I have a 940 wagon with 10 gallons of 18 month old gas I want to get out before I run it. I had no luck with assorted size hoses down the filler pipe. Short of opening the tank, any ideas?

 

Crack the fuel pressure rail attach a hose turn the key on and let the pump empty the tank. Hell just burn it!

PRI-G Gas Additive
PRI’s original formula was developed more than 40 years ago for oil refineries in order to keep gasoline and diesel fuel fresh in long-term storage. For more than 15 years PRI products have been used by merchant cruise ships to fix poor quality or stale fuel, allow the use of less expensive lower grade fuels, keep fuel fresh in storage, prevent engine or boiler damage due to carbon matter buildup, improve performance and substantially reduce fuel costs by improving fuel efficiency up to 15 percent. Additional commercial markets that have benefited from PRI include: power plants, cement mix, transit bus, and school bus fleets, commercial diesel fleets, sport fishing vessels, generator service companies, construction companies, and farmers.

Gasoline sold in many states contains 8-10% ethanol. The problem with these “oxygenated” fuels and "low sulfur" diesel fuel is they can begin to go bad within 1 month of being manufactured. Quite often by the time you buy the fuel, it has already begun to go stale. This can result in premature engine failure as well as clogged fuel systems. This is particularly a major problem for backup and standby emergency generators. Furthermore, “oxygenated” fuels are less fuel efficient thus giving a minimum drop in fuel efficiency of 3 percent according to the major oil companies. PRI counteracts all of these negative effects of “oxygenated” and "low sulfur" fuels. In addition to keeping stored fuel fresh for years, PRI will actually restore old fuel.

To save additional money, many customers treat standard grade fuels with PRI instead of buying more expensive premium blends without any loss of performance. Bottom-line PRI products work and the industrial strength concentration with a 2000:1 treatment ratio make it extremely cost effective.

 

Yep, use the fuel pumps. Plumb a long length of line to the return from the fuel rail, run into a jerry can and run engine.
Your lawnmower will burn that fuel.

I agree with just using the fuel. Throw a couple bottles of STP in there and just run it out. Every time you use about 1/4 tank, top the tank off with high octane.
my 240 has two year old gas in it, and it's running strong.

Crack? Where?
Any danger pumping 3 yr old gas through the system?

 

how much gas is in the tank? if its close to full, the old gas will be in better condition than if its nearly empty. but if its nearly empty and you fill it up, you'll have 80% or whatever fresh gas, which should be fine.

LH injection is pretty robust.

going to try this in the next day or two...

do i jump the fuses (to power the fuel pumps)?

where do i attach the discharge hose?
(does anyone have a diagram?)

thx!!

 

I would jackl up the back of the car and put it on stands, then disconnect the fuel line that goes from the tank into the main pump, this is under the car, approximately under the back seat, and forward of the rear axle.... connect the line from the tank to a fuel-safe hose, run this into a large enough barrel, then take OUT the tank pump fuse (fuse 4 on 1985+, fuse 5 on older ones) and jumper the RIGHT fuse terminal to the left side of fuse 6 (which is always powerred even if the car is shut off). this will run JUST the tank pump, so you keep the bad fuel out of your main pump and fuel filter and stuff.

if the tank is full, I suspect it will take an hour or two to pump it out. you may need 16 gallons or more worth of fuel containers if the tank is full. Shut the pump off by removing the jumper wire as soon as it runs empty, you don't want the pump to run dry for long. safely and legally disposing of bad gasoline will not be much fun, you might contact your local toxic waste disposal agency to see what to do with it.
