Last week I noticed seepage on my #3 injector at the seam between the metal and plastic... so this is what I ended up doing. I know that some others out there have done this and I think some others are thinking about it. This was done on to an 88 chief 4.0 RENIX 5spd with 200,000 +miles and injectors of indeterminate age.
What I used
13mm socket
5/16 socket
T20 torx
Dielectric grease
an Awl
small dish to put gasoline in
mopar pt# 1-83503637 O Rings
mopar pt# 8350274 Repair kit (these are the new quick connects, 1 per pack)
6 Mustang 5.0, 19# type III fuel injectors
1. unhook your battery and all vac lines ect. that are in the way of the fuel rail. put your o rings in a small dish of gasoline to soften while you work.
2. unbolt the fuel rail, label each injector plug, take your awl and unclip the small metal springs that hold the plug onto the injector
3. release pressure from the schrader valve and undo the quick connects at either end of the fuel rail. A towel or such to soak up the gas that comes out is a good idea. pull all the old o rings, spacers, ect from the female end of the quick connects
4. rock the rail back and forth until the injectors let go of the manifold.
I had alot of crud built up in the manifold holes so I used a small piece of hose duct taped to my shop vac to suck it out...
5. Remove the clips that hold the injectors onto the rail and set them aside.
remove the fuel pressure regulator and take the o ring off and discard it.
6. Install the o rings onto the injectors and the fuel pressure regulator. carefully reinstall the pressure regulator
7. Install the new injectors onto the rail (I did not put any clips onto the injectors to hold them to the rail)
8. set the rail in place and rock gently to reinsert and seat the injectors.
9. put the spring clips back onto the electrical connectors, insert the new quick connects into their respective females...
10. reconnect the fuel lines and bolt down the rail.
11. connect the electrics
12. reconnect the battery and anything else that you unpluged.
start it up and watch for any leakage...
I am not resposible if you light your jeep on fire from following my instructions...
Some things I learned... you can get O ring kits at Napa for alot less than the dealer... you can also get the quick clips from standard motor products inc. part #HK7(car quest and auto quest?)
I got my injectors on ebay because im too poor to buy new right now... but check out fiveomotorsport.com they have the best prices that I found and are really nice to talk to. good luck and thanks to 5-90 for sending me some info on these injectors...
