Seems that nobody has posted about locking gas caps for a while now, and with the price of gas going up again I thought I would share a great deal that I got with you all.
I could never find the correct model of the Stant gas cap that I've read about a long time ago on this site, but I noticed that Target carried Fram ones the other day. I used Fram's on-line application guide, and found out that their gas cap with model # of 504 should fit my 5.7L Tundra. I was pleasantly surprised that Target DID carry that model # and it was only $10.99!! I put it on, and it is working great so far (2 fill-ups so far). My check engine light has not come on at all, and it is not coming loose. No leaking either- as I've read about on other posts.
I will be sure to post any updates if any problems arise, but so far it works great and I just wanted to share how easy and cheap it was to finally find a locking gas cap for my truck!
Hope you all are doing great. It's been forever since I've posted on this site!
