Correct 6462137 reproduction oil sending unit..
 

Has anyone reproduced the sought after 6462137 1969 to 70 with gauges oil pressure sending unit yet? I thought I had heard a few years ago that Inline Tube was working on it.

I wish someone was making them,I could use at least 3 of them.

I emailed Inline Tube so waiting for a response. John Kryta once posted on here a while back so maybe he will chime in.

Seems this 80 PSI unit was also used in large B cars with rally....also used on other GM cars....any luck what a good replacement part number. Nothing can be found out there.

It would really be NICE if Chris C or the Krytas or Steve Anes would look into correctly reproducing this style Rally Guage oil sending units.
Believe the correct shaped application would be '68-73, at least till the Introl style Rally Guage oil sending unit was phased in. Personally, I'd like to see this version properly stamped with the correct part number.

Through the 80's into this Century have always pulled original Rally Guage oil sending units when I came across them in yard cars, on engine cores, & from engines from own parts cars. Fortunately, have set aside for ongoing restorations most of the original rally sending sending units I need, but like with last acquired '72 project, the original rally sending unit is long gone. I'm not buying one of the white plastic insulated tip repro's that is currently being offered. The later 70's Introls are more correct (hate that choice of words) than the current reproductions.

'67's B series had the short squatty bodied Rally Guage oil sending units like a '65 or '66, no? Been a long long time since I've pulled one of those, do have an original off a '66 421. Will do further ck'ing.

Here are a few I have. In the first picture:

- Top Left is the acorn style used prior to 1970. This particular one is a 60lb unit for a 1966 Olds 442.

- Top Middle is a correct 6462137 dated for my 71 TA.

- Top Right is an NOS 6460032. I have seen these be used in place of the 2137 as they are 80lb units and have the same 1/8" NPT fitting.

- Bottom Left is for a 71-72 Buick, note the 1/4" NPT fitting. This is a 60lb unit.

- Bottom Middle and Right are again 80lb units with the 1/8" NPT, but the number is 6461967 on both. I believe these were used for testing as they still look pretty new but appear to have been used a bit. They are both stamped "DUAL", one with ink and the other stamped in the housing itself. Not sure what the means.

-The "137"s were def used on '69 Pontiacs as the original is on our 428 HO GP.
-The original rally sending units from my '71 HO cars are "137"s as well.
-At some time these went from gold cad finish to being black.
-The original "137"s on my '71's are black.
-the late '69 dated ones off '70 production builds that ive had in the past were a faded black finish as well.

I think the can shell of the 137s was initially black for 69-71 but switched to just being gold zinc by 72. Note that the bottom base part with the threads was gold zinc for all. The 137s were also used on Olds. In 73 the number was changed to 6463727 and these were all gold zinc. The earlier acorn ones I have seen have all been gold.

Will ck what finish my late '72 T/A's sending unit is.
Was 6463727 the INTROL version, I've forgotten?
Years ago I parted out a rusty April or May of '73 built LeMans GT with factory guages & have the oil filter adapter with original sending unit on it, In hauling boxed parts over, so have yet to run across the box of oil filer adaptors but know I have that box.

No, the 3727s look just like the 137s.

Hmmm, I will find the 73 original units.

Do have some of "032"s, they work fine in a pinch.

Thanks for this great info.....In breaking it down and focusing on 80 lbs. units only:

-6462137: First pic, acorn type, was a valid part number until 69

-6460992: Second pic, superseded 6462137, in either gold cad or black finish depending on application. Also found this link on eBay, someone is selling an NOS unit for 700 bucks, a bit more than what I want to spend.

-15591103: 3rd Pic, is this the one that is referred to as the INTROL unit?

You have these backward. 6460992 is the acorn style (first pic) and 6462137 is the can style (second pic) that came after the acorn style.

Also, I don't believe the color was aplication based but rather time frame based.

INTROL (bell shaped) oil pressure transducers (sending units) started some time in '74 with the '74 models.
Agree the '2137 were painted and the '3727 were plated and the date change was '71/2 timeframe. To me the shape was the same for both and should have been easy to repop in plated (paint to match).

Agree but I am pretty sure the 3727s didn't arrive until the 73 model year. I have seen 2137s on 72 Olds' and those were gold. Also, in my pic above the Buick one is a spring 71 date and was painted black. Putting this all of this data together I am deducing a bit that there was consistency across makes as this is just how the supplier produced them.

What I don't get is why there are so many different numbers that seem to be the same unit, 80lb with 1/8 NPT. The one I currently have on my TA is another number different than these. Works perfect, looks correct and unless you are hanging over my passenger fender, you can't really read the number anyway.

So '72s were still stamped '2137? That I didn't know.

I dug further into my stash and found another 2137 I have. See pic below. The black is the one from my prior picture above dated 223 0 which is perfect for my 71 TA as it matches the other engine components. I was lucky to find it. Next to it is another 2137 dated 052 3 that came off of an Olds (you can see the long Olds adapter still attached) and was gold. So, it looks like the 2137s were made into 73. Not exactly sure when the 3727 started, if it was later in 73 or if Pontiac switched numbers before Olds. Again, I don't even know why the numbers changed as they seem like the same thing.

The third one is NOT the Introl unit. That is just a standard later replacement. The Introl units were more of a dome shape and stamped Introl up by the electrode. I think there are pictures in an old PY thread of one.

Correct!! I had one of the first "pattern" 69 Judges back in the early 70's, without a Judge emblem on the glove box. The rally oil sending unit was the 137 and it was painted black, almost matte or flat.
