How do you remove gas from the tank?

[Cosmic Charlie]

Is there even a simple way to get gas out of the gas tank, without breaking the filler mechanism ?

 

Ya - I see I screwed up the title ... DUH me

Maybe a small ball siphon...

I found if you slip any size tube down the filler neck it hangs up on the spring loaded flapper thingy and breaks it when you try to pull it out ... (?)

Unless there is a way to hold it open when you pull the ball valve back out once the tank is drained...small screw driver? I'd stop at northern and see how small a siphon they offer, they do work well.

Why do you want to do this?

Iike I said - if an emergency came up it would be good to know

(and NO - I'm not a crook)

gas & money are not an issue here

If you unhooked a fuel line somewhere could the electric fuel pump empty the tank?

best old way before DI was to hook a fuel line to the "pressure port" and drain it using a fuel volume hose into a large vassal, engine running at idle no load, works the best with little effort and when fuel pressure dies off it cuts the engine. Always worked for me in the past, but never tried it on DI.

 

I am not a fan of jumping the fuel pump relay for long periods of time.

There is literally no emergency that would warrant doing this. And if it is an emergency there is no way you could remove enough fast enough.

 

Please give us an example of said emergency because it sounds to me like you just want to siphon gas and I doubt anyone around here cares to help with that.

 

* I could have a million or even a billion dollars in a bank and money would still be an issue so you must be JD freaking rockefeller. .

I'll give you a scenario/emergency...Its a personal screw up on my part. In a big hurry last year I had to pull into the gas station so my 13yr old son could use the bathroom. I figured why not top the truck off quick??? Well in my rush I grabbed the green handle (always diesel) and proceeded to put 15 gals in. Turns out I pumped 15 gals of gas into my 2015 Duramax. My son walks out, looks at the pump and say's "Dad, doesn't your truck run on diesel??" NOOOO....Bottom line I had to siphon all of the fuel out of the truck into several waiting gas cans. On the diesel it was easy to use the ball valve as there is no spring loaded flapper in the filler neck like the gas trucks have.

That is not an emergency it is a screw up. No ones life was in danger. Solution there is drop the tank and drain it, No rush. Siphoning was silly as there is no possible way you got it all.

 

Gas does not hurt a diesel like diesel does a gasser, so you were probably ok doing that but the reverse would not be so lucky. Many military vehicles have diesel engines that are converted to run on just about anything from gas to diesel to biofuel to wood grain alcohol.

EMP...............tornado..............hurricane................blizzard..................flood................the last 4 could leave you stranded for days/weeks, and you may need the gas for a generator, chainsaw, snowblower etc. The first example would be the most catastrophic; anything controlled via computer would be toast; and fuel would become a valuable commodity.

That is not an emergency it is a **** up. No ones life was in danger.

True, nobody was in danger other than me being late coming home from ATV'ing with my son..(my wife and I were supposed to be going out that evening)...but it does give credibility to his question, maybe the use of "emergency" was the wrong term.

 

Big ***up on my part by the way! I always look twice at the pump now

I don't know of many 2015 Duramax's with the new emissions that will run for long with 15 gals of unleaded mixed in. I was able to get pretty much all of the fuel out. When I filled the truck back up it took more than the tank was supposed to hold in theory. I'm pretty sure the gas motor would also run on with a half gallon of diesel/gas mix.

If you are worried about any of those things buy yourself a US military auction vehicle and make a doomsday machine. Or just keep a few jerry cans laying around. Problem solved. Buy solar panels for electricity, no need to run a genny in 2016 also get a handsaw & a shovel and you could survive infinitely longer than with 'some gas I managed to siphon out of the truck'.

 

I am literally trying to picture some old crotchety dude in an end of the world situation firing up his snowblower to clear his driveway. "The world may be ending dammit but he who has the cleanest driveway wins!"
