    i was out yesterday driving around and i noticed i was using a lot of gas, and did not know what was going on until i pulled into a parking stall turning left into it and i could smell gas. i thought right away i had a carb problem, but after i looked around i seen a gas trail coming into the stall:mad:
    the thing i need to know is my gas cap vented or not? i will just buy a new nonlocking one. any idea's before i buy a bunch of gas caps?

    thanks wyatt

    are you sure it is your gas cap that is leaking? maYBe check over it a little more before you buy one. (i know on my hijet it is not vented)

    yep it's the gas cap...it's leaking right passed the seal. it just pours out on left turns.

    Mine too.

    I don't fill mine above 3/4 coz it leaks as well.
    Which means I have to buy gas more often - like once every 3 months! :D

    i know what you mean...i filled mine full only twice, once when i picked up and one time i was driving around town and noticed gas coming out when i parked in front of my son's house. so i only fill to about 2/3's or 3/4's but on sunday it was only at half a tank. what was happening was as i turned left the fuel all went to the right side of the tank and passed the cap seal...this never happened before. so i am going to try to find a new seal or just get a new gas cap...this is the reason for the thread. i need to know if the cap is vented or not so i can get the right one. :)
    thanks for the input

    I have not seen a truck yet that had a vented gas cap. I believe all fuel systems on all the trucks(models) imported will be a vacuumed system. Even the Japanese have EPA rules.
    Please correct me if I am wrong.
    On another note, If you have a check engine light on thats on, one of the first thing that needs to be checked is your seal around gas cap. If the seal is bad and sucking air sometimes it will throw a light.

    If it's the same as my zuki it's a non vented cap ;)

    I would say not vented. I know on a hot day when you take cap off my '96 Mits, lots of pressure is released. If it was vented, wouldn't be any pressure released. My opinion.

    sounds like a bad vent. it is probably air trying to get into the tank.

    I have a 94 Minicab with gas cap problems and also wonder what/where a new cap may be had? The foam sealing material rotted and a screw went missing, my guess into the gas tank. I used some inner tube to make a seal replacement but it does not feel right going on. I had the leakage problem earlier until I learned it has to be tightly twisted for a full seal. That was before the foam deteriorated. Help for a part number. Auto Zone was no help.

    I've seen fuel caps on Ebay occasionally foe Mini trucks! You'll have to do some searching!

    I’ve replaced o-rings on several gas caps and got them to seal up again for several years. I had my old Toyota, for 24-years and replaced the o-ring on the cap every couple of years.

    I looked at my assortment of O Rings and didn't think any were as thick as the foam rubber material and certainly not as wide. I am open to any suggestions of substitutes however. The screw replacement was also a very make do as the threads are fine like jewelers threads and I had none that fine....so likely have re-threaded it to stabilize the cap internal parts.
