Homemade Diesel Injector Pop Tester

In this episode I will show you how I made my homemade diesel injector pop tester. I made it from scrap metal and material that was available in my shop. I use the lathe and mill to fabricate the pump and the fuel line. I hope you will enjoy this video as I enjoyed making it for you. If you have any questions, please feel free to ask me and I will be happy to answer your questions. Thank you for watching and thank you for your support. Be safe and have a great day,

You are a "Jack of all trades" and a master of ALL of them Salam, great video as always!

[@SalamSayhood]

Thank you sir, I appreciate it.

[@joelcary1676]

Thank your for posting videos of what you do. You and I have very similar interests and equipment. It is extremely encouraging to be able to watch you and derive ideas for my projects from what you are working on. I am in the southwest part of Texas.

[@SalamSayhood]

Thank you for watching, I used to go to southwest part of Texas (Mason, Brady, Brownwood, ...etc). Very nice area. I appreciate your comment.

I’m very happy to see the very good video of injector tester you have made , I like to do the some for CAT injectors those have high pressure. Thank very much.

[@SalamSayhood]

Good morning sir, I tested cat injectors for 3304 recently with this tester, I had to make an adapter for them as they are 14 by 1.5 mm thread. Thank you for the comment, be safe and have a great day

Love your accent, just like turning on a Sacha movie 😎 Nice and sophisticated made, quality built!

Good idea 😆

professionnally done equipment. I like it.

[@SalamSayhood]

Thank you, I appreciate your comment

[@SocalMarineUSA]

great stuff. I would add a filter inside the low pressure side just in case something makes it through to the injectors, or maybe an injectormesh screen in the high pressure output - nice video thanks!

[@SalamSayhood]

I thought about doing something like that on the low pressure side. I actually added two coffee filters on the top of the pipe (the diesel reservoir). Thank you for the feedback and the nice comment. Be safe and have a great day.

[@Simon-nz8kt]

sir you are very talented you would make a great teacher.

Thank you sir, I really appreciate your nice comment.

Awesome machining skills, bro. Are you self-taught? Would love a tour of your home shop setup. Subscribed!

[@SalamSayhood]

I learned a lot from my family since my childhood. They had an automotive shop. I also worked on many jobs and learned from that. I self taught too. I will try to tour my shop soon. Thank you for your comment, support and subscription

51:53 a good ideea to make a video on how to build one with of the shelf (no professional tools).

[@SalamSayhood]

Good evening, I may do that in the future, I did explain in detail what to do in case you don't have lathe and mill. Thank you for the feedback

[@lotuslotus718]

Great video. Can electric injector be tested and how would you test it with your pump.

[@SalamSayhood]

Thank you, what type of injectors you would like to test?

[@lotuslotus718]

Thanks for replying. Bosh from Sprinter Mercedes. Thanks.

[@SalamSayhood]

Those injectors are 12 volt. To test, you have to pressure the injector to the specific pressure, it shouldn't leak, when applying 12 volt, the injector should spray good pattern of diesel. Make sure the switch to turn on the injector is far from the spray pattern to eliminate fire.

[@JoseGonzalez-hk2zu]

buenas nochez muy bueno el video... tendras el plano de ese probador de inyectores para que me lo envies por favor

[@SalamSayhood]

Buenos días señor, no tengo. Construí el mío basado en el gato hidráulico que tengo.

[@godfreytlhapane4066]

how do you determine slope when milling the pipe you put reference mark on it?

[@SalamSayhood]

I cut everything square (as close as possible for this project). I didn't mill anything at slope. I explained everything I was doing in the video. If you are referring to why I put a mark, I did so to be able to create two parallel sides to be able to hold the tube in the vise. These cuts didn't have to be precise so I used the reference mark and the square to square the mark to the table for the two cuts, otherwise if the project calls for precise square cuts, I would have chucked the pipe in a square block. Thank you for watching

[@calihumvee1680]

could you make me injector tester just like the one on video and make a cap for the diesel container with it.?

[@SalamSayhood]

I appreciate your interest, however, I am very busy and also I don't sell anything online. You can have a local machine shop in your area build you one. If they don't know how, you can show them my video. Thank you for watching

[@aztecahernandez6539]

A salam malekum Brother. Would you like to sell me this pop tester. I don’t have all the specialty tool to make one and I don’t want to buy a cheap aluminium made of chinisium. Lol. Best Video on pop tester.

[@SalamSayhood]

Good evening, I appreciate your interest and comment. I am not planning to sell it as I will need to use it in the future. Thank you

[@surfreadjumpsleep]

Thank you for publishing this! I'm stuck in Hungary with some diesel injectors that I need to test. Nobody is working except for a machinist. I'm tempted to have one made. How many hours all together did it take you? I also have no idea where to buy a gauge that goes high enough. 240 bar is the trigger pressure for my injectors.

[@SalamSayhood]

It took me about 5 hours to build this tester. I had everything as far as material and tools ready before I started. If I didn't have to record it, it may have taken a little less time. The high pressure gauge (make sure it goes higher than what you need) they are available on eBay, Amazon and other online stores. You can also check out a local hydraulic shop. They may have some used for sale. These gauges are cheap. If you have more questions, please let me know.

[@surfreadjumpsleep]

@@SalamSayhood okay well 5 hours is maybe a little too much time to do this but I'm desperate I might just have someone do it. Couple hundred dollars to get out of here would be great. I'll watch online and see if I can find a more simplified design. I really need to use this just once. Maybe another time later. The ones that they sell online seem reasonable but of course nobody selling them around here

[@SalamSayhood]

You can use the injector pump to build pressure. If you have an extra injector pump and one extra injector fuel line, you can braze a Tee in the middle of the line to add the gauge. You also can get plugs to plug the other outlets (other injector fuel outlets) of the pump so you don't have diesel fuel leaking and you can test the injectors that way.

[@surfreadjumpsleep]

@@SalamSayhood wow this sounds interesting. I don't have an extra pump though. Just the pump that's in the van. I guess the problem is is that the pump requires the engine to be running and the engine is not going to be running without all four injectors, correct? Or can the starter and battery run the pump? Here in Hungary I can hire a machinist... So he could make me caps or adapters to go to another line. So maybe if I use a t adapter on one of the lines? Then I can keep three injectors in and one testing. And then I'll still need a gauge right so that I can see what pressure the pump is pumping at. And it's going to be difficult to do a leak test this way, or? I can use a slow motion camera to capture the video of the gauge of the pump and when it fires. I don't know how fast the gauge is though.

[@SalamSayhood]

What I meant: if you have an extra pump, you can set it on the vise, all the injectors pump gear has bolt to keep the gear on the pump. You can build handle and rotate manually. You have to syphon desiel fuel from a container (higher than the pump) and once no air in the line, you connect to the pump, bleed the pump from air and connect the test line and you should be able to test them that way. Long time ago we did this on an old engine while we were rebuilding it. We connected all the lines and four injectors and we verified the injector had good pattern and no leak. However we didn't test the pressure. If you only testing one injector and plug the others, the pump going to have high pressure and it will be on bypass mode and you still can rotate manually but you may have to have longer wrench. It is easier to have a tester. Let me ask you why do you want to test your injectors? Any smoke or loss of preference? How expensive the injectors comparing to purchase tool or have it made? I made my tool because I have few equipment and the material/tool to make it and the injectors are expensive. They would cost me about $750 to buy new.

What size shock key do you use to open the jack bottle?

[@SalamSayhood]

It was 1-5/8" or one inch and five eighth of an inch.

perhaps I should make a homemade lathe first....
