I have been toying with the idea of adding a 30-50 gallon tank in the bed of my truck. Been looking at the transfer flow systems (www.transferflow.com). Has anyone had any experience with this kind of mod? I have a fiberglass tonneau cover and want a kit that will fit under it. Any ideas? Thanks in advance.

I have a 70 gal the tank from transferflow and the main body of the tank is below the top of the bed. Ain't the fify gallon a bit lower. Transerflow is really a good company I would imagine they could place a fill cap into the tank a bit lower if this is required for you tonneau cover to close. I had them ship tank to a frt terminal near me and I picked it up there save a bit on freight and installed the tank myself.
 
transfer flow tank install

You can see how high the fill nozzle is with the 70 gallon tank. Tank is about3/8 inch higher as I place it over a bedrug.



Hope this helps, let me know if you need any measument or?



I am very happy with my Transferflow tank, you can see the lighter color of the camper shell above the Almond color of my trucks bed rail

abdiver,



That setup looks great. I see on transferflow's website that they have the computer controlled pump with LCD display. Do you have this as well? Was there any problems with integrating into the factory electronics? Although the automatic transfer is cool, I am one who would like to do it myself by flipping the switch. Let me know your thoughts please. Thanks for your help, I am preparing to head out west from Nashville, so the extra tank capacity is a lucrative option.

The only thing I would have done differently with drilling the shell is I would have went to a Marine/boat store and got a SS flush mount fuel fill and corresponding fill hose... you would have not needed that large of a hole in the shell, nor would you need to be 9 feet tall to reach into the shell (or climb inside)... and you would have a nice chrome fill cap on the outside.

I had a 98 gal TF tank in my '95. It worked great but (obviously) took too much of the bed. The system/design is tops but pricey. I had the LCD and liked the display features.

I opted to save the high cost of the LCD display. The std unit comes with the computer controlled automatic transfer. I just zero out my tripometer when I fill up and know that when I get 1500 miles on it, its time to fillup pronto. Also after I have driven about 1200 miles as my 70 gallon in bed tank is empty, so now based on my stock fuel gauge I see how much fuel I have left. You can splice into the wires and manual run the pump. You would splice into wires at transfertank drivers side, and run wires to a switch in cab. I also wanted to do this manual override but todate it just ain't that important. but I do have the color codes of the wires so I can do it incase I really needed to.



I powered the unit from my painless fuse block, you need to splice into your fuel gauge wire (see pictures) I cut soldered and shrink taped them. I plan to do something to protect the loop as I would hate to have a stick get kicked up by a tire and catch the loop a mess up my wires. Though I imagine this would be rare.

Yes, I agree with a different fuel fill, only because I have a locking fuel cap & I am conserned about rain getting into the key slot and then migrating to the fuel. I have a call into Transferflow regarding this issue waiting for an answer from them. I installed their Camper fill kit, with I had to modify to fit my shells angle as there camper bezel is set up for a straight wall where as a shell has an angle. If I had an exterior door to cover the locking fill cap rain wouldn't get into the locking cap. At this time I am using the stock non-locking cap that came with my transferflow tank pictures below. I am 5' 10 and have no trouble with the height of the fill pipe as you know the fill needs to be higher that the top of the tank.

Can you tell me how you wired up the painless fuse block. I am fixing to add a few off road lights up front, along with this mod. So, I would like to have a fuse block that could do all, plus protect my factory wiring. BTW, your setup looks great! Thanks for the pics and information.

painless fuse block

i recently installed my painless. after reading the boards and tearing into my interior a little, i decided to mount the painless on the passenger side, inside the space under the dash next too the the glove box (area between glove box and door under the dash). if i need to check a fuse all i have to do is take off the glovebox which is a lot easier than trying to pop off trim interior somewhere.



Rather than going through the firewall i ran the power and hot ignition wire through the rubber boot that feeds the passenger door and then into the engine compartment (pretty easy and no drilling). Power wire going to the passenger side battery and the pink hot/ignition wire through the split loom headed to the factory fuse box (TIPM module). My only worry is wear on the wire from the boot to where it feeds into the engine department due to opening and closing of the door.



I found a link on here somewhere for a good place to find the hot ignition wire to splice into (without ripping out the dash). Directions on where to find the hot were from the installation manual for a Jacobs E brake on an 06 CTD.



hope this helps
 
Painless install

Diesel Thunder. I purchased the weather proof model. I found plenty of room under the hood on the passenger side just to the side of passenger side battery. I made an L bracket from a piece of aprox 4" x 6" thick sheet metal drilled the holes in the firewall flange and used nylock nuts on the small bolts to ensure they didn’t loosen in time. (see pictures below) to attach the L bracket and mounted the painless wiring kit on the bracket. The install was easy and it will be easy to access if I have a fuse issue. Should also be easy to run wires from there. I ran the hot wire from the passenger battery. Its been a bit over a year many other projects since then so I forget exactly with wire I used for the keyed side of the painless. Note the pink wire under the dash I accessed the firewall through an existing rubber grommet directly behind the clutch pedal area if you have a stick the clutch just misses hitting wire (note from a picture I immediately placed it under the carpet so the clutch pedal would not interfere with it. Hopefully some one will tell you which keyed wire that is I know I have it written somewhere. Let me know and maybe my brain will work better later. I think it may have been a wire to cigar lighter check to see if the lighter is controlled by the key switch.
 
Pink wire with a yellow stripe

Diesel Thunder The wire I spliced to was Pink wire with a yellow stripe my truck is an 05 so I don't know if same color wire codes for your year truck



If you want better pictures give me your email address

Abdiver,



Wow, thanks for the great pictures. My truck is an 05 six speed, so our wiring should match. With regards to the pink with yellow stripe wire, that was for the keyed hot on the painless setup... correct? I too will be getting the weatherproof model to mount under the hood. I really like the idea of the transfer flow setup. I live in Tennessee, so we routinely see 20 and 30 degree low's at night during the winter months. I do run a fuel additive and have never had any gelling issues, but what about you. I would think that the tank in the bed would get quite cool, but have you had any gelling issues? Thanks for your work.

I "cooled" mine down to 5*F about two weeks ago without any issues... as long as you add the antigel before you fill (so it gets mixed up), you should not have any trouble at those temps.



**I will also add that I am running through a fuel-water separator (home-made) and a small Fleetguard FS1251 filter at the same time... it would still gravity feed without the pump at 5*F. **

I am just north of San Francisco in sunny California, This winter was one of the coldest for this area, But it only got down to 30 a couple of nites only No fuel gel problems here. :cool:
 
Diesel Thunder,

It looks like the Cigar wire is a Red with Yellow tracer and NOT Pink with Yellow tracer. Will take a look at my install a confirm tonite.
