1958-60 Eaton cap part number

[Ian G.]

Does anyone have an Eaton gas cap catalog and can advise the Eaton part number for the 1958L-1960 gas cap?
From my research it doesn't appear the Eaton cap 3764641 was ever available from GM in service...

Ian,

I don't have an Eaton gas cap catalog but I know someone who has a NOS Eaton gas cap that looks (as best as I can remember) identical to the 3764641 gas cap as shown in Noland Adam's 53-62 Corvette restoration book on page 239. I will post a photo of the cap along with a description and dimensions in the very near future.

I have a 1975 Stant catalog which lists Stant gas cap # G-40A as replacement cap for 53-62 Corvettes. There also is a drawing of a G-40A cap with the following dimensions: O.D. = 2 17/32", Inner ring dia. = 1 1/2", Height = 1 3/8". This G-40A replacement cap was also used on other Chevrolet models as well as Ford, Mercury, and Pontiac models. I suspect the 58-60 Eaton gas cap was used on various models as well.

Thanks for the info! I think the G-40 is the vented cap correct for 61-62. I think the G-38 is the non-vented Stant for 58-60. For Eaton, I saw an EG-38 which was vented, so for 61-62. I'm trying to figure out what the Eaton number would be for the non-vented cap. I just like the Eaton

Dave -

No, they use a non-vented cap.

Re: 1958-60 Eaton cap part number

I was thinking that, since they came out with the vented cap in 61 or so for the gas sloshing thing right? Sorry ignore me. I have a 59

Currently there is a NOS 3764641 VENTED gas cap on Ebay (not mine). The word "VENTED" is stamped on the cap twice as well as the Eaton logo.

I am still waiting for the photo of the Eaton cap as mentioned previously.

Re: 1958-60 Eaton cap part number

Enclosed are photos of another VENTED Eaton gas cap currently owned by my brother. The word "VENTED" is stamped twice with "Eaton" stamped in a 1/4" dia. circle. The cap measures 2 1/2" O.D. with the inner ring measuring 1 1/2" in dia. The cap is NOS but without a box. Note that the Eaton logo on this cap is stamped at a different location then the cap currently on Ebay.

Re: 1958-60 Eaton cap part number

Yesterday at a swap meet in Stafford Springs, CT, I found the gas cap pictured below. It looks loke GM # 3751027 as pictured in Noland Adam's 53-63 restoration book Vol. 1 except that it has the word "VENTED" stamped on it. The letters "F" and "E" must represent the manufacturer, Fuller-Emerson. I do not believe that this vented cap was an assembly line cap.

Dave, Unfortunately that is not a Corvette gas cap. May be appropriate for a passenger car application in the late 50's or early 60's.

Does 60-61 use a vented cap.?

The only model years that used a vented gas cap were 1953 to early 1957. During 1957 production GM vented the gas tank. As such, there was no longer a need for a vented cap.

Dave,

Because the cap is vented I did not think that it was correct for a Corvette but it only cost me $1. As you stated I also believe that the cap is from the late 50's or early 60's. It might be a service cap but it also might be an assembly line cap.

Re: 1958-60 Eaton cap part number

My 57 Corvette #809 (November 1956) came with a vented Eaton gas cap and no tank vent.
Later in the production year the tank vent was added and a non vented cap was used.

Not sure if this helps but here is a picture of my 58 gas cap but I'm not sure if its original or not ??
