Im in search of an injector rebuild tutorial that I seen on here I think. When I goto search and hit search titles and put in injector rebuild, I get three results. So Maybe I didnt see it here, but somewhere else? None the less, does anyone have a good tutorial on how to clean these things? I did some looking around on the net, but I liked the one I thought Id seen here.. If no tutorial, what about some tips, what to use, how you powered them etc Thanks guys.

Rebuilt ones which are flow tested using specialized equipment and electrically verified aren't too expensive. Did you consider going that route?

yeah but I got a set for 30 plus 12 for the rebuild. I dont think the professional could be THAT much better, I mean I know ti would be but ehh its always fun to do things yourself.

I rebuilt mine with the mr injector kit and flushed them using a one man brake bleeder vacuum pump. Worked perfect. I opened them connecting wires to them and tapping them on my spare battery terminals.





Here is a link to a kind of a tutorial I made too...kind of bad camera angle, but it gets the info accross:

Programbo

You can get a big turkey basting syringe and push the cleaner thru the injectors with that also

From most of the stuff I was reading it doesn't do much to knock free the sediments when you flush them unless you have pretty high pressure flowing through them. That's why I used the vacuum pump so that I could get about the same pressure that the fuel pump puts out. Some people use compressed air which would work too.

Programbo

If you reverse flush them you are pushing the sediments out the large rear side instead of thru the tiny pintle holes so you don't need as high a pressure to push the gunk out.

Thanks all.

I posted the following on another Jeep Forum several months ago. I realize the injectors used in Volvo’s may be different from the Jeep version (see the section regarding the “needle valve“), but it may stimulate additional discussion about cleaning fuel injectors.

The original post is as follows:

My neighbor is a retired airline pilot who still flies and maintains his own private airplane - a Beech Bonanza. I discussed aircraft maintenance with him and he mentioned that he regularly removes and cleans the fuel injectors on his airplane engine. Rightly or wrongly, he is convinced that adding a FI cleaner (such as Red Line or Seafoam) to the gas tank is not sufficient to properly clean injectors.

That got me thinking about doing the same to my Jeep so I did some research on this subject. During my travels I stumbled across the following site with a section on cleaning INDIVIDUAL fuel injectors at home:

http://www.volvoclub.org.uk/faq/EngineFuelinjection.html#Injector_Cleaning

A portion of the narrative is as follows:

“[Lyle Domico] I was able to use a Mityvac to back flush my injectors with straight FI cleaner. Pull the injectors and strip off o-ring seals. Pour a little cleaner in a spray can cap. Set up your Mityvac with the brake bleed bottle attached. Wrestle the Mityvac hose onto the top fitting of the injector. Set injector upright in the cap of cleaner and pump up the vacuum. Gently press down on the injector to open the needle valve on the bottom and the cleaner will start to flush up through the injector, effectively backflushing it, including the screen.”
