Q 2. What is the main purpose of the 33100400 common rail cap set?

A. It is a set of caps that, used with the Universal Digital Pressure Tester, closes common rail injector inlets to diagnose leaking injectors.

Q 3. How does the 33100400 cap set work with the 33100100 and 33100000 kits?

A. When combined with the pressure tester, the caps allow individual injector inlets to be blocked so pressure changes reveal which injector leaks.

A. It can be used on three-, four-, five- and six-cylinder engines with compatible common rail fuel systems.

Q 5. What plug sizes are included in the 33100400 set?

A. The set includes six M12 x 1.50 plugs and six M14 x 1.50 plugs, covering common rail rail-inlet thread sizes.

Q 6. Why is a common rail injector leak test kit important?

A. It lets technicians pinpoint leaking injectors quickly without removal, supporting accurate diesel diagnostics and reducing guesswork.

Q 7. In which workshop category is this cap set listed?

A. It is listed under electrical repairs and diesel diagnostic tools, associated with the universal digital pressure tester.

Q 8. How should the caps be used safely on high-pressure fuel rails?

A. Always depressurise the system before fitting caps, tighten them carefully and follow the tester instructions to re‑pressurise.

Q 9. How should the cap set be stored to avoid losing small components?

A. Keep it in a dedicated compartment within the pressure tester kit case, clearly labelled by plug size.

Q 10. Why is using correctly threaded caps essential for common rail testing?

A. Correct threads ensure secure sealing and prevent damage to the rail’s internal threads or leaks under test pressure.

Q 11. What SEO search terms accurately describe this product?

A. Terms like “common rail injector leak tester caps”, “M12 M14 common rail cap set” and “Sykes Pickavant 33100400 kit” are highly relevant."
