  • Fill Valve?


    I've got a 2000 Ford Crown Vic dedicated CNG and recently had the fill valve replaced at a shop.

    Now, whenever I return to the car after it's parked for at least 5 or 6 hours, the passenger compartment has a strong odor of CNG.

    The shop owner said there is no way the parts he installed could cause the odor. I'm frankly upset with this answer as I've never had it smell like this before. He said he'd look at it in a week or 10 days, but tracing these leaks is extremely expensive.

    Meanwhile, I've been turning the quarter turn shut off valve on the driver's side frame rail and cracking the windows open whenever I park. Is that a good practice, or is there something else I can do to keep this as safe as possible?

    I'm going to try the soapy water trick on the back side of fill valve, which I can see looking up underneath the fender. Any one have any ideas or input?

    Thanks in advance for any advice!

    Another possibility is to use a sniffer, or bubbles in conjunction with a sniffer.
