To drain or not to drain, that is the question
I'll be starting work the on the 220d today. The fuel has been in the tank for three years. The volume is unknown at this point. Ideally, I'd like to drain the fuel if possible. Does this car's fuel tank have a drain plug somewhere or should i just find a different way of doing it?
I appreciate your advice! -Ben |

Actually my advice would be to not drain it unless you suspect it is contaminated. Diesel fuel can easily last 3 years without significant degradation. If it was stored someplace very warm you might have fungus in it though. If you do decide to drain it you can remove the tank screen at the bottom of the tank and clean it out too which is a good thing to do.

There is no way I would NOT drain that stuff out before proceeding...
Here is the easy way to do it...if you have air pressure available.. get a good sized hose which will reach from the bottom of the tank up and out through the filler nozzle... and then down to the catch can... suggest five gallon plastic cans... Put the hose in.... wrap around it with a cloth and stick the air nozzle in and block the air escape.... as soon as it starts you can stop the air and it will continue to flow... and may bring up some UGLY stuff ... then when you pull the bottom to clean the lower tank filter you will not have too much fuel running down your arm. Now, not to waste it... if it still is good.... strain it and put it back into your car and burn it a few gallons at a time mixed with good new fuel.

I'd burn it not drain it. People on here have used fuel much older than that. What is three additional years going to do to a fuel which is already millions of years old.

Startron Diesel Additive- http://www.westmarine.com/webapp/wcs/stores/servlet/producte/10001/-1/10001/141656/377%20710/0/diesel/Primary%20Search/mode%20matchallpartial/0/0?N=377%20710&Ne=0&Ntt=diesel&Ntk=Primary%20Search&Ntx=mode%20matchallpartial&Nao=0&Ns=0&keyword=diesel&isLTokenURL=true&storeNum=6&subdeptNum=169&classNum=764
I had a bad case of what I thought was algae in my 85SD. The engine would crank but not start & tank was nearly full. First I changed filters. Glow plug system tested good. Still no start. I dumped Startron in & let it sit until the weekend when I had more time to work on it. Cranked it & rattle, rattle rattle just like normal. At least try to start it before you go to the trouble of draining. Diagnose if you have a problem. These cars have a reputation as bullet proof for a reason. |
