Anybody done it ? Any suggestions ?

 

do you wnat your second on the passenger side or to take your existing on and put it over there...??

to make it simple your exhaust would be in the way unless you get a really small tank, or you somehow move your muffler....

 

there was an early year ranger that came with a dual tank, goes where the spare tires is, and its possible to find one in the junkyard and get it installed on a newer ranger

ill find the post about it on RPS

you should be able to fab that up with a standard gas tank, problem with putting a matching tank on the opposite side is that your driveshaft is offcentered and your exhaust goes right where the tank would

 

You really only have 2 options.. put one back where the spare tire is or
get one that goes in the bed.
Passenger side has too much crap on it.. exhaust etc.

Any Ranger with a factory PCM calibration running OBDII (95+ Ranger) will have problems with any dual tank setup. The evap leak monitor and/or the misfire monitor will flag problems. Notice that Ford eliminated most if not all dual tank vehicles about the time of the OBDII phase-in (1995~96).

 

Thanks , not one of the better ideas I take it

 

So lets say you mounted the aux tank in the spare tire space and used the pump in that aux tank to transfer gas to the main tank when needed. If the aux tank held pressure/vacuum just like the main tank and the vents on both tanks were tied together...would there still be issues with the evaporative system? That may be too much of a simplification, or just totally wrong...but the basic idea I'm thinking is make it just seem like one large tank to the evaporative system. Would the volume difference really be an issue since the air volume in the tank is variable anyway as fuel is consumed? I know you would need to address other issues, like not over filling the main tank...I'm just wondering about the PCM issues Bob brought up. How does the PCM decide to flag those two problems? Is there a difference between how the 95-98 and 98+ Rangers would react since the pre-98 tanks don't have a fuel tank pressure sensor?

EDIT: Or would making the tanks switchable like is usually done be a better idea? Which configuration would offer the least number of problems?
