How to drain the tank completely

How to drain the tank completely
Long story short, I filled up with gas the other day and 10 miles later I get CEL P0133 and P0153. All signs point to contaminated gas.
To be on the safe side, I want to drain the tank completely. I have done searches on this forum and see where people recommend using the fuel pump and draining from the fuel rail, but that still leaves a few gallons in the tank. If its contaminated with water, have i really removed the contamination since it will be in the bottom of the tank?
Any other recommendations?

I personally doubt it's the gas. I see stories about it on various forums and all I know is that I've been driving for over 50 years in all parts of the country and have never had bad gas. That's not to say I never thought it was a possibility when a driveability issue arose, its just that the problem always turned out to be something else.

While I have no way to know whether you got bad gas or not, those two codes are VERY common on cars with LT headers which your profile indicates you have. Do a search on "p0133 P0153" and you will find many dozens of threads on that subject. Only 100% solution is to get them programmed out. Details of that are in the posts you will see when you do the search......
Exhaust leak - i have no leaks
Bad 02 sensors - i find it suspect that both 02 sensors failed at the same time
Contaminated fuel - i find it weird that it ran like a raped ape up until the time I refueled, drove 10 miles and it starting running considerably worse, and then the CEL
This thread was very detailed and it didnt mention LT headers as the cause.
I havent came across any threads where just the LT headers cause the problem. I will continue to look, but I have ran the LT headers for 3 months now with not one single issue? Wouldn't that issue be almost immediate?
The only thing I have done recently is a mail order tune from ECS. Would that have triggered the 02 issues/CEL?

If it was a problem, the station should pay/reimburse your repairs.

I did go back to the station and file an incident report. Their Risk Management people called me back and said after a brief investigation, there were no other claims and they have had no issues with water. I have a claim number, but that's about it. i just wanted to have it on record in the event something else happens.
So here is the timeline for mods:
Mail order tune ~ Jan 25th, 150 miles ago, numerous 10-20 mile trips
LT Headers ~ Nov 20th, 700 miles ago, still using stock 02 sensors
New plugs and wires with the headers
And the timeline for the CEL's:
Drove it like a rented mule to try out the new DR's
drove 10 mins normal to fill up
after fill up drove to work ~3 mins
Set for a few hours, started up and drove to town - 10 mins freeway
noticed rough idle in town
drove around town ~ 10 mins
got back on the freeway, CEL came on
drove for another 10 mins on freeway home
What do you experts think? Is it just wishful thinking on my part that the CEL is from contaminated gas? Why didnt I have issues immediately after installing the headers or the tune from ECS?
***EDIT***My battery is also failing. I will be replacing it this week, I have to jump start nearly every time I get in it now.

Will change the battery first before any further troubleshooting. Thanks everyone.
And sorry, 8Vette7, didnt mean to come off rude. The engineer in me makes me overly inquisitive is all.

My engine is heavily modified and I pop O2 sensor warnings on rare occasions where I start it up cold and drive it a little too "briskly" without a couple of minutes of proper warm up. This is fairly common with LT headers & tune, as it tends to make the engine run a little leaner.

Fix battery issues first before any other steps. Failing/discharged battery can cause all kinds of strange issues. LDCM, RDCM, EBCM codes just to name a few. Also advise recharging a badly run down battery with it disconnected from car's electrical.
