How to replace injectors guide?
codeman:
Thank you for the help.
Does anyone have a part number for the heat shield?
And is there anything special about the rubber pieces connecting the fuel injectors? Can I just take some normal 'rubber' hose and silicon the end closed?
Is using an impact gun advisable for removing the injectors? (obviously not installing them)
ORCoaster:
Can't say I have ever seen a part no. for those heat shields. I think Rock Auto has them listed.
I have a ton of used ones so if one gets a crack in it I toss it and get another.
You need to connect the injectors back to the IP in some manner. I use a Tee between the second and third cylinder as it lines up better with my pump and other hoses. You can get 3.5 mm hose that is fuel rated and join them up. As for the far end one? They do have a special plug for that but a piece of hose with a bolt in it works just fine for me.
Those hoses take the fuel that was not used for combustion back to the pump where it can get routed back to the tank and then back to the pump for a second try.
Impact gun is an option for removal. Just be sure you have the right sized socket and hold it firmly. Don't want it bouncing off injector.

Right, I put a T in between the #3 and 4.
Actually I run a line from 1 to 4 and have a T in it for the line that goes back to the pump.
Instead of plugging the end one.
You can put the T anywhere so you can pick a place where it lines up but doesn't rub on anything.
I often use clear vinyl for those lines,.. 1/8".
AutohausAZ is pretty good about keeping the part number next to the part: 068130219

Damn, $10 each. That's the highest price I've seen.
Glad I have a stash of them.
I would only use an impact to break it loose.
A very short burst.
And that's only if I was having a problem breaking it loose by hand.
Just hold that extension straight up from it.
The impact was more an example of a force that doesn't pull the injector in any sideways direction.
Just twist them out.

Thanks for the tips. I noticed your user name, are you on the Oregon coast? I'm in Bay City.
