Does a '79 gas tank have a bladder?

If so, do I have to worry about condensation and rust in the tank?
 
Thanks in advance for any input.

Yes, it does have a bladder. But I would think that unless the badder deforms, condensation shouldn't be a problem.

Kevin, unfortunately from 78-82 the tanks did use a bladder. If you are interested, you can buy a new tank that doesn't have the bladder. They're 18 ga. rust resistant steel.

Thanks guys.
With winter storage just around the corner I'm debating how important it is to completely fill the gas tank.
I always have in the past but my concern is with this newer gasoline going bad in shorter time periods.
(In the past I start the winter with a completely full gas tank. I start the engine about every ten days or so and run it for 20 minutes all winter long.)

Kevin, if you put StaBil into the tank and keep starting the engine it will be fine. There are differing theories on whether to fill or leave partially filled, so in the spring you can add some of  the new season's fresh gas. In your case, you'll need some fresh fuel to replace what you used during the winter. Fuel is blended differently for the different seasons.

The bladder isn't a bad thing. It's like having a fuel cell inside a steel liner. Mine was in great shape!!Thumbs Up

I think the higher levels of ethanol in the fuels today, and the increased amounts that are coming, are gonna play havoc on the bladders in the Shark fuel tanks. They already have issues with them deforming....I believe the ethanol is gonna make that even worse.
Adding some sort of fuel stabilizer is a good idea, but I would add it at the fuel station, and then drive the car a few miles to really mix it in the tank, as well as all thru the fuel system.  At this point, I don't think it will matter if the tank is full or half full....between the water in the fuel to start with, and normal condensation, the tank is gonna have water in it anyway. The fuel stabilizer is the best insurance for that. Thumbs Up

Sounds like some water in the tank can't be avoided. I'll go ahead and use the Sta-Bil fuel stabilizer and hope the bladder holds up.
Thanks for the help.
Kevin

If the tank is full, then there is less air in the tank and it's the moisture in the air that condenses into water. You should also put in the additive.

I always top mine off and add stabil at the pump, about 5 mile drive home.
Interesting that my purist vete mechanic always told me to shut it off and not to start it till spring. As all that cold then heat then cold creates moisture thru out engine, drive train, and exhaust. I disconnect battery, cover it and thats it. doing it the same way for over 30 years.
This year I did invest in a car bag.

Ed Zachary....if you DO start the car while in storage, you really need to let it run until it gets up to full operating temp, and just let it run a while. This will lessen the chance of moisture forming inside the engine/trans/exhaust, and what moisture there is will be "burned" off. Of course, around here, we don't have the extreme cold temps and moisture(usually..but the past couple of years has been weird), so we don't have the same moisture issues as youse Yankee fellers(and fellettes) have.
