Siphoning out 2 year old fuel on my 93 Z? Ok, so as of now I got 5 gallons of close to 2 year old 110 octane fuel in my tank. The tuning is set up to completely disable knock retard and the motor has about 30 mins of run time on it total. I'd like to siphon this crap fuel out and put in new stuff, but i've heard that newer cars got a baffle that prevents you from just sticking a tube down into the tank to siphon out the fuel.. Is this true? If it is, how do I go about getting this fuel out of the tank? Also if there is a baffle in keeping me from siphoning the fuel out could I at this point just put in some fuel stabilizer in and then this summer just mix in another 5 gallons of 110 octane and run it like that? (It actually only needs 93 oct. fuel, I just put in 110 oct. right after the initial cam break in)

Yeah the gas in my tank is older than hell and my car is almost back together so I was wanting to do the same thing....but with it flowing through the pump, i've heard that it can ruin the pump..is this true?

I would change your fuel filter after you do this.
