Gas cap question

[TMA62]

Greetings:

On my 1971 Avanti II, I have the orginal gas cap. However, over the course of time, the rubber gasket has lost its suppleness and can't hold gas in (after a full tank fill up, the gas will leak out and you will see the streaks of gas on the rear fender area....and no, I don't fill up to the very top of the tank stem)

I am looking for a replacement cap. I believe this cap was made by Atlas and has "Pressure Vacuum". While looking on Ebay, I have found Atlas caps that look like my original but have "Anti-Surge Vented" on the cap. What is the difference? Would these be a good replacement?

Also, are there ways to attach a new gasket on top of the old one? What have you done?

Thanks in advance!

Ted

You shouldn't have to have a vented cap, since the tank itself is vented.

New caps are available from NAPA and other retailers. They generally cost $10 or less. I got mine at NAPA several years ago...it was about $7 or $8 back then.
