How to drain fuel tank?

[achilles99]

Just picked up a Roush supercharger kit, and need to drain the fuel (already installed supercharger). Is there an easy way to do it? I believe there is an anti-siphon device/screen that would prevent a hose from getting into the tank.

Do you have regular in there now? How much?

The skinny pedal on the right, step on it...

3/4 tank of regular, supercharger requires premium or it voids warranty. Unless Vanilla is willing to cover it.

drive it as much as possible before install, fill with premium and mix. I this gasbuddy.com will list octane rating s in your area. We can get race gas at certain pumps.

Use a gallon, add more premium.

never mind, saw you already installed it. Just drive and fill. Should've put premium in before you got it installed.

Can't you add an octane boost to the fuel already. Should be a way to prime the fuel line as well.

Running some lower octane fuel for a bit won't kill it. But agree that the octane busy is a good idea.
Best buy extra. Some gas stations only carry low grade, and if your traveling and need fuel, you'll be stuck using it.

You can run lower grade fuel just dont push it hard, amd keep your revs low. No flooring it, and be sure to listen for any knocking. It would be best to drain, but i would atleast add octane booster, and follow my advice. Best of luck

Use a siphon hose to empty the tank.
Disconnect the discharge line from the pump, attach a hose to a gas can and turn on the ignition.

No, i'm saying go out and drive it, run out of gas and push it home.
