2008 Yaris - Siphoning gas - Toyota Yaris Forums

Looking to siphon some old gas out of my 08 Yaris sedan

Has anyone had any luck siphoning gas from a similar model via the fuel filler pipe?

Does the 08 Yaris have a rollover valve or other blockage that would make it difficult for me to insert a pipe all the way down the fuel filler pipe and into the tank?

Appreciate your help!

Yes, there is an anti-siphon/rollover mechanism in place.

How much old gas is in and how old it actually is? Is it really worth the effort?
If it is not like half a tank of a year old gas, I would probably fill her up with fresh fuel and get on a long highway trip.

It's been sitting since May (about 8 months) with about 3-4 gallons in it (10% ethanol). Definitely tempted to just fill her up with premium and drive off. Worried though about damaging the fuel pump (or worse).. $500 to replace the pump, $500 of which I don't have right now
