TMA62 Posted June 21, 2014 Report Share Posted June 21, 2014 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!

brad Posted June 21, 2014 Report Share Posted June 21, 2014 You shouldn't have to have a vented cap, since the tank itself is vented. Link to comment Share on other sites More sharing options...
Gunslinger Posted June 21, 2014 Report Share Posted June 21, 2014 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. Link to comment Share on other sites More sharing options...
