Spare parts storage question

As I have gotten older and become financially able, I've made it a habit of buying two of something when I need a replacement part. There's always a seal blowout on the combine on a Saturday night it seems, and my parts stashes have come in handy.

I noticed the other day that the adjustable fuel pressure regulator on one of the old trucks had a drip to it (after I made an adjustment to it, of course). I got on the Holley website to order one and ordered two out of habit. Two trucks use those and they are about the same age. If one failed the other might also. They are a typical accelerator pump style diaphragm - two metal disks with a "rubber" flexible seal sandwiched in between.

My question is this: where do I put so that it might still be pliable if it is a couple of years before I need it? It would usually go in the bin that holds the mechanical fuel pumps and carb kits, but that's in the unheated machine shed. I hate to separate parts, but would it be better off under the kitchen sink out of severe temperature swings while it is dry? I can't say as I have had a carb kit or diaphragm that I have purchased and waited more than about a month to use in the past. Who knows, I may have wasted $6 buying an extra, but I'll be more than $6 happier if the other one ever leaks. Providing I keep my spare pliable and it isn't dry rotted and stiff when I need it.

So where should I keep it? Put anything on it?

Well, if the other might go out, maybe just change it now. Solves 3 problems. 1 storage, 2 having the other fail 3 having to fix it when it isn't convenient to fix.

Or put it in a labeled plastic bag and store it in the parts file cabinet used for indexed small parts. Jim

I would think sealed in a tightly closed jar with a rubber sealed lid, in the dark, away from heat would be about as good as any. Cold shouldn't be a problem, but heat is.

The jar would prevent the exchange of gasses that promote loss of solvents in rubber. Also keep out insects, rodents.

A jar would also keep it visible so it could be found.

We eat lots of peanut butter. Have many many clear PB plastic "jars" that are so usable. Write on the tops with majic marker.

I use a lot of the small plastic storage containers. They stack well and you can see what's inside them.

The Holley Regulators have a rebuild kit(diaphragm & 2 springs.one for hi-pressure and one for lo).be cheaper & quicker than changing out the regulator!!!!!!!!!!!!!!!!!!

I thought I put that in there but I guess I missed it - the kits were what I ordered. I was glad they had both springs as I had acccidentally ordered a high pressure one for one truck and fought leaks at all of the hose clamps. Now they can both be low!

I use medium sized totes and label them according to the table of contents in the JD Parts Manuals plus a few other categories I have come up with.
