Are AC o-rings fuel resistant?

[johnathan1]

Hello!

I need to replace an o-ring in my Porsche's fuel system...and I was just wondering if I could use an o-ring from my AC system pack of O-rings. It will fit fine, but I'm just not sure if the o-rings designed for use in an AC system will hold up to gasoline. Anyone know? Thanks.

I'd sit one in a cup of fuel for a day or so and see if it swells up at all.

i<m pretty damn sure they are!! if they resist the oil and refridgerant gases in a<c system, gasoline shouldnt be a problem!
i wondered the same question some time back, when installing my fpr. i was told it would be no problem.
