Tigerstop anti siphon valve

Miata Member Posts: 12
I am receiving the anti siphon valve to install on the top of my outside Roth tank soon. It is capable of operating with up to a  13 foot head. The instructions say it operates in air temperatures as low as -14F but fuel temperature only as low as 32F. The concern seems to be the gelling of fuel could clog the valve. I currently add HOT to the oil before delivery and have experienced 15F with no problems so far. Has anyone used the tigerstop on an outside tank and if so were there problems ?

    I have not used this device. So I have not experienced any problems with it. I find that when you don't use most things, you very rarely have problems with them.
