Hello,

My march 1970 240Z got a new fuel cap with chain.

But I also have a non-chain cap.

Which is original?

Please let me know someone.

Thank you,

kats

kats,

My gas cap does not have a chain. However, it has grips on top of the cap and this is very convenient for my fat fingers!

My parts fiche lists 17251-E4101 as the original gas cap. The supesede number 17251-E4102 describes the cap with chain and four later numbers all describe the cap with chain. The first date associated with the third cap upgrade is 4/72.

I personally do not like the chain because the cap could scratch the paint. I think you have the option to decide depending on the date of your car. Clearly the first caps came without the chain but it was added quickly. It is quite possible a 3/70 build date would not have a gas cap chain.

Nice gas cap, kats!

My gas cap has no chain. The parts fiche lists the gas cap 17251-E4101 and five supesede numbers. 17251-E4102 is listed with chain but no application date. The first supersede number to list an application 4/72 date is -E8800. It is quite possible an early build date of 3/70 would have a cap with no chain.

I personally do not like the chain because the cap may scratch the paint.

Hi Kats:

The cap with the chain was OEM for the US Spec. 240-Z's. The rubber pad was there so the cap wouldn't scratch the paint as it hung on the chain.

kind regards,

Carl
