I have a 67 with 327 and factory air, console and gauges. There is a brass fitting that the oil pressure gauge connects to under the dash/firewall. The engine connects to the brass fitting at the cowl. It is the original fitting. I have talked about it to people at the shows who have it and all of them are using their original one.
Does anyone sell the Brass fitting on Cowl for 67??

Hmmm, sorry for the bad info. Not sure what the part is in that case. From his description, it sounded like the 1/8X1/8 NPT brass fitting that goes into the block right behind the dizzie on the block centerline. How does the oil line run from the block to the gauge cluster on a 67? Could the later setup be adapted to the 67 if he is not interested in the "from the factory" look?

Brass fitting is on the Firewall/Cowl like Mikes said.
It is between the A/C harness and the Wiper Motor. It pushes through from under the dash and a nut is attached under the hood. The fittings (and Tube) that attach to both ends are like the part that you read above. This part has the tube and fitting attached to both sides. That is all it is.
Mike,
There were 2 different grommets used in 67. A Brass one and a Rubber one. As far as I know, you can not get either. I will post a picture of the brass on My Pictures. Someone else can post the rubber. It was not the same rubber grommet as the Cowl Rubber Plug that looks like plug. You can see this correct rubber on page 386 in Factory Manual.

I think this is what Mike is talking about. Do I understand correctly that the original oil pressure line was plastic like the one in my picture?

Mike - You may be able to get something similar to that brass fitting at a plumbing supply shop but you will probably need a better picture than this one to show them what you need.

Looks like a 1/8 inverted flare bulkhead fitting.

Well I didnt think this brass fitting was correct. 67-69 are the same with the one piece nylon line and the rubber grommet.
Here's a post from JohnZ clearing this up - There is no brass fitting:

Definitely is correct on the 67 and maybe 68,(i don't think 68, but not sure). I can not answer for the 69. I do not remember. I don't know the percentage that had them, but for sure was used. I don't even know that it might be a small percentage, but the number of cars that have it will be siginificant enough to verify it is correct. If we keep asking this question and keep tabs of all that have it, you will find out it is the same fitting. Think about it. Everyone had the same idea with the same fitting????!!!! Would not make sense and does not make sense that it did not exist.
I have seen many Camaro's with the exact same fitting. I also saw it and tightened it on many Camaro's 30 years ago. For sure is an original part. You will also see many cars that have it and it is not used, because someone has ran the oil line through a rubber "Plug,"grommet #3868790, in the fire wall. The Brass fitting is a pain to remove and a pain to hook up under the dash, that is why you see so many people working around it, but still left it on the car. I have done it myself.
If you talk to old timers that worked on them many years ago, they will back me up. It is one of those weird parts and not in the Factory Manual. I already gave the page that shows the rubber piece above. Nothing in the factory manual shows this as being brass.
I go to a lot of shows, I will start taking pictures of it when I see it on a car and documenting it. I am crazy like that. Others do the same. You will see in a year from now the number will be significant. Get the date of car if you record yourself.

Mike, thanks for the update from Brian K.
I thought that was going to be one of those parts that no one believed, but I new it to be true as the memo apparently shows.
I did not know what the part numbers were, nor that you could even get the actual part number. Good Work.
For those of you not familiar with it, it was like make said a 2 PIECE PLASTIC LINE,
Plus Fitting, nut, wagon wheel lock washer and obviously the 2 nuts that attached the lines to the brass grommet.

Dale - That is exactly what happened with my car. The original oil line was cut near the guage by the previous owner and a one-piece copper line was run. The original brass fitting and part of the nylon line were left under the dash as you can see in my picture above.
My car is an 01B.
Pay attention to how it is together. Take it off and polish with a dremel piece by piece. Since they cut it, you will find that one of the line is stuck in it (most likely). Don't force it. Heat up the big brass grommet (while it is OUT of the car) and it will pull out very easily. Install it back the same way as ORIGINAL. ATTACH THE NEW LINE that is under the dash BEFORE YOU PUT THE DASH TOGETHER. This will make your life much easier. Dont worry about the line in engine compartment.
If anyone has these original line, verified original, I would love to know their exact length under the dash and engine compartment. Both line lengths. Also Daral, If that is a current picture once all your painting is done, install your passenger kick panel and your Y pipe NOW.
Mike, (Jonesy). We experienced car guys (like you & me)have to be careful when we say never. There are even more weird things than this. Even I have stuck my foot in my mouth. I now try to verify anything before I infatically say NO.
It probably did not happen, but you may find a week of cars in 69 that they used the brass again because the rubber grommet was on back order. We have to be careful if we are NOT sure. GM did what they wanted, they did not have a Bible. I thought it weird that so many people thought they had an original door, with the Remote Mirror Option, and no cut hole on the inside. Sounds weird, but I know that was really done. I think!!! LOL!

I guess when JohnZ, who worked as an engineer at Norwood, says it, then I would tend to believe him. They replaced the 2 piece due to leaks like the bulletin said. My 67 is unrestored and original and did not come with this setup. My cqr was made after the bulletin came out. It was phased out according to Chevrolet service bulletin. I have never seen it on 69 cars and I cant imagine the factory would go back to a practice that had issues.
I guess we both learned something about 67's. Yes, there are alot of urban nyths out there.

I did not learn anything. I new that it existed even if every person said that it did not. I was a mechanic in the 70's and new that it was original. You also have to be very careful when you say something about a 67 and you are comparing to a 69. That is a lot of time. Same goes the other way. Not trying to be a jerk.
There are many items like this on the car, because the car is made by people. And if they can not get something they will not stop production. I had a debate with a friend of mine a long time ago about the screws on the bottom of the 67 doors. Most people thing their are 4 and their are on most. But their are MANY that only have 3. Why, I don't know why ???? But, it is a fact. Is it documented? Probably not. But if yours has 3, leave it alone. It is true. I love stuff like that, there is alway an expert that says it is wrong. But it is true. If they took cars apart back in the 70's, they would know. If you were not working on cars and you were not paying attention back then, be careful what you say if you do not know. I have stuck my foot in my mouth more than once. I try not to any more. Even if no documentation existed on the brass gromett and no one said it existed, mine would still have it, because I know it true from experience not documentation.
GM made 100's of cars a day. Some days they made a 1000. Do you think there was not some lazy worker that thought 3 screws was as good as 4. Maybe he got fired, but that is the human element.
Moral of story: Be careful if you know something to be, "NOT true."

Well, I learned something too - 69's are my specialty (that's when I was at Norwood), and I wasn't aware of the "1st-design" '67 oil line setup; now I know the story too.
Thank you everyone for your help.
Especially Dale & John.
Dale had told me in a seperate email that no one would say it existed and that I still should not change it. That I would see it on many many cars. And John has proved the point. I know you guys dig this, but I just want to finish the car and not hit bumps in the road like this. I am really glad that some people know the answers. Dale I don't have the original lines intact so I can not give you there length.
Thanks again Dale & John.

Hi Brian K. here, I took a quick measurement of the firewall to engine block line and it's about 7 inches long. I dont have access to my inside line but the Chevrolet service bullentin says that dealers are to take off the junction, drill the hole bigger (1/2 inch in size) use the line thats inside the car to go to the block (it supposed to be long enough) and add the rubber grommet part number 3906193. Remember this is for people bringing their cars back to the dealer with oil leaks, that how GM told the dealer to fix it. The bullentin says effective June 5, 1967 the 2 piece design will be replaced to this one piece set up in production cars. My 11E build 67 RSSS has this set up owned since 1988, my original lines are white translucet in color. The current repops are black, I've found a good replacement from Auto Meter part number 990023 which looks and functions like original. Glad to help, I'm using my dads account here sorry for any confusion. Sincerely Brian Kotula
