I finally worked out the details on the 96 Dodge Caravan which had been sitting for 3+ years, (previous thread "Dodge 3.3 liter V6 hasn’t run…March 29) but still have a question about old fuel. I was unable to get the fuel pump relay out of the socket without more force than I dared, and had no luck siphoning, so couldn’t empty the old fuel. With nothing to lose, I figured I’d try starting it with the old gas in the tank. I got lucky: it started fine and sounded more or less normal.
I now have about 20 miles on the car, tank is just under 1/4 and it sounds and runs well enough.
The question is: should I still find a way to get the tank emptied? Or is good enough to just fill the tank to dilute the three or four gallons of old gas? I’m thinking this is a good time for some injector cleaner, or Berrymans B-12 …not sure if that does the same thing, or if it’s superior in this particular situation. Does anyone have any ideas about how the old gas would influence an emission test?
If I don’t find other major problems with the car, I will eventually pull the tank and replace the fuel pump as a precaution, as ok4450 advised in the previous thread, plus trans service, brakes, alignment, etc. Mileage is about 151k.
I appreciate any advice, thanks very much!
