Correct Injector Seals/Gaskets

[RI-SHO]

Sorry for the loq quality pics(i'll try and get better ones later tonight).

But are these the correct seals for the block to injector seal?

The smaller ones are the new seals Fred sent me and the larger is old torn seal, they look very different to me but fit the injector just fine. All of the other 12 seals for the injectors match exactly to there older replacements except for these last six which I know are replacement from Ford but just dont like right to me.

I just wanna make sure I can use them and still have the correct seal.

Newer replaced a year ago injectors on the left and older original injectors on the right.

What do you think couldve caused the older injector to have a lop sided circle(right) compared to the nice round circle of the "newer" injector(left)?

And the original's have DENSO - 18-NN stamped on the side the new ones have nothing stamped just these numbers on the body---> RIN-576 - 9114

Those are the ones. That is what my 11 year old seals looked like too. See the picture below.

Yes, those are the ones I got from either Nick or Josh last year. They seem to be more for securing the injector in the hole more than anything else. Maybe prevent any possible backspray. You're in good shape.
Nice comparison pic Scott.

if they are old injectors the fuel can some times wear a groove in the tube due to dirt and stuff in the fuel that can cause abrassion comming out at 30 to 40 or more PSI atlesast thats ehat i have heard from guys inthe jeep forum that i used to read, when i had a jeep that is.

Yea from my knowledge there original 1993 injectors with 123K, defitnaly need to be changed(well 4 of them do, 2 have already been chnaged). But i'm torn either upgrading to larger ones with a chip or breaking the bank with OEM new injectors from Ford for a little over $400.

Will Ford Motorsport 24lb/hr injectors work as SHO #24 3.0L injector replacements? And will they fit the fuel rail w/o any modifications?

You won't find these seals anywhere. You may think you found them - you did'nt. I did the leg work, I made all the long distance calls. You can get new 24# injectors that have the seals on them from ford. $30-35ea. Generally the upper seal with the double lip holds up well and should be reusable. There function is to 1) locate. 2) seal a air leaks(sucking). The lower seal is more unique, I ended up reusing the seals w/no problems. Some in dry/deteriorating condition. The "O" ring at the top is the CRITICAL seal for pressurized fuel and must be the correct size and/or in reusable condition.

Get the set from the SHOSHOP for 150 or 160.
