Gen1/2 injector removal (tool)

[1TONY1]

As time goes on I had noticed more and more Viper injectors being slightly damaged or really scratched up from removal when they were sent to me for cleaning. As I have said before, it's easy ...... well, I got my butt kicked a few days back when using the high tech procedure from the service manual
This particular intake had been off the car for around four to five years from a supercharger install and these injectors did not want to come out . I could have done it with the pry method but each injector would sustain quite a bit of damage.

Here is what I came up with:
First: How to "grab" the injector ?? There is a small hole on each side toward the top that look like they were there maybe to put some kind of retaining pin in the middle of the injector. These holes are fairly deep and looked to be a good prospect.
Second: Looking through the shop I found a pair of good size pliers that I found rusted up somewhere....probably under some old house I was remodeling. I started cutting on them with the band saw then the air cut off tool to get the sizing in the ballpark and then finished up with a small cutting wheel on the Dremel and then a hand file.

The results were great. Grab each injector and twist side to loosen to loosen. Then position the injector where the pliers fit square against the intake. At this position when prying it is almost a straight up pull. Each one took about five seconds.

This took me about thirty minutes to get right. This tool will certainly be on loan for folks doing business with me and other VCA members will be welcome to it also if you are a trusted VCA member.
Here are some pictures with one picture being straight from the service manual:

Nice work! I will have to build a set myself, they look very handy.

Great idea - along the same lines - maybe? I have a set of heavy duty snap ring pliers. They have mutiple inserts (different size and angle stems). You could angle in the 90 deg stems to point inward and it might work in a similar fashion.

A little dyslexia there Tony there dyslexia?

I did a quick search on "fuel injector removal tool" and couldn't find anything like what you described. Get a patent quick!!!

And thanks for the tip.

I used Tony's tool last month. It was much smaller than I had expected. Seriously though, this had to of made the injectors easier to remove. I've read numerous posts about the injectors being a PITA to remove. Once I had the few things out of the way to remove the injectors, they came out in seconds. No issues and no scratched up intake. I was also impressed with the injector cleaning service. I swear, it now feels like my car has picked up .23 hp. YMMV

Thanks Tony!

I haven't looked at mine yet, but do the small holes go all the way through the injector? If so, could you just stick a small rod in them and turn it out like a cork on a bottle? I might have to hit you up for the tool later this winter.

Excellent idea. You might want to do the e-cheapo rout on a patent app. No huge prior art surveys etc, just the disclosure docs to potentially attract the interest of someone who'd make them commercially.

Well done!

Man, you sound just like my wife !!! But you did forget to mention how long it stayed hard

The holes do not go all the way through. I do know someone that just used a brake drum spring tool. He said it worked pretty well and I can attest no damage to the injectors.

Maybe some ricer injectors could use the same but either way the market would be limited....and that;s an understatement. I'm waiting for an idea like the gyrobowl
