Dual tanks, Thoughts & Ideas
 

So i have an idea for my ranger to increase the driving range between refueling. I was wanting to add a second tank where the spare tire is. don't know what will fit yet. but i didn't want to cut another hole in my bed side so i was going to connect the two tanks (stock and new one) with two hoses. One at the bottom to transfer fuel back and fourth, and one at the top to allow movement of fumes between tanks so they will both empty equally and fill equally. Just an idea right now, has anyone done this before? and if so do they know what fits between the frame rails? Thanks guys!

back in the 80's on the first gens this was an option thats why the fleet side bed floor still has the notch in the bed floor for the filler neck..

you could graft in a gas door and do it..

Hey Zach if u did the best tank would be a Bronco's right? Not saying i'm gonan do it but would that be the best way?

i think the tank will rub the shaft.

personally driving 300 miles with no stopping is usually unheard of when traveling. just fill up then

its mainly for off road, cuz when i hit the dunes i get like 8 mpg, and why not have a bigger capacity? I would fill up like twice a month this way

depending on the size of the gas tank i might have to move a cross member forward, no big deal, so the 80's rangers and broncos should fit or has the frame been changed since then?

why not just put a fuel cell in the bed? i think the simplicity and the lack of custom work would out weigh the 2nd under the bed.

i like bed space cuz i haul snowmobiles and dirt bikes depending on the year which is why i don't have a tool box. i need the bed space and fuel cells are kinda pricey.

maybe you could figuerw out a way just to replace the stock tank with a larger one. There is plenty of rum up there for a bigger tank

well i'm pretty sure that off the F series with dual tanks they are all 16gal which is all fine and dandy but so is mine. or am I wrong?

get one off like an F-250, just go up to someone that decided it would be a bright idea to buy a V-10 3/4 ton truck, tell them they fail at life and that you will take their gas tank off their hands for free.. your doing them a favor

that should be big enough. i hope

wouldnt the check engine light come one if you added another tank? It has a vacuum in the tank and if you loose that vacuum then it thinks there is a leak or the gas cap isnt on etc.. At least that is how I understand it.

well as for the fuel cap light, as long as the other tank is completely sealed it will pull the vacuum, i could even "T" the line and run it to the other tank too.

lol my auto shop at college had one of those as a mock up car.... they might wonder where it went though ha ha

Call me stupid but wouldn't that get you less MPG with all the extra weight?

maybe a little but its all within the truck and not hanging out in the open, you'd lose power especially when they are full. it would just be like having something in the bed of your truck. so i don't really know how much you would lose

OK Yeah that was my thought. Another 15 gallon tank or something would add quite a bit of weight I would think. I have a lawn care business and the 5 gallon tanks are not light (not saying they are wicked heavy but multiple it by 6 for 30 gallons of gas).

Yeah that is a pretty good amoutn of extra weight to have.

If it was to much weight then you could always just fill the second tank up half way. That would still get you a good amount of fuel but be less weight.

One other thing though, you would have to find a way to get your gas gauge to work with the other pump. You could maby add a gauge in an a pillar or steering column pod.

1 gallon of gasoline weighs around 6.5 lbs, an extra 15 gallons would only be around 100 lbs, that's less than a passenger, and it would be all tucked up, out of the way, you wouldn't even notice.

The gas gauge is just a float, if both the tanks were connected and flowing properly, the gas gauge would still work, your problem would be on any kind of incline (forward or back) the gas gauge would fluctuate A LOT, so it wouldn't be very accurate.

what? an F-250 with a gas engine?

i just dont undestand why anyone would buy a 3/4 truck with a gas engine.. less power, less fuel economy

the Triton V-10 sucks from what i've heard
the trans behind the dodge V-10 sucks

the other idea i came up with for the whole incline deal is to have the rear tank just a bit higher than the side tank. just to make it want to be in the one with the fuel pump. the other idea is to also have a fuel pump in the rear tank feeding into my fuel lines and put a regulator on it so it wont over pressurize my fuel rail since its return-less.

yeah it doesn't make sense but if i was going to get a full size truck it would be a dodge just so i could have the cummins, i do know their is a place in montana where all they do is put cummins diesels in fords.

but i can counter act the weight sagging problem by adding airbags on the rear then i can haul more weight too

Doesn't Ford own 10% of cummins? The rollback at work I used to drive was a 650 or something with a cummins ... was pretty old though, not sure if the newer ones still use cummins motors..
