Customer Reviews for VEVOR 400Bar 6000PSI Diesel Fuel Injector Tester Diesel Injector Nozzle Tester with Dual Scale Gauge to Adjust Injector Nozzle Pressure and Testing Diesel Injector Nozzle Pop Pressure Tester

Helaas lekkage langs ventiel, dus alles onder de diesel wanneer je druk wil aflaten. Verder wel optisch degelijk. Retour sturen helaas.

It only halfway works it builds pressure so you can check your spray pattern but it will not hold pressure to check for leak down

Turned up guage didn’t work and leaked diesel when tried to use it.

I am still waiting on delivery. It has not been delivered. Still waiting for my package.

Fonctionne 1 fois sur 10 . pas terrible

Never got the chance to try this product even after ordering twice. Vevor couldn't get it to me. It got lost in their shipping system twice. After days of talking to a computer I finally bought a great one from a different company had it in three days. Then had to wait almost a week for Vevor to finally issue a refund. Bottom line buy somewhere else

Tutto sommato funziona però il fatto che mi dite di non potermi far avere il manometri con scala bar blocca un pò la situazione ... lo avrei comprato da un altra parte

Extremely poor quality, unit failed after 2 minutes of use and started leaking diesel. Pressure gauge is very cheap and not very accurate. The high pressure lines that come with the tester are so badly made that they are unusable and leaks due to the poor mating surfaces. I had to remove an injector line from my truck and use it instead. So unless you're suoer handy and wish to spend time and money modifying and repairing this unit I would pass. This unit is poorly made and does not perform as intended.

I purchased this product based on its advertised durability and sturdy construction; however, I strongly advise against wasting your time or money with this company. Upon receiving the injector tester, my initial optimism quickly turned into disappointment. The device functioned for only two injector tests before it failed entirely. After these initial tests, the gauge ceased to register fuel pressure. To rule out user error, I tested the unit with 12 different injectors, including brand-new ones, all to no avail. I reached out to the company’s customer support for assistance and was provided with a dubious link to an instructional video, which was entirely in Chinese. This video only confirmed my suspicion that the tester was defective. Despite submitting multiple videos demonstrating the malfunction, the company has refused to offer a refund or replacement. Instead, I have been subjected to a frustrating cycle of repetitive responses, such as requests for additional video proof or referrals to the same unhelpful instructional material. I strongly recommend avoiding this company and their products. Opt instead for a reputable brand that stands behind its products and provides reliable customer service in the event of defects.
