JohnTeee Posted October 9, 2011 Report Posted October 9, 2011 Well, I have a new problem, that will probably be 'old' to a lot of you. Having let SpecialD sit as long as it did (around five years), the fuel went bad. I had lacquer in the fuel bowl, so I'm sure it's everywhere else. I've had the car running after adding fuel. Took it for a spin and parked it and now it's running like crap and backfiring. The plugs are sooty black. I've siphoned off all the fuel I can reach that way. Turned the engine over to pump everything out I can get that way (including a little water). Drained the fuel bowl after that. Pulled the top off the carb and sucked out fuel and it did not look bad inside . . . I have no strong inclination to pull the fuel tank and completely drain it, but guess it could be done. <grin> I have a feeling that pouring fresh gas in is going to stir up the remaining fuel and whatever is in it. I have thoughts of adding five gallons and some Gumout Fuel System Cleaner . . . Care to share experience? Thanks! John Quote
oldmopar Posted October 9, 2011 Report Posted October 9, 2011 If the drain plug no longer is usable I remove the tank sending unit and use a electric fuel pump to drain out the tank Quote
Reg Evans Posted October 9, 2011 Report Posted October 9, 2011 Drain out as much as possible and add 1 gallon of Laquer Thinner. Let it sit for a few days and drain. Quote
JohnTeee Posted October 9, 2011 Author Report Posted October 9, 2011 If the drain plug no longer is usable DOH! What a NOOB! I actually have a gas tank that was very clean inside and freshly painted (six or seven years ago) with truck bed material on the outside . . . AND a drain plug that is very easy to get out. Here's the crap that was in there - bottom of the pan IS really pink. Drain out as much as possible and add 1 gallon of Laquer Thinner. Let it sit for a few days and drain. On my way to the farm store for lacquer thinner right after this. Mowing six acres can wait a little bit longer . . . <grin> Thanks guys!!! John Quote
JohnTeee Posted October 11, 2011 Author Report Posted October 11, 2011 Following the helpful suggestions of Reg and oldmopar, I have: *Added a gallon of lacquer thinner and let it sit for two days *Drained the thinner and was it NASTY. About 4 oz of sludge *"Repurposed" the 7 gallons of gas I got from the tank by straining it through 4 layers of paper towel, added it a gallon at a time to the tank, jumped on the bumper a whole lot and drained each gallon out. Gradually decreasing amounts of, what must have been rusty water, and sediment and particles. I'm getting ready to add fresh fuel and the GumOut and see what happens next! Plan to flush the line with some of that fresh fuel to get rid of the rest of the old stuff that may be in the line. Cheers! John Quote
oldmopar Posted October 12, 2011 Report Posted October 12, 2011 If you had a lot of crud in the tank you may want to blow some air into the tank through the gas line to clear the in tank filter. I know the cars had them and I think the trucks also had them if not someone will correct me. Quote
Young Ed Posted October 12, 2011 Report Posted October 12, 2011 Next time try a coffee filter. Works great. Quote
Don Coatney Posted October 12, 2011 Report Posted October 12, 2011 If your tank interior has been painted the addition of laquor thinner may attack the paint. Quote
JohnTeee Posted October 12, 2011 Author Report Posted October 12, 2011 @oldmopar - that's a good suggestion. I have good flow, that might make it better. @Young Ed - does the coffee taste funny afterwards? @Don - Just the exterior, for the bed coating. I think I had posted pics in the old forum of the interior I could see through the sensor opening. A, then current, discussion had been of tank interiors and a lot of guys had BAD rust in tanks. Mine looked pretty good. And, I still have them. Here's a pic of the exterior: And what you can see of the interior: These were something like six or more years ago. Cheers! John Quote

John That's how mine loked exactly after it was coated inside the tank six years ago. Now, the coating is desinigrating. Quote
