So, how important is fresh fuel?
Does it not deteriorate over time? How long can a tank be left in there and still perform?
In our humid climate, we have issues with algae also.
If diesel remains in the tank for a year, with just incremental amounts added a couple times during that year, what kind of issues will that cause?
Are some of the additives ok to use? keep the cetane up, prevent algae, remove water, etc.

I use Power Service Diesel Fuel Supplement +Cetane Boost.

Was confident enough today to disasssemble the fuel line system. Now, I have some questions about how pumps, valves and flow work.

Should I be able to blow air, like blowing a kid's balloon, in th direction of fuel flow?
