HELP! Draining fuel tank - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Just got my injectors in, I have a tune set up for this Friday to convert from 91oct to ethanol fuel. I have about 2-3 gallons of 91+torco in my tank right now, what ways can I go about draining the tank that way I will be putting 100% of the ethanol based fuel in.

I've read different post in the SS section but did not know if the process was similar in the ZL1

Thanks in advance!

I'll tell ya how, Brah: you go out to a deserted stretch of road and stomp that go pedal down and don't let up! It always drains my tank!

Lol I wish that was an option, but with the new injectors my car won't idle very well don't want to put any stress on the motor if it can't even idle..

The one idea I have is to disconnect the fuel rail feed line(in the engine bay), turn the key onto accessory and let the fuel pump out the line into a bottle/jugg etc

That's how we did it. Takes a while but it works.

Thats what I would do. Good luck!

Update: got all the fuel out doing the method I mentioned above. It does take a very long time and helps if you have another person helping you, everytime you turn the key into accessory mode it primes the line with fuel (about 1 pint at a time) I had to repeat the process until the car was out of gas and the line was empty.. I'm a happy camper now and ready for tuning on Friday
