Draper Expert Vacuum and Pressure Test Kit (22 Piece)

One Kit. Dozens of Diagnostic Applications.

The ability to apply, hold and measure vacuum or pressure is fundamental to a huge range of vehicle diagnostic and servicing tasks — from bleeding brake circuits and testing fuel system integrity to checking turbo wastegate operation and diagnosing emissions faults. Typically these jobs would require multiple dedicated tools. The Draper Expert CTEVG4-E brings them all together in a single, comprehensive 22-piece kit.

Compatible with most vehicles and backed by Draper Expert build quality, this is the kind of multi-application tool that earns a permanent place in a professional workshop — not because it's a compromise, but because it genuinely handles the full breadth of tasks it promises.

Dual-Reading Vacuum and Pressure Gauge

At the heart of the kit is a 63mm dual-reading gauge calibrated from 0–60psi and 0–1bar, covering both vacuum and pressure measurement in a single instrument. The large 63mm face provides clear, readable results across the full range, and the dual psi/bar scale means you can work directly against whichever unit your vehicle service data specifies without manual conversion.

The gauge and pump are integrated into a single hand-operated unit that generates both vacuum and pressure on demand — giving you complete control over the test conditions without needing a separate compressed air supply for pressure applications within this range.

Brake and Clutch Bleeding — Fully Equipped

One of the most commonly used functions of the kit is one-person brake and clutch fluid bleeding. The three dedicated bleed nipple adaptors connect directly to the brake or clutch caliper bleed nipples found across the widest range of vehicle makes and models, while the two 120ml fluid reservoirs capture expelled fluid cleanly and safely. The ability to bleed brakes single-handed — without a second person pumping the pedal — is one of the most practical time-savers in workshop use, making this aspect of the kit alone worth considerable value to any busy independent garage or mobile mechanic.

Turbo Wastegate and Boost System Testing

Turbocharger faults are among the most frequently misdiagnosed issues on modern petrol and diesel vehicles, often resulting in unnecessary and expensive turbo replacements when the actual fault lies with the wastegate actuator, boost control solenoid or associated vacuum lines. The CTEVG4-E allows you to apply and hold measured vacuum or pressure directly to the wastegate actuator and associated components, confirming whether they are holding correctly or leaking — providing clear, evidence-based diagnosis before any major components are removed or replaced.

Fuel System Fault Finding

Fuel delivery problems — including leaking fuel pressure regulators, failing diaphragms and vacuum-operated fuel system components — can be quickly and accurately assessed using vacuum and pressure testing. The kit's combination of hose cones, extension tubes and tapered adaptors allows connection to a wide range of fuel system components across different vehicle architectures, making systematic fuel system diagnosis straightforward and reliable.

Air Conditioning, Emissions and Ignition Testing

Vacuum testing is an important diagnostic technique across several other key vehicle systems. Vacuum leaks in air conditioning systems, EGR valves, idle control systems and emissions components can all be identified by applying a measured vacuum and checking whether it holds. The CTEVG4-E provides the controlled vacuum source and the range of adaptors needed to test these systems methodically, reducing diagnostic time and avoiding the guesswork of symptom-based fault finding.

Valve Stem Oil Seal Testing

Worn valve stem oil seals are a common cause of blue smoke on startup, high oil consumption and fouled spark plugs — but they can be time-consuming and expensive to replace unnecessarily. Vacuum testing allows suspected valve stem oil seals to be tested before committing to a valve stem seal replacement, providing a more confident basis for the repair decision.

Easily Dismantled for Cleaning

Vacuum and pressure test equipment inevitably comes into contact with brake fluid, fuel, oil and other vehicle fluids. The CTEVG4-E is designed to be easily dismantled for thorough cleaning between applications — an important practical consideration for a kit used across fluid systems, where cross-contamination between brake fluid and fuel system components, for example, must be avoided. Easy disassembly means the kit can be properly cleaned and maintained, preserving both its accuracy and its service life.

Comprehensive 22-Piece Contents

The full kit includes everything needed to cover its broad range of applications straight from the case:

• 1 x 63mm gauge and pump
• 1 x 32mm suction cup
• 1 x Tapered hose adaptor
• 1 x Gun cone
• 2 x 120ml fluid reservoirs
• 3 x Bleed nipple adaptors
• 5 x Extension tubes
• 8 x Hose end cones

The eight hose end cones and five extension tubes provide the connection versatility needed to reach and seal against a wide variety of ports, valves and nipples across different vehicle systems and architectures — from small vacuum ports on emissions components to larger hose connections on brake master cylinders and fuel pressure regulators.

Supplied in a Plastic Storage Case

All 22 components are supplied in a fitted plastic storage case that keeps every cone, tube, adaptor and reservoir organised and immediately accessible. With this many small components, a well-organised case isn't just a convenience — it's essential for ensuring the right fitting is always to hand and that nothing is lost between jobs.

Who Is It For?

The Draper Expert CTEVG4-E is an essential addition to any professional workshop, independent garage or mobile mechanic's toolkit. Its breadth of application makes it particularly valuable for general repair workshops handling a wide variety of vehicle types and faults — where the ability to systematically test vacuum and pressure across multiple vehicle systems from a single kit saves both time and the cost of multiple dedicated tools. Experienced DIY mechanics tackling brake bleeding, turbo diagnosis or fuel system fault finding at home will also find it a highly capable and versatile investment.

Q: What vehicle systems can the CTEVG4-E test? The kit covers a broad range of vehicle systems including brake and clutch circuits (bleeding and pressure testing), turbocharger wastegate actuators, fuel system components, air conditioning vacuum circuits, transmission vacuum systems, valve stem oil seals, ignition vacuum advance systems and emissions components such as EGR valves. It is compatible with most cars, motorcycles and light commercial vehicles.

Q: Can I bleed brakes single-handed with this kit? Yes. The kit includes three bleed nipple adaptors and two 120ml fluid reservoirs specifically for one-person brake and clutch bleeding. The vacuum pump draws fluid through the bleed nipple and into the reservoir without requiring a second person to depress the brake or clutch pedal, making it one of the most practical aspects of the kit for both workshop and home use.

Q: Do I need a compressed air supply to use this kit? No. The gauge and pump are integrated into a single hand-operated unit that generates both vacuum and pressure manually. This makes the kit entirely self-contained and usable anywhere — on the driveway, at the roadside or in a workshop without a compressor — for all applications within the 0–60psi/1bar range.

Q: How does vacuum testing help diagnose turbo faults? Many apparent turbocharger failures are actually caused by faults in the wastegate actuator or boost control vacuum circuit rather than the turbo itself. By applying a controlled vacuum or pressure directly to the wastegate actuator and checking whether it holds, you can confirm whether the actuator is functioning and sealing correctly — or whether it is leaking and causing boost control issues — before committing to a turbo replacement.

Q: Why is the easily dismantled design important? The kit is used across multiple fluid systems — brake fluid, fuel, oil and others — that must not be cross-contaminated. Easy disassembly allows thorough cleaning of hoses, cones and reservoirs between applications, maintaining both the accuracy of the tool and safe working practice across different vehicle systems.

Q: What does the suction cup do? The 32mm suction cup allows the vacuum pump to be used to test the vacuum integrity of flat or smooth-surfaced components — such as brake servo check valves, vacuum-operated actuators with flat ports, or certain emissions control components — where a hose cone connection is not suitable.
