Fat Katz Non Vented Pop Up Gas Cap

fatkatzpopupgascapWhat is the remedy to some pop-up gas caps leaking gas by the vent? Simply, a non vented gas cap to use with a vented gas tank.

Fat Katz, a leader in custom gas tanks and fenders, like many builders and owners of their custom built bikes, decided that it was time to end the problem of fuel and fumes escaping through the gas cap vent and ruining many paint jobs.  So, the safe approach would be to order you custom gas tank from Fat Katz as vented and to ask them to weld their own proprietary non-ventedpop-up gas cap. The cap top is stainless steel so it can be polished or painted. It is available with a steel or aluminum bung. Retail price is $200.00. Fat Katz.  or call 877-432-8528

    Don’t understand the issue here…I have 2 radical customs that I have built using Pop-up gas caps that do not leak while riding or parked and they are vented!

    However, I will state that they are more for show than anything else, PERIOD! If you paint the bung to match as I have, you must use extreme caution when removing/installing the pop-up cap and inserting/removing the pump nozzle to prevent/minimize damage to the painted bung. If you ride like I do, then by all means use another style of gas cap that is conducive to filling your tank especially after a few beers…wink wink.

    As my good friend says “My $.02 Cents”.

    Boss,

    I have had a few problems with gas vapor leaking from the cap and getting under the paint around the cap ….. it friggin sucks because it always seems to happen on the big dollar paint jobs and not on the base coat/clear coat, easy to repair, paint jobs.

    Don has used this system on his gas tanks for some time now and I have never had a paint issue when using his tanks with this cap.

    My name is Jeff Nicklus and I approve this message!

    Over & Out,

    Jeff

    Pay me,
    Pretty sure Hotch licenses the use of that. Ain’t too much different than the old Carlini one too.
