Anyone have experience draining old gas out of a tank? My uncles truck has been sitting since 2020?, he put some stabilizer in it, but its still been two years stagnant. I’m not sure how much he has in there, so the old siphon methods might not work the best if he has a full tank.
I looked at a couple electric models but they wanted $100+ and I can see that stubborn old man just firing it up as is before I could see him spending money on a pump he will only use once.

I have that, used it once. It folds up nicely but the legs are a little wide when folded up--GIGGITTY!

Thanks!
I ended up ordering the Jegs version.
(A bit cheaper)

Comparing images on the ads from amazon, Jegs.com, and reviewers' images.
I don't see a difference between the two.

And just now, i get an AD suggestion for the summit racing version!

I picked this one up last year or the year before and have been really happy with it. I returned a Schumacher and got this one instead. The quality of the Schumacher stuff has gone downhill.






I like the footprint and the similar features this one has. What gauge are the wires? Does it work as a trickle charger as well, or primarily designed as a booster?
They might be #4, but more likely #6. Also about 6” long. It’s purely a booster.

I would find out how much fuel you’re dealing with before making any decisions on how to remove it or what to do with it once it’s removed. I siphoned out 12 gallons pretty easy, put it in containers and then transferred it to other vehicles but that was good gas. I removed the fuel filler neck and that made easy access with a hose. How are you planning on disposing of the old gas?

I have a car ('94 Acura Legend) that's been sitting in storage since 2020 as well. I also put in Sta-Bil. Fires right up.

i would say if it starts and runs just drive it, worse case it runs like crap till you add fresh gas, if it's so bad it won't run then do like mark said take the filler tube off and go in that way

Throw some fuel treatment and some octane boost in there and drive it. It'll be fine.

I bet my camaro has some remnants of gas in it from 2015 lol. I juiced it up with treatments and have been putting around after a fresh 1/2 tank of 100% 93. I'm trying to get it down to the low fuel light and fill it up with fresh 100% 93 and run that tank through it.

Finally got the valve cover gaskets replaced at 255,000+ miles. Hopefully that will stop the small drips onto the headers. Deep cleaned the interior and cleaned the engine bay pretty well last weekend after playing in the dirt for three weeks but I'm giving up on the exterior until it quits raining and/or warms up a bit.
