Ok, when my car blew up in August 2005, i drained the tank of the contaminated diesl/gas mix. i wiped down the entire inside of the tank and changed the fuel filter. I put in about 3 gallons of good fresh gas in at that time. The car ran for <2 min, before the motor hydrolocked and blew up. The car then sat till march '06 untouched. i finally got the engine out, and the fuel lines were left open.

... fast forward to the present...

I am getting close to firing up the new engine, but im thinking about that gas in the tank. it was about 3 gallons back then but due to evaporation i figure there is around 2 maybe left in it. maybe it doesnt evaporate that much but maybe with the fuel lines open? anyways, i got a siphon setup today and did my best, i pulled 1.5-2 gallons out of the tank when the siphon stopped pulling anything out. so at most i have a gallon or so still left in the tank. It was BP 93 octane. How bad is that to leave whats left? Of course I'm going to get at least 5 gallons of fresh gas and pour it in before i try to start it. hopefully thatll dilute it enough.. I just really dont feel like dropping the exhaust and pulling the tank all over again over 1 gallon....

advice?
