Injector Grommet... which is the right part?
Can somebody tell me what's the difference between these grommets (e.g. cushion rings)? The description calls one an upper and one a lower grommet. I'm only familiar with one - the one where the injector mounts to the rail. Here's the link to the description...

Thanks Yoda. I can't find that seal set on Beck-Arnley. Can you tell me how you located it? I see a "Injectors and Seals" but none of them are just seals by themselves.
Thanks,

Its got two on the top of the injector, the small o-ring that actually seals the high pressure fuel and then the upper grommet (on the right in the pic above). Then there is the lower grommet (the lowest one in the pic above) the seals the injector to the intake manifold to prevent a vaccume leak. Not real sure about the largest o-ring in the pic above (on the left)

the BA # on the napa web site is 1580090
Don't know if the link will work, but here goes:

The NAPA kit has even more seals (the CRB # 212080)

Here's what I used on my last injector project (Toyota P/N's, listed from top to bottom, I think):
O-Rings (top): 90301-07001
Grommets (top): 90480-13005
Injector Insulator (bottom, on top of spacer?): 23291-41010
Spacers (bottom, on intake manifold): 90561-10002
Spacer O-Rings (bottom, on spacer): 90301-23004
O-Rings (top): 90301-07001
Grommets (top): 90480-13005
Injector Insulator (bottom, on top of spacer?): 23291-41010
Spacers (bottom, on intake manifold): 90561-10002
Spacer O-Rings (bottom, on spacer): 90301-23004

Don't freak out when you pull the old lower insulator off and it looks nothing like what you have to replace it with. That lower insulator bakes and changes shape BIG time once you have 150k on the motor. The guy at the dealer was laughing when I handed him an old one and said "I just cant find the right ones" and he explained that to me.

IMHO, send them away & have the completely redone for only @ $13 each; I spent more than that on seals/o-rings alone!

Has anyone figured this out. I bought that same kit but the grommet that comes in the kit to go on the bottom of the injector looks nothing like the one that came off the injector. (talking about the injector to intake seal not the fuel rail) that one in the kit doesn't even fit in the hole on my intake. Are the proper grommets still available from the stealership? the one in the kit is basically a big fat O-ring, the one that came out of the truck was a lipped grommet nearly like the upper but with only one lip.

It just slides on over the pintle cover; there's not even a ridge.
I'd suggest warming it with a hair dryer (or hot air gun -- just be careful with that). That will make the rubber a little more flexible.
Keep in mind that you will likely pull off or tear the pintle cover; they are much more fragile than the lower cushion.

im replacing my injectors with the 4 hole. they already have a new cushion ring on them. im talking about my old cushion ring is stuck inside the grommet or injector cap or spacer (whatever people call it). its not stuck on the injector itself

The outer edge of the cushion is smooth, too. So you've just got something really sticky in there.
I'd still try a hair dryer. If you use a hot air gun, wrap your hand around the cup; if it's too hot for your hand, it's close to too hot for the plastic.

Your talking about the isolators. Just give them a good soaking with kroil or penetrant of your choice. I like kroil. Give them a few minutes and twist them back and forth then work them out. Obviously from my pic they do break but they can be bought from ebay.
