My Mk5 Jetta has been stored now for three years.
I'm pretty sure I should drain the fuel tank and add fresh Diesel fuel. Are there other locations in the fuel system that must be drained, or are the volumes so small that they aren't harmful such as in the fuel pump(s) or injectors? Should I open a fitting and flush somehow with fresh fuel? Any suggestions?
In order to try to prevent problems on start-up, what else should I do in preparation to re-commission the vehicle?
I'm definitely willing to do some work here to avoid more and bigger work later!
Thanks in advance....
Joe

Thanks so much to both of you for your advice.
I took the battery out a long time ago and put it on a battery tender and it may be still ok. We'll see. It's a small expense compared to the benefit if I get this car rolling and fairly reliable.
The fuel is at about 1/2 full and I didn't know about adding stabilizers so I'll pump it out and take it to recycle.
... don't want to lose prime though. so I'll add 5 gallons and follow the advice above.
Anything else?
Thanks,
