GearWrench KDT-3289 Oil Pressure Check Kit, 10-Piece is the diagnostic tool for testing engine oil pressure at the oil filter port on most passenger cars and light trucks. At today's online price of $67.15 versus a $149 compare-at price, this is the affordable deal to buy and save 55%.
Remove the oil filter or sensor, select the matching adapter, connect the gauge hose, and run the engine to read pressure on the 0–100 PSI calibrated gauge. Compare readings against your manufacturer's specification to diagnose oil pump, bearing, or relief valve problems.
Five adapters cover both domestic and imported engines, threading into common oil filter ports and pressure sender locations. Match your filter base thread to the included adapter sizes; the guide on each adapter is stamped for quick identification.
If the gauge reads zero, check that the adapter is fully seated and sealed at the filter port, verify the hose couplings are tight, and confirm the engine is at operating temperature for an accurate reading.

Tested oil pressure on my Silverado at the oil filter port and the adapter sealed perfectly. Gauge read a steady 42 PSI hot which matched spec. The hose feels well made and the case keeps everything tidy. Great diagnostic value for the price.
All five adapters covered every car I needed to test. Gauge is easy to read. Wish the hose were a little longer but no complaints otherwise.
Quality kit, accurate readings, fast shipping.
The gauge seems reasonably accurate based on comparing with another tester. Fittings are a bit fiddly to thread in and one adapter felt slightly loose until I used some thread tape. Fine for a home mechanic checking a few vehicles a year.
Just finished an engine swap on my son's Civic and wanted hard numbers before buttoning it all up. This kit threaded right into the oil pressure port and showed a healthy 60 PSI cold, settling to proper hot pressure. The 0-100 PSI gauge has a clear white face that's easy to read in the engine bay. Adapters seem machined well with no leaks. For $67 this is a proper diagnostic tool, not a toy.
Bought it to diagnose a low pressure warning on my wife's minivan. Turned out the sender was bad, not the pump — this kit told me that in ten minutes and saved a very expensive wrong repair. Gaskets and adapters all sealed up properly. Recommended.
