How To Clean Your Fuel Injectors - No Expensive Tools Needed

So as a follow up from my last video on how to test fuel injectors, here is a video on how to clean fuel injectors yourself. Whether you want to clean clogged up injectors or simply clean an injector from a wrecking yard before you put it in your engine, this quick and easy method will save you both time and money. Clogged or dirty fuel injectors could cause a missfire, poor engine performance, a lean condition and other issues that should be addressed sooner than later.

Here are links to some related video's.

your video saved me from replacing all my injectors. found 2 bad, 1 wouldn't fire the other cleaned and worked great. thank you! saved me $$$$.

instead of making a hose reducer plug the other end of that hose with a bolt and a hose clamp on it. drill a tiny hole in the side of the hose just big enough for the spray cans nozzle. done.

Dude, the way you adapted the hose down to the carb cleaner straw to clean that injector was sheer genius! Never saw a better way of cleaning a injector before! Brilliant! I never had any faith in cleaning injectors or luck, but I will be revisiting that, after watching this vid! Simply Awesome! One thing I would recommend for your not so experienced viewers, is to use a heat gun to shrink the heat shrink and to make sure that there battery is a good distance, from the injectors to prevent accidental ignition of any fuel or carb cleaner. Other than that, once again SHEER GENIUS !

Thanks for this great video. I’m chasing a P300 and this helped me exclude the fuel injectors. FYI everyone, don’t use clear plastic tubing at the end where the injector is inserted, it will blow off the line. You gotta use real fuel line and a hose clamp.

I used silicone self-seal tape on the red straw hose. A little vise outside and perfect. I also rebuilt each injector. 20$ parts. Kinda fun and nicely done. I watch your work thanks

I've seen a method like this before but, thank you very much for taking the time to get the close up shots during cleaning. You could actually see the pattern change from a divided stream to more of a mist. Very cool.

Honestly, some of the best videos on Youtube for auto work.

Nice vid, try a 9V smoke alarm battery, most injectors will open with one without the risk of burning the solenoid.

Good idea👍you could eliminate almost all of the tubing by using a brass fitting into the first large hose that was clamped onto the injector, and reducing it to the final size..i.e. using a plug and drilling a hole in it...

[zeke]

Wouldn't it be better to back flush it first then run it through the injector? Just my thought it could get anything lodged in there out first thought the larger side rather than trying to push it through the injector

I just wanted to comment and give you a big thank you. 3 F-ing days of trying to figure out why i kept getting a misfire on cyclinder 3. My friend that traded me the scion tc I have said there is a lot of oil in one of the wells so he though it was the valve cover. Well I found out there was oil in every port...nice. I did an oil change, spark plug change, valve cover gasket change (which was bad), and checked all coil packs...and still the misfire. I don't have the money for injectors but i wanted to test it to be sure. I watched your trick and tweaked it. I simply taped the small red tube on to the injector port with electric tape. I made sure to back the tube off so as not to disturb the cylinoid. After checking port 3's injector with this trick, my problem was found. Ahhh, it feels so damn nice to have that piece of mind. Thanks again bud.

I made the same tubes you did and got the same shrink tube kit at harbor freight, worked awesome!! Trying to fix a cylinder 5 misfire code. Now I just need to get the rest of my parts and hopefully no more misfire. Thanks for posting the video

[chancevilardo]

Just Wrap the tube in duct tape til it fits in the hole😂

[Mark_Nadams]

Good Ideas - BUT - You should not use the marine heat shrink tubing with adhesive inside. There is a possibility if the adhesive is exposed to the cleaner used, the adhesive could dissolve and get into your injector. You are better off to use the plain heat shrink or just use clamps.

video. Saved me about $400 just by not having to replace the injectors. Thanks for your time. Knowledge IS power.

There are numerous problems one must check when cleaning injectors manually.

Leaking. Fuel injectors have individual components – pintles, balls and discs that must be properly sealed while under operating pressure to avoid leaking.
Fuel volume. Injectors need to supply the right amount of fuel under operating pressure.
Atomization. Fuel needs to be under high pressure and atomized properly to provide optimal combustion.
Distribution. The spray pattern of the fuel mixture is extremely important to guarantee safe and efficient combustion.

I like the speed of the video and that you didn't talk too much. I will subscribe. Thank you for posting this. With the COVID-19 stuff my mechanic has health issues so I'm doing more work myself. Saving $ but also super nervous.

[orangev]

A good video but instead of all them tubes & shrink wrap just plug one end of large tube (the one that goes on the injector) with a bolt or cork or something and a clip over it then for the spray straw punch a small hole with a sharp spike like a small nail push the straw in & glue it in place. then you have a more compact & cheaper device

[billydamnit]

I'm definitely buying new injectors

[shamothecow]

That was way more work then it needed to be
