Keeping my bladders full

I thought I read somewhere here that it is wise to keep the fuel bladders full to extend the life of them. Is it OK if they are almost empty for a few weeks? I am having a hell of a time getting fuel in my aircraft. The airport won't refill the aircraft unless it is outside of the hanger, I can't pull my aircraft out of my hanger due to the ice. I ordered chains for my powertow but I was shipped the wrong size.

Typical advice for fuel tanks is too keep them full.  Most often this is to keep the surfaces from getting really hot in the summer and breaking down.

Kept indoors for too long people get concerned about corrosion.  Still not a problem for you this time of year.

bugs and rodents? Same issue.

I don't have any real bladder advice to share...

Bes regards,

+1  As long as you have some fuel they are good.  They are not going dry out in the hangar in winter.

Thank you very much. I thought it was an issue of drying out and cracking. Well this buys me time to haggle with the tire chain vendor to replace the wrong sized chain. I'm so pissed at the manufacturer as I think the moron at the factory dumped in the wrong chains. Must have been packaged on a Friday.

Sounds like an OWT. Absent some input from a the RubberMaid herself I would not sweat it. I've heard this advice but never from O&N.

FWIW, I've heard the same advice re wet wing systems. This makes more sense but I doubt even there it means full, more likely not empty.

I got the same note with the the bladders.  I think Anthony hit it on the head.  Outdoors, the heating can cause possible shrinking, drying and cracking. I think that this would apply even more to wet wings, they often leak when full.  The PRC dries out faster with heating.  An additional consideration could be liability of condensation causing water in the tanks.  I think this is a lesser issue.
