Vented petrol cap

[1963 S1]

Are petrol caps, for the early Elans, vented? I assume yes; unless there's another point between the petrol cap and the fuel tank which serves to vent. This is for a Series 1 Elan, however may be the same for all Elans. Thank you for clarifying.

Hi there,
Refer to the link. You can see a vent hole in the annular, hollow ring. There is another vent hole on the other side of the annular ring, 180 degrees apart. The 180 degrees stops fuel from sloshing out of the vent holes.
Cheers Colin.

Thank you for your replies. If anyone has a spare petrol cap, as shared by Vaughan, which they would be willing to part with please let me know.

That looks like a radiator cap not a fuel tank cap........................?

[vstibbard]

Its definitely a fuel cap, its the original set up of a Feb 64 Elan, Overall and seal diameter is larger than any radiator inlet and its vented.
