does anyone have the Stant numbers for both gas caps for 69 shelby
The tank recall gas cap wasnt a stant cap it was a non vented EF cap Emerson Fuller & the ford service replacement was different DOAZ.
My Cougar ones look similar . I can check if you like.
Someone has pic of the recalled one ?
Patrick
Problem is the original non vented cap wasnt serviced by ford & its a gm vendor cap. There is a smaller diameter gas cap for small filler necks. The doaz-A cap is the service replacement & it works fine but is a little different design & vendor change. The dooz-a cap is for the ca- evap system fillerneck. The correct stant cap g30 is the original vented type cap.
This one ?

Different neck used on California emission cars than the fuel vapor recall/campaign cars- looking through my pictures ::)
Notice Marcus referenced Cougars for the cap he shows in that picture. Not sure if he was referencing Cougars with California emissions but would guess so but he does mention the longer depth of the cap for that application.
Pictures I have for the D0AZ-9030-A are service replacements that match the picture in reply #5 and what Ed was mentioning (service replacements) in his post above.
If I am to understand previous statements ,the DOAZ cap is supposed to fit a regular 69/70 Shelby filler neck because it is a service replacement. The DOAZ cap like what Marcus has in his article will not fit the regular Mustang /Shelby filler neck. Maybe Marcus had one misboxed but it is doubtful. It has too tall of a neck as mentioned in the article on the backside compared to a regular vented cap on a 69/70 Shelby. I had one recently new in the box that I sold to West Coast Cougars because it would not fit any regular filler neck 69/70 Shelby.I have had a couple of them that I had purchased because the MPC number was has it supposed to be a regular replacement for 69/70 Shelby. I have a hard time believing I was so unlucky to have all three mis boxed because even though the MPC calls out for it as a replacement it will not fit. All I can say is that to pre test it on a regular filler neck before purchasing otherwise you may have a unpleasant surprise.
Has Doaz A always 2 brass rivets ?
Or could also be a center S stant ?

No . All the ones I have had look like the DOAZ cap in the article Marcus authored (link in reply#7) .
The cap in marcus article photo is 2 1/4'' od small type cap. The vented stant cap & the FE non vented (recall type) caps are 2 1/2'' OD . The depth of the gas caps are different depending on application also .
Here is a picture of the "recall" (I have the rerouted venting in the trunk as well) cap on my 1970 GT500. Is this correct?

Correct not vented recall cap not serviced by ford. The fairlane torino gas cap is the smaller 2 1/4'' cap.
Thanks Ed!

I have found the cap plated silver instead of black.
OK, I did some research. The recall included: tap a hole into the filler neck, attach a hard line in the neck and route to the edge for the trunk safely away from the exhaust, (wheel well?) Finish by installing a non-vented fuel cap. Reason was to prevent a fire from sloshing fuel out the vented gas cap, which was directly over the exhaust tips. Probably an over generalization.
GT500 only?
The fuel cap in the lower right hand corner is the one featured in Marcus's article. It did come from a 1970 California emissions Mercury Cougar. West Coast Classic Cougar shared parts for comparison, for research in his article.
Top left cap is a OEM factory 1969 Mercury Cougar cap, also the same as 1969 GT350?
Top right cap "ANTI SURGE VENTED". Stant stamped S, has a one-way check valve built into the cap. Auto parts store replacement cap or later Ford service cap for part number C7AZ-9030-A?
Ford MPC indicates 69/70 Shelby GT350/GT500 without ev/em, Vented-anti-surge-2.47" diameter, part number C7AZ-9030-A.
Bottom left cap "PRESSURE VACUUM". Stant and Autolite marked, also has one way check valve. Different service replacement?
Bottom right cap "NOT VENTED" Stant marked, does not have one-way check valve. 2.25" diameter.
The gt500 428 cj crossflow muffler heated the gas tanks causing fires from backfire or improper carb settings in the hot southwest heat is where most of the problems were. I have seen several gt500s that never had the recall done but they were northern cars from a much cooler climate area. On the recall the filler neck end vent indent was flattened back so a good seal was made so the not vented gas cap sealed tight to the now completely flattened neck. This was crudly done by hand with a tool from the inside outward.

Thanks Ed,
I noticed in the Ford MPC, there is a listing for a 69/70 GT500 fuel filler neck, part number C9ZZ-9034-B.

The top left was the cap used on 69 GT350 and GT500 until the recall on the GT500 only to the no vented cap. I would not drive any 69/70 GT500 that is pleasure driven without the recall . I know there are bound to be some out there that it hasn't been done to. It is not prudent to tempt fate. Do not ask me how I know. ::)
After conversing with Ed, this is the cap the dealer replaced my original one with probably at the first or second service. My GT-350 was built on April 14th and delivered on May 6, 1969. I did think at the time it was different, but never really paid that much attention to it until looking at this thread. After all, it has been almost 50 years.
It could have easy been switched anywhere or at gas pumps back in the 60s 70s the gas station
attendant pumped the gas for u before self-serve days & he would be pumping gas in several cars at one time & gas caps always lined up ontop of gas pumps & most looked the same but a little different as long as they screwed back on. I remember the old gas stations having a box of gas caps left behind from driveoffs back in the good ole days,
Hi, I am going to reproduce one Not Vented gas cap and I tried to identify the straw for vent off the air and I notice something... The vent is part of the filler neck. The neck has a notch that we have to unbend for proper seal with the recalled cap. Special Ed raised it on reply 18. See attach document. Hope it will help someone one day and we dont know maybe save a Shelby from fire.
Patrick
pat do u have an original non vented gas cap to copy & are u going to have them plated?
Ed. I dont have any original.
I am going to make one for me only( I made the correction on my previous post).
Yes I am planing to have it plated but with the squeezed gasket , I dont know how yet.
FYI I have started with AC Delco GT- 23 2 1/2 OD Not Vented stamped. Weld a FE handle.
