Fuel Injector Testers & Cleaners

Precision fuel injector tester and cleaner, built to bench-test, flow-test, and ultrasonically clean injectors the same way a professional injector rebuild shop does. If you're ready to move beyond guesswork and verify exactly how an injector performs before it goes back into a customer's engine, this is where to start.

Why a Real Fuel Injector Tester and Cleaner Matters**

Cleaning an injector without testing it afterward tells you it's clean — not that it works. A proper fuel injector tester and cleaner checks resistance, flow rate, spray pattern, and leak-down under real operating pressure, so you know an injector is airtight and metering correctly before it ever goes back on an engine. Skipping that step is how a "cleaned" injector ends up causing a misfire, a rough idle, or a comeback repair a week later.

Our flagship machine, the PROCHARGE M-5000, is a hand-built, American-made fuel injector tester and cleaner engineered from marine-grade aluminum and CNC-machined components, built to hold high-flow injectors like the Bosch 210 at full pressure across high RPM ranges without losing accuracy. It pairs a built-in ohm meter for fast resistance checks with a high-volume WALBRO/FUELAB fuel pump for real flow and leak testing, plus dedicated ultrasonic cleaning solutions to get injectors properly clean before they're tested.

**What to look for in a fuel injector tester and cleaner:**

- Fuel delivery strong enough to stress-test high-flow and low-impedance injectors at real operating pressure, not just a light bench check
- A built-in resistance/ohm test so you can catch a bad coil before you even flow the injector
- Solid, corrosion-resistant construction if the machine will see marine or high-humidity shop environments
- Ultrasonic cleaning capability, not just a flush, to actually remove varnish and debris from the injector body
- Manufacturer support and a real warranty behind the machine.

**Compatibility note:** PROCHARGE testers are built around common OEM injector platforms including Bosch, HPDI, and Optimax — check the specific machine's spec sheet for adapter compatibility with your injector lineup before ordering.
