Ideas to increase half ton fuel range

[dreadinger]

I would think if the auxiliary tank was sealed it wouldn't affect anything. What about vehicles with stock dual tanks?

It was awhile ago on a diesel. I tapped into the return line to the fuel tank, I used an old fashioned switch like on old trucks. I had a toolbox fuel tank setup. When the truck tank ran low I would manually switch on the gravity feed to the return line,fill tank switch off.

Diesels have no vapor emissions like the gas vehicles and have a sensor in the tank so that trick wont work on 1996 and later trucks.

The PCM is programmed for RPO NJ9 for dual tanks and a different parameters for increased capacity on the vapor test.

I can count on one hand in thirty plus years the times I've turned my motor off to refuel.

 

The computer would detect a refueling event and not set a code when the transfer tank dumps fuel into the main tank.

 

Wavian Jerry Cans are the best, blue and red cans in the photos above.  Get the real pour spout, not the government one too.  They're awesome.

 

I never shut my diesel trucks off.

This is my first Chevy gasser...will it throw a code if you refuel with the engine on?

 

I’d rather leave it running with the climate control on...

I often leave my rig running when I'm refueling. That way the wife can have the heater on, and she can continue to watch Frasier / Seinfeld on the in dash DVD system while i'm out filling up the tank, cleaning the windows, checking the trans fluid, etc. 

 

My only concern about externally mounted fuel cans, is the fact that fuel is flammable. If your rig rolls over, there is going to be one hell of a fireball to deal with. Like these guys that have them mounted on the front or rear bumper - what if you hit someone, or you get rear ended? 

 

Here is a fine example:

Another option is the "Rescue" fuel. It is extremely safe, when compare to regular gasoline. 

 

Although it will burn under the right circumstances, it will not explode or create a "flash" fire. It wont even ignite in an engine, unless the engine is hot. If you try to start a cold engine with this stuff, it simply wont run. You have to add it to your fuel tank soon after it runs out of gas, and then make sure to get more gasoline before letting the engine cool. 

 

Its a great product to have on hand. 

 

Might not be what your looking for if your trying to extend your range by hundreds of miles, but it sure is nice to have when your looking at the "Fuel Low" indicator on the dash. Will I make it to the next gas station?

It should not.  Once started, the computer is going to check the fuel level against the time before it was shut off, or something along those lines.

Tank pressure code is only set of the computer senses multiple fails over a period of time. So, you can likely fill tank with engine on. . .
. . . But, cleaning up body parts from all over the station is annoying for the station attendant to clean up [emoji6]

Nonsense.
