Correct 1966 Gas Cap picture

[455hota]

My 66 Lincoln came with a locking gas cap that had been drilled out( lost key??). I want to find the correct type of gas cap. Does anyone have a pic of their known to be original and correct gas cap from their 1966 Lincoln Continental 4 door sedan? If so can you please post a pic? Thanks.

I know it's a vented cap but that's all I know.

How's your car coming along?

It’s this style but mine is aftermarket.

My original was not sucking air in as the tank drained.

Here are some, I had a book somewhere that listed them, but.....

My car has the same one as Dans, but the one I took off looked identical to the one from my Buick (lower left). To the best of my recollection, the other 3 are, top- closed vent, emission era (has a plastic valve and usually has "pressure-vacuum" printed), middle- open vent, This was used on your car, just an open hole. Bottom, non vented, used when the tank is mounted low and fuel could slosh out, a separate vent is required, my '62 has that type. You need the top rib, as there is little room to reach around and grip it.
Sorry, TMI again.

So from what you guys have posted, this type of gas cap is not correct:

I need to find a vented one with the “finger bracket” attached across the middle of the cap, correct?

This one is off my 67 Tbird, but it it too large to fit on the 66 Lincoln filler neck:

If you can comfortably take it on and off, it is fine. It says vented, I think you will find there is a hole in the middle. When they added a charcoal canister, they added that plastic valve, but both types are vented and will work.

Actually there is a one-way check valve in the middle. It seals when the tank pressurizes, then it opens up when the pressure reverses into a vacuum.

Personally, I prefer the locking variant. It secures the fuel supply from theft or sabotage, and it's not that out-of-date; locking caps were optional extras Lincoln offered since at least as far back as '65. The factory offerings are just hard to find these days, as hardly anyone paid the extra for them; in '65 one didn't have to worry all that much about having their gas siphoned out, or contaminated with sugar or mothballs.

Here’s what the factory locking cap looked like

O, cool! So there is a visual record of them! Aside from the labeling, it looks like my aftermarket lock.

Thanks for the picture Lee. Do you know if the Autolite locking cap used on other year Lincolns?

My '63 had a locking cap when I got it. I don't recall if it was an Autolite. I took mine off and replaced it. I'm sure the old one is in my old parts bin. We're repainting the garage while my Lincoln is at the shop. Needless to say, it's a mess so I can't dig it out to look.

Mark, there are references I’ve seen to them being a dealer accessory nearly every year, but the only illustrations I’ve found are for 1969 (the one above) and 1962, which is below. The 1962 version looks different, and has a 1961 part number. Ford purchased Autolite in 1961, and I assume the dealers started using some “off the shelf” Autolite branded cap shortly thereafter. When, I have no idea.

Interestingly, this list also shows a PN for optional rear seat belts in 1962, which I didn’t think happened until ‘63.

Here's the picture of the gas cap from the LCOC 66-69 Authenticity Manual.

It says VEN TED above the flat area of the tabs.
It says ANTI SURGE below the tabs that stand off the cap.
The center rivet appears to be a capitol S as in Stant.

This matches the T-Bird cap shown above. I believe this is correct for Lincoln as the T-Bird cap is also a Ford product.

Steve, here are 3 that all fit my '67, the one in the box has extra redundant lugs, some kind of safety thing because just so many of them fall off I guess. I am pretty sure I don't need a stockpile of '67 gas caps, so if you want that one, I can send it for about $25 shipped? Or the 2 lug one that Looks like the authentic one Dan posted, but it may be cheaper to just get one locally.

And here are those truck grills we talked about, '61 and '62.

[TonyC]

The non-lock cap on my grand's Man-Of-War was exactly like that, so the authenticity manual is correct. I know Frankenstein had the same when I got him, but getting a locking cap was one of the first upgrades I did...even though that was irrelevant at that time: With the perforations all along the bottom of the tank, a locking cap would not secure any gas.

I must say, it's a neat little revelation of history to learn that Lincoln offered locking caps at least as far back as '62 and likely '61.
