge has a pressure release valve to hold peak compression readings. The adaptor uses a quick connect fitting to connect to the gauge hose. Leak down tests are also possible. Adaptors for other engines coming soon.
**This kit works for all 7.3l Powerstrokes**
