Draining The Gas Tank

HOWDY PEOPLE!

CAN YOU GUYS TELL ME THE EASIEST AND BEST WAY TO GET RID OF THE OLD GAS IN MY TANK?

I STUCK A SIPHON DOWN THERE AND CAME UP DRY! NOT SURE HOW THIS COULD BE, EVAPORATION? I DON'T REMEMBER HOW MUCH FUEL WAS IN IT.

ANYWAY...THANKS FOR THE HELP.

Was the cap off the tank for a long while? I've seen cars with no caps have zero fuel in the tank. You can try removing the sending unit to look inside the tank.

Drill a hole in the bottom, that's the easiest way Use a flashlight and look in there, it isn't unreasonable that it is empty

But now that Im starting to get it back on the road I need to take care of things like charging the battery changing a lot of the rubber (like radiator hoses and such) AS WELL AS SUMP THE TANK! Other then trying to siphon it out. Is that any way to easily remove the tank OR is there a drain plug!?

Does the gauge show anything?

I imagine you could remove the fuel filter, turn the key once to "prime" the system...that would start the fuel flowing out the line and keep it going (because you started a siphon). Maybe?

Did you have the cap on? Just run the car. I have let my car sit for long periods of time with no ill effects. The LS swap the car sat for 9 months and I did nothing to the tank or gas before starting.

best way to find out without putting old fuel in the system is to remove the sending unit and look inside.

If it is completely dried-- you might consider changing the in tank filter, inline filter and having the injectors professionally cleaned..

When I bought my 85 the fuel tank had about 5 gallons of water in it. I think it was an upset girlfriend or something along those lines. With the sending unit removed, I was able to siphon out most of the water/fuel in the tank. I was then able to get my arm inside with clean rags to get the rest. I let mine sit open for a few days to let everything evaporate. Lastly I used an air siphon to get the pesky little pieces in the corners.

Another alternative would be to jack the car up, remove the fuel filter and drain it from there. Shouldn't be anything left in there after that.

Okay..

I Started By Taking Raids Advice! I Drilled About 5 Small Holes In The Tank! And Nothing Came Out!!
Your Full Of Crap Raid!!

I Will Probably Take The Pump Out And Inspect It. This Car Has Been Sitting Since 03. The Cap Was On The Whole Time. But I Need To Be Sure.

I Need To Buy A Battery And Purge The Line And Put The New Fuel Filter In.

Thanks Guys.
