'61-'62 large tank gas cap?

[Rob Edwards]

Ok, so a little knowledge is a dangerous thing. When I took over the '62-340 I take care of, the 'wrong' gas cap was on it. I just got the '61-'62 Restorer CD (a great product, for those considering it) and I came across an article on gas caps from the Summer '79 issue. In it there is a picture (Figure 7) of a 'big tank' cap, P/N 3784892 or 3798770. Well, it looks a lot like the cap I have, though there's no part number on my cap. My cap has a very crusty cork-like gasket on the inside and has a fine knulring pattern on the perimeter. The car is NOT a big tank car, so I've no idea why it would have this cap. Since there is no P/N, I will assume this cap is NOT a big tank cap and is some generic Napa part, but I'd appreciate it if someone could pass judgement on these pics. Thanks!

A few years ago I bought a rough 57 and it had the same looking cap on it. I think they are aftermarket.

Rob, Looks about right to me...

If it fits your fill pipe, then based on what I see in the picture, its probably a "big tank" cap. That also means it was used on other Chevrolet models like some pickup trucks of the era. Dennis

Same cap as used on a...truck? Gee, that takes all the fun out of it.

I figured as much, thanks for the input, gentlemen. Hey, perhaps it's worth as much as $2 to someone at Pomona, right?
