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

Works as described. Checked old injectors and tested after rebuild. Very heavy build. Only improvement would be more robust adapter tubes. Had to be really careful when tightening adapter connections. Recommend using a backing wrench on injector body to keep from stressing tube.

This tester saved my bacon ! I tested my brand new injectors and one of them was popping 650 psi to high and another was popping 400 psi to high. I was able to remove shims to adjust them. Definitely worth the money. Build quality is great for occasional use.

works great, use the O rings with the pipes/adaptors; otherwise it will leak.

Wow... more than disappointed. I wish I could use curse words here but I will say what I can. I did not want to believe some reviews but waited for shipping. Showed up with broken gauge, stuck at 1000psi no matter what. Gauge visually destroyed, inverted. Hard to explain. Overseas junk but no other choice but to make them eat the shipping cost and order again. Problem is i imagine they just box it back up and reship. As well as this is an item i imagine a lot of people return after use and they send back out. Hopefully get a good one. Won't find anything in this price range worth a f, but for an emergency gotta have it.

It's hard to beat the price on this item, but...sadly it seems most folks that buy them have to "rework", "modify", or "repair" them right out of the box. Mine was no different, at least the reservoir arrived intact. Unfortunately, one of the injector adapter pipes was swaged together with an extra...yes, 3 total ferrules. this makes one of the hex flare nuts unusable. Its also unfortunately the adapter tube that i need for my injectors. I could send it back, but based on the reviews, i might end up with another one with a broken reservoir. I'll keep it, and just cut the extra ferrule off with my dremel.Other issues: description in the ad says body is cast iron, and right next to that, it also says aluminum. The one i got is definitely cast iron. The brand says Mophorn, but huge sticker on the back of the gauge says Vevor...go figure..Update: Make sure you flush this unit before use. Mine was filthy inside. I ended up disassembling it completely to clean all the flow paths. Last thing you want is to pump a bunch of dirt into new injector nozzles. It took a bit of tweaking to get it re-sealed, but it seems to work OK. Still only 3 stars though. You shouldn't have to put this much effort into a brand new tool.

ok

Unit leaks from everywhere, tried to reseal and tighten to no avail, gauge only works when bypass valve is open therefore defeating the purpose of the tester, almost like it was assembled backwards as far as the bypass and outlet to injector goes. 2 stars because it sort of functions for a quick and dirty 'does it pop at all' and spray pattern check with no pressures to record. The injector line adapters work well.Poor build qualityPoor quality controlRequires reengineering to functionSlightly better than building from scratch

Built like a tank and works like a charm.Great value for the money.(Would have given it 5 stars, but the instructionswere a bad and barely readable photocopy.)
