fuel injector maintance diy

So I've found out how to jet the rail off . Yay me. Just wondering when I replace the orings on injectors should I lube the orings or leave them dry? 4/ 5 injectors are leaking from the orings

Lightly lube the orings with motor oil.

Thanks Austin. What the best was to clean them as well? Can I soak the tip in some carb cleaner or it that a bad idea?

Or send them out. ..

The car is my DD so sending them out won't be a option. I'll just replace the orings for now. Car seems to be running top notch

Kenny I have spare stock injectors if you want to send yours out.

LMK

I tried to remove the fuel rail and injectors today. I removed the black cover then un hooked all elec connections anx the vac line off the fpr. Removed the retaining clips from rail to injectors ( missing one ) then i removed the 2 allen bolts holding the rail to the mani. When i pulled up it would not come out. It seemed loose cause i could wiggle the rail.

Am i missing something here ? I dont want to break anthing i just need to replace the o rings here lol.

Thanks guys.

Ps yes i pulled fuse 17 piror to doing any work.

Pull harder...

Ok...will do lol.

How hard should one have to pull though? I was pulling pretty hard and no go. Any tricks guys?

I carefully used a breaker bar on the valve cover against the under side of the fuel rail for leverage but that was on the.3B..

does the can of carb cleaner provide enough pressure for the injectors to work? or should they fire if there is just unpressurized fuel in a similar setup?

The injector is being triggered by a battery while cleaning it with carb cleaner.

Ill give the 2x4 a go and see if that works. Fuel injector 4.is the leaky one and 2-5 are following suit. Ill tackle that this week since im missing a retaining clip which ill need to pick up.

Has anyone had issues with stock injectors not sitting properly in the fuel rail. FI 5-4-3-2 all fit property and have the retaining clips. But FI 1 I can't seem to fit the retaining clip on. The fuel rail seems to be sitting about 2mm higher on that injector and I think it's leaking from between the fuel rail and the injector.

Has anyone ever had this issue? What's the best way to fix this? Do I bent the mounting plate/ bracket a bit ?

I'll post a pic tomorrow so you have a reference,

Thanks again guys.

LMK how the spare rail and injectors work out. Be sure to swap over the new o-rings, just because.

Yeah. I'd invest in getting some injectors that aren't that rusty.

No rust buddy's, that's sand and dirt built up on the injectors. There much better now I should have taken before and after pics.mm
