LB7 Winter Storage

I know this question must have been answered at some time in the past but what should a person do to properly store a truck for 4-5 months?

Also I have read a lot about different fuel filter systems for these trucks
I know some filter fuel well but not water and vise verse, and when you filter for fuel and water with two sepaerate units you are putting a lot of strain on the injector pump.
What is the best solution on a low budget?

the factory filter is perfect if you keep a clean one on it and dont use any additives that are emulsifiers (suspend water in fuel like alcohol) you need a demulsifier that removes water in suspension in the fuel so the filter can remove it. also ulsd is low on lubricant so an additive may prove useful to help pistons in the pump and injectors, but water is the main culprit that causes corrossion. of course change oil to remove contaminats from crankcase, add a fuel stabalizer and run truck some over the winter to keep everthing lubed, and use a battery maintainer to save those expensive batteries.

What I did to store my truck while I was in korea was
1. Fill tank and I put stanadyne in the fuel
2. disconnected the batteries
3. Put up on jack stands

I went back home after almost 7 months, hooked up the batteries and the truck never skipped a beat. I had been using stanadyne in every tank prior to the storage too.

As far as filtration, I have been running a racor pre-oem filter with heater and water separator for a good portion of the time I have owned my truck. I recently added the cat adapter to the stock location. I wanted to make sure that I was filtering the fuel the best I could. I think there has been at least 3 revisions to the GM filter up until this point. It has gotten better, but I still don't trust it. That is why I went aftermarket for filtration. It is piece of mind for me.

Sounds like you have it under control and the stanadyne is a good additive. Should have no problems with your approach.
