Second fuel tank besides Bronco II?

[ben_2_go]

Many years ago, probably 25, a guy brought in an '89 with a second gas tank on the passenger side. It was a stock tank turned around and fueled behind the wheel well on the passenger side. He had a switch to chose passenger or driver side tank. It activated relays so the fuel pump in the tank would run and the sending unit would show the right level for the tank that was being used. Has anyone done this on a 98+ truck? I know about the BII tank in the spare tire location. I'd like to get the range up as far as possible so I don't have to carry jerry jugs. I'd also like to keep my spare tire under the bed.

Bo but i say do it. Sounds like a good plan

Only thing is the muffler usually sits where you’re proposing putting the gas tank…

You just run out of real estate under the vehicle

Gas tank is on drivers side, Cat Converters/exhaust on passenger side, trans/drive shaft in the middle
Only place left is where spare tire is at
Or in the bed


EVAP system cost was the demise of the Dual Tanks
EVAP system is an emissions requirement and got expensive after 1990 or so
It used to be a ported vacuum with a charcoal canister, now its alot more stuff, lol
It seals the gas tank and requires a few valves and pressure sensor to work properly, and computer software to maintain/operate it
There is a purge valve, a vent valve, an in tank pressure sensor, a vapor canister and a charcoal canister, and all the wiring
If you don't have to pass inspection then 2nd EVAP system can be eliminated
They can't do that with new vehicles


Dual tank valves are fairly straight forward to install and plumb
The switch in the cab changes tanks AND fuel gauge, also easy to wire up

No cats and muffler will be up forward in their place. Just exhaust pipe to the rear.

Not sure you have looked under your Ranger

Exhaust pipes, with or without cats and mufflers shouldn't be near metal or plastic gas tanks, just a really bad idea, lol

Maybe look at a Side Pipe as an option, exhaust exits just behind front wheel and travels, outside the frame rail, back to exit just in front of rear wheel
That would open up passenger side area opposite of current gas tank, so you could install another 17 or 20gallon tank

It might sound kinda crazy but older trucks had a gas tank behind the seat?

Yeah I been under there so much I quit paying attention so I don't find more problems. I'm looking for a 98+ 4x4 for an overlanding project. I'm supposed to go pick up a Kubota engine, to for a diesel conversion for the overlanding project, this weekend.

Mostly pre 1972 Chevys and Furds.

And the old Willys Jeeps had them under the drivers seat, had to lift seat up to fill tank.

Yep. My CJ3A had the tank under the drivers seat and my CJ5.

They changed the FMVSS title 49 for that obvious safety reason and made it mandatory to not have it in an un-walled passenger compartment, same with batteries, and got rid of gas tanks under the entry door on buses too. Gas tanks now have to be of a pliable metal or substance not prone to cracking in a collision.

Every few years I read the FVMSS for kicks, you can learn a lot about the thought process that goes into the design of such things as dashboards and mirrors. Then every couple of years, someone such as Jeep will re-think something such as the transmission shift lever and depart from the guidelines and industry standards and develop such a fine alternative to transmission shifters. That is causes lots of avoidable accidents from people hitting solid objects such as garage walls because they were in the wrong gear.
