Product Description

The AutoMeter 3321 is a Sport-Comp series mechanical oil pressure gauge offering a 0-100 PSI range in a 2-1/16" (52mm) housing. Featuring a race-proven Bourdon tube movement, it delivers accurate, real-time oil pressure readings without requiring any electrical connections - making it compatible with any street or race vehicle regardless of electrical system type. The full-sweep dial, fluorescent red pointer, and white incandescent perimeter lighting ensure clear readability day and night.

The black dial face, white numerals, and silver bezel define the classic Sport-Comp look that has appeared in more winning race vehicles than any other gauge on the market. Installation is straightforward - a 1/8" NPT connection at the engine oil gallery feeds the included nylon line and compression fitting directly to the gauge. A 1/4" NPT adapter is also included for engines with larger oil pressure ports. For performance builds, optional braided stainless line kits are available separately.
