Thanks,

My car quit running and I can't get it running again until I find this part, or some other workable solution!

Here's the info I posted on Facebook:

I am in DIRE need of the following part for my '93 Cadillac STS. It has been discontinued, and I can't get my car running until I find it!

Pressure Side Seal Kit--GM# 17112862

This is what the mechanic e-mailed me:
"Where fuel supply line connects to fuel injector rail. We need o-ring and retainer clip or 3 o-rings. NOT REPEAT NOT fuel injector o-rings."

Please let me know if you have any ideas or suggestions!


I was never able to find this part, and the mechanic ended matching up an O-ring and, since he didn't have the clip, put in 2 additional o-rings to hold the 1st on in place. It failed after 2 weeks. He said used parts won't work because it is an o-ring. I don't know what to do. One friend said that there was a recall on this part for '93 Cadillacs, and that may be why it is discontinued.

hey steve
i had my guy look into it and he says that isn't a good part number and that there was a recall (Recall 93V088000: Fuel Lines Defect) for 1993 eldorado and 1993 seville with the 4.6/4.9L engines. Maybe thats why they aren't available.

Have you tried to seek a complete line from the filter to the fuel rail?

I have not tried to seek a complete line. I was going to buy the complete intake manifold from a junkyard, but the mechanic I was working with said that wouldn't work because they would have to remove the O-ring to remove a bottom bolt, and then we would again be working with a used O-ring which he insists we can not do. Is this something that you think I might be able to purchase new and would include the O-ring and the retainer clip?

I guess I am not understanding what o-ring you are talking about, in the fact that replacing the intake manifold would include it. If I am remember correctly, there is a fuel pressure line, and a return line that connect to the rail. These are of a quick connect type, and part of the lines, the metal clips are more of a safety device to prevent the lines from coming disconnected.

If you can get a GM picture of the intake it is GM picture or diagram # GM03-266. On that diagram it is item #'s 38 and 39 that I am looking for. I was told yesterday that this part is never replaced and is probably why I can't find a factory part. I was told the Fuel Pressure Regulator goes out quite often, but not this o-ring/clip combination. The service manager I spoke with said the mechanic probably damaged these parts somehow and now can't get replacement parts to fix it.

I see what you are speaking of, now. I don't see any reason someone would have disturbed that in the first place, and I don't know what bottom bolt it is interfering with. You are probably not going to find them parts new, and while an o-ring may be attainable through a kit or matching it, the clip will be next to impossible to find new. The wrecking yard intake may be your best option, and you should not even have to remove the cover bolts to change out the intake, so the connection illustrated should not need to be tampered with.

The mechanic who worked on it said no parts from a salvage yard would work because it is an O-ring and a used one would not work. He was very adamant. It appears that my choices are to try something used or junk the car. I would like to try something used!

I live in Tomball. Can you fix it or refer me to someone who can? I am leaving Friday morning for Arkansas to see my mom (in a Rental Car of course), and would love to get it to someone that could work on it and maybe get it fixed by the time I get back Monday afternoon. You can e-mail me directly if you get the message and can reply before 4:30 today. Srowland576@yahoo. Com.
Thanks!

If you were to get a complete used intake, you would not have to tamper with that connection, so I don't see why it would not work. Basically, you remove the four bolts that hold the intake down, throttle/cruise cables, some electrical connections, electrical connections, and possibly an egr tube, and you swap it out. I live on the other side of the country, and have no references to your area.
