Review on πŸ”§ YSTOOL Fuel Pressure Tester Gauge Kit for Automotive Engine Injector Pump Testing - 140PSI Gasoline Gas Injection Manometer Tool Set with Schrader Adapter for Auto Car Motorcycle (Blue Case) by Doug Virden

Revainrating 2 out of 5

Wrong size Schrader valve

does not come with the correct Schrader valve bracket for Ford fuel rails. There are a bunch of other useless connectors in the box.

Pros
  • After checking the fuel pressure with the YSTOOL Gasoline Fuel Injection Pressure Tester, compare the reading to the recommended pressure range. If higher, it could be a faulty fuel pressure regulator or a bent, clogged return line. If lower, possible causes include a dirty fuel filter, poor pump performance, improper fuel tank outlet, clogged fuel line, clogged pump inlet filter, or electrical control failure. Gasoline is highly flammable, ask professionals to work away from open flames.
Cons
  • Negative result available.
