I was doing some research and wondering if anyone did a good 2nd gas tank. I did a search on some other forums and all of them were not for 4wd. I looked at the 87 ranger and they optioned a 13 gallon tank behind the axle and I have found used ones for as cheep as 35 clams. Do you guys think its a good idea? I hate having to think about draggin jerry cans in the bed because I want to sleep there under my cap or my bed tent. I am worried about my ascent/descent angles. This would be so nice though. Discuss and tell me if its a good idea. Thanks guys............

 

I would be pretty worried about the decent angle on your truck. Unless you have a pretty thick skid plate there. It also hangs down pretty low. Youc an check the ones from a B2, they go where our spare tire is IIRC.

I would not reccomend it, but you can do it. it can't be all that hard. You just have to connect them some how.

 

the b2 gas tank is a 20 gallon. I have seen those on rangers. But the 13 gallon is a little higher and tighter which is why i am wondering though, ya know?

 

You can run into OBDII problems with dual tanks. There are evap leak and misfire monitors that don't work well with them. Notice that Ford's remaining dual tank setups disappeared right around 1996 when OBDII came in.

Even if you could get around that, you would need a second high-pressure fuel pump unit in the additional tank, new wiring and a switch to select the pumps ($$$).

 

I was thinking of just having a transfer pump to my main tank like the land rover guys do. There is an article of how to do the transfer pump on D-90.com When the first tank gets low you hit the switch and let your truck fill up to a pre-designated mark (say the 3/4 full mark) and then you shut the pump off. Some guys bring in the fuel through a t splice on the evap line of the main tank.

 

get a roof rack and put yourjerry cans in that, save yourself money and trouble

 

You'll need a vent between the tanks if you're pumping liquid from one to the other. That could present a problem because the evap leak check monitor is set up for a specific volume tank. When you connect the two, you will increase that volume dramatically. Then the applied vacuum probably won't be able to draw the larger volume down fast enough to satisfy the calibrated time limit and that will light the CEL.

Also the second tank would have to be perfectly sealed. The evap leak monitor is set up to detect any leak that is the equivalent to a 0.020" hole in the system. A leak of that size or larger will also light the CEL.

Don't get me wrong. I think it's a cool idea but I also think it will come back to bite you later.

 

Kinda depressing news. I too was interested in adding a second tank. So Bob, is there any feasible way to set up an aux tank?

 

I think that the completely separate tank with its own high pressure EFI pump might work. I strongly suspect that finding an aux tank that would accept that pump unit would be difficult or would require some fabrication - I don't know for sure. If you can find a way to do it and keep the evap volumes separate, you might be able to avoid the problems with the evap leak monitor.

You would need to avoid running out of fuel on one tank before switching to the other, though. Running out can trigger a misfire code and that's why there are no Ford OBDII trucks using dual tanks today. Ford just doesn't want the unnecessary OBDII warranty cost.

 

Well, thanks man. I am glad I got the information before I got my welder out. I will do some more research and see if there is not another feasible(sp) way to do something of this type.

 

Well if you can somehow figure something up, keep us posted.

 

I will, because I have been dying to free up bed space from the jerry cans.

 

Where are you going that a 19.5 gallon tank is insuffecient?

 

bronco II tank is a 23 gal tank

ive got one waiting to be installed on my truck to repace the stock 16ish tank

 

Well, Michigans upper penninsula is kinda remote and I have had to turn around because of lack of gas when going into the deep woods. I want to be able to go back there and not have to worry about it. Does that 23 gallon work well under the ranger? Do you lose clearence?

 

if put on a stock truck, it will hang wayyyy to far below the frame rails

 

You have no new info for the second tank? I found a place through my brothers work (broncograveyard) that makes custom gas tanks for any vehicle. They do military ones and they also pressure test with your choice of plastic or metal. Right now I think that is my best option.

 

Tell us how it turns out. I would like a custom tank if it doesn't cost a black land farm and my 1st born!

 

Old thread alert! The thread is 5 months old. GroundAssault hasn't been on since November and he doesn't have the Ranger anymore.

 

Thats what I was going to say. I have seen tanks mounted in the bed like a tool box. I think camping world installs aux gas tanks, give them a call and see what they say.

 

not a bad idea, but im sure im not the only one taht goes through low trees..
