DAVES89 Posted April 3, 2013 Share Posted April 3, 2013 When my buddy was putting the fuel rail back in he noticed [after we replaced the O Rings] that there was little split flat washers on the outside edge next to the O Rings. As luck would have it I had an extra fuel rail that I picked up from that guy in Indianapolis. We were able to use those washers. Question I have is that AutoZone had no idea what I was talking about, so were they really needed? Or do I pick them up at a Buick dealership?

2seater Posted April 3, 2013 Share Posted April 3, 2013 I would think one of the injector reconditioning places could supply what you are looking for. I am assuming you are talking about the end that inserts in the intake manifold? I looked at a stock injector and there are two small spacer rings, one on either side of the O ring. The upper one appears to be solid and somewhat thinner than the the lower split ring. I thought they might be to reduce the clearance between surfaces to compress the O-ring a little more but they just appear to be spacers to locate the O-ring where desired. The metal cap on the end is threaded and can be removed (it is tight or threadlocked) to install non-split rings. You might consider sending a set of injectors out for reconditioning as a spare set and perhaps have the missing part(s) replaced. Link to comment Share on other sites More sharing options...
Ronnie Posted April 3, 2013 Share Posted April 3, 2013 I'm not sure which part you are looking for. Do you see the part in this seal kit?ACDelco 217-1379 Fuel Injector Seal Kit - The Reatta Store Link to comment Share on other sites More sharing options...
DAVES89 Posted April 3, 2013 Author Share Posted April 3, 2013 2seater your description is correct. I am looking for the 6 split ring washers that are on the "business" end of the injectors. As luck would have it between the two rails I had enough washers to do the job. I would be interested in sending my back up out to be ready should I need them. Where would I send them? And are all year injectors the same? Also about how much would I be charged for this service? And lastly they would have all the washers and replace them?

DAVES89 Posted April 3, 2013 Author Share Posted April 3, 2013 Ronnie the O Rings are correct but not the washers. They are flat plastic washers with a split in them. A survey question... Are they really needed? Link to comment Share on other sites More sharing options...

DAVES89 Posted April 3, 2013 Author Share Posted April 3, 2013 I don't know what color they were new but when we replaced them they were brown. Link to comment Share on other sites More sharing options...
2seater Posted April 3, 2013 Share Posted April 3, 2013 I have used these guys several times with no issues as well as purchase of some of their electronic components. Actually I have met the owner several times at Buick events. There are certainly other services out there and I would think you would need to contact them if a particuar level of service is needed. Specializing in automotive interconnect and wiring systemsRegarding the question of them being needed, I do not know. Since the manifold is drilled straight through, with no sort of step for it to seat against, it would depend on where the O-ring ends up when installed. The cap on the end is quite small, and may not provide enough of a stop to keep the O-ring from being sucked off the end? It is not uncommon for the O-ring to be pulled off the injector when removing after many years of service. I suspect the rings are not commonly available at a FLAPS due to low usage. I have several different styles(brands) of injectors and the stock ones are the only style I have seen personally that use that particular arrangement.

Machiner 55 Posted April 4, 2013 Share Posted April 4, 2013 Dave,The reason I askedis because I once replaced the seals (O-rings) as well as the plastic washers on my '89 Riviera. The washers were banana yellow. The color may be a size guide (yellow for this size, brown for that size etc. I don't know for sure. I searched high and low for replacement rings. None of the flaps had them or knew what they were. I ended driving to Crown Point, IN. (about 15 miles from me) to a NAPA store that had them. That's all I got to say about that.John F.

Guest Mc_Reatta Posted April 4, 2013 Share Posted April 4, 2013 Dave, The washers were banana yellow. The color may be a size guide (yellow for this size, brown for that size etc. I don't know for sure. At one time there was a movement to color code o rings based on material/application. Yellow would have indicated a ring made from FLUOROSILICONE or HYDROGENATED NBR recommended to be used gas/fuel systems.The movement was not adopted by the industry, so most o rings are black no matter what they are made from. At least many of the rings meant for use in AC systems still are made in a green color.A good reference guide to o-rings can be found here if anyone's interested:http://www.parkerstoresakhalin.com/prod/uplot.pdf Link to comment Share on other sites More sharing options...
Machiner 55 Posted April 4, 2013 Share Posted April 4, 2013 McR.,I understand about the color coded "O"-rings but, I was referring to the plastic spacers (washers).John F. Link to comment Share on other sites More sharing options...
DAVES89 Posted April 8, 2013 Author Share Posted April 8, 2013 Just got back from the Buick dealership and it looks like there has been a change in the fuel rail washer situation. It appears that now a plastic sleeve goes on the rail end and then the O ring is installed over the sleeve. The G.M. #19178978 sells for $29.08 Or you can go Dorman and the part#90101 sells for less then $8.00 Link to comment Share on other sites More sharing options...
