replacement gas cap

[tocheck]

Stopped at the station to fuel up this morning and couldn't get the locking gas cap to open (key wouldn't turn). Anyone replaced theirs and know what the part# was? I am thinking about going with a non-locking cap.

Thanks

I'm pretty sure Superformance and the Backdrafts use the same filler / locking caps assemblies. Both cars made in SA.
(both caps appear the same and the keys have the same cap manufacturer logo "PJ")

The non-locking for the SPF is NAPA 703-1687. I'd give it a try.

One thing of caution: This may be a non-vented cap. You may have to mod it with your trusty drill.

Edit:
The Moto-Rad (manufacturer) site shows fitment on a 1978 Corolla. Which is vented.

Thanks Spdbrake! I got it open last night but it needs to be replaced. I will be trying the NAPA part.

Quick update: got the NAPA (stant) gas cap. It fits the hole perfectly, problem is the black handle keeps the cover from latching. I will post again when I decide how to deal with this.

Using the information above, I now have a non-locking vented cap. I found the locking cap to be an annoyance.

When you order the above part number, this is what you get. The caution on the top tells you that it's not a vented cap,



But, a minute or two with a small drill bit and it's vented, with a baffle.


The chrome cover is just a smidgen too large to fit inside the Le Mans cap. So I tossed it out.

As mentioned, the plastic handle sit up too far, and interferes with the spring bolt on the underside of the Le Mans cap. A few minutes with some sharp tools, and that problem is resolved.


Voila! The perfect fit.
