[Vwdiesel] Tank Slime

[Willard561]

Dave,
I let my Rabbit sit for about the same amount of time as you did, when I got it running I had issues like yours, I tried to suck furl throw the filter & no luck, replaced the fuel filter still no go. I pulled the access of the tank and it didn't smell like diesel any more.I pulled the filter screen in the tank and it was sludged up solid..If it'd been a pickup emptying the tank I'd have taken it to the quarter in the slot car wash & cleaned it real good. How ever I have a 4 door so dropping the tank is a big pain. After draining the tank & wiped it out as good as I could, I cleaned the filter screen, and ran the old fuel through some of the see through filters you can use with a gas engine. Then I went to a truck stop & bought a jug of fuel treatment that's designed for fighting "Diesel Sludge" I put the recommend amount for a shock treatment in the fuel when I poured it back into the tank and used the maintenance dose of the stuff for a year after. So far no more problems, but I don't let the car sit any more either.

PS if any one in the Northwest Oregon or Southwest Washington are needs it I have most of a gallon jug of the fuel treatment left

"Hi all,

    A week or so ago I asked for Hagars no gauge tuning advice for an old diesel 
Rabbit that I wanted to bring out of retirement. I got it started, it idled 
nice, I took it for a little ride and then shut it off, and started over and 
over again fine. The next day I tried starting it and it didn't want to start 
again. I got it started that  first time though, by filling the pump with diesel 
purge and spraying wd40 in the intake.  
   The car sat for about 3 and a half years and the old fuel has just sat in the 
tank all that time. I am wondering if that old fuel is the problem. Do I have to 
drain it or is there an additive that I can add.

Thanks,

Dave"
