How did you hook up your transfer fuel tank

[Dreamer]

Just bought a used fuel tank/tool box for my 2005 Dodge. The local manufacturer said I may not be able to fuel while travelling due to my truck having a pressurized system and the fuel cap has to be undone to add fuel to the trucks tank. Anyone know if this is a pressurized system for a 2005. I was planning on using an electric pump to add fuel to the original tank through an adapter in the filler neck.

I use a small LP pump meant for replacement of old man fuel pumps back when carburetors were still used. It takes about 1hr to fill stock tank when hauling RV down the road. I also installed a 12V NC solenoid to prevent syphoning (which it did).

Oh ya ... ..... and i pump into the vent line in filler neck. Fuel only enters at a trickle.

I used a holley blue electric pump and tied in to the small hose by the filler hose, i put a tee in the middle of it, i put a switch in the cab and fill it going down the road,when the fuel gauge reads full i turn the switch off, Has worked fine for several years now, mine is just like yours, monte

I wire in this: http://www.oreillyauto.com/site/c/detail/BWD0/FSV2A.oap?ck=Search_fsv2a_-1_-1&keyword=fsv2a



I install two fuel lines, feed/return, and a new fuel guage sending unit, which, when used with a 3 position/6 pole switch, can be used to switch from one tank to the other, switching the guage feed at the same time, giving you a fuel reading on the auxiliary tank.



I have to question whoever you talked to about the pressurized system. There is a vent in the top of the tank to allow air in when it is being drawn, so it's not a captive system. It's a small vent, so it doesn't let a lot of air in, but it's there, nonetheless.



He is correct on the gasoline powered vehicles, but not diesel.

No, Diesel tanks are not pressurized or sealed, there is no fume containment system because diesel does not evaporate like gas. The Tanks are vented to air so pumping directly in thru the filler vent will work fine. You coul pump directly to the tank with a bulk head fitting and a roll over vale on it also. Make sure you add a 2-3 micron filter between the transfer tank and truck tank then always fill the transfer and you have solver a lot of problems with filtration.

Thanks, glad to hear that I can transfer on the road and not have to stop. I plan on adding a filter and water separator to my system but I thought it would be better to add it after the original tank so everything is filtered. In a perfect world I would have both tanks filtered but that might be overkill. Can you explain the "roll over valve" ?

If you add a good filter and water sperator between the main tank and transfer the OE filter shoud be fine. You jus have to remeber to shutdown the transfer pump or it gets messy.

I have a 75 US gal ( holds about 265 litres ) tank in my box and with a ball valve for control it trickles down into the vent pipe of the filler neck. I also have a locking fuel cap so no one accidentally removes it while it is filling. Normally I just open the ball valve for a short time while I am taking a rest break and depending on how full the top tank is how long it takes to fill up the stock tank. I have a gauge in my cab so I know how much is left. Once I forgot about it and it didn't over flow.

Last summer I filled both tanks ( 400+ litres or 110 US gals ) and headed out to Vancouver Island with the travel trailer. I saved over $80 on that trip alone and I could buy fuel when I wanted to not had to. BTW it cost me $300 each way on the ferry But I love it out there. David

The roll over valve is a built in protection against exactly what it sounds like. It's built into the vent, and in the event the truck is rolled over or tilted at an excessive angle, if any fuel begins to spew out, there is a check ball in the bottom of the vent that goes to the top and plugs it, preventing any fuel loss through the vent. When a vacuum is exerted on it, it will fall back down, allowing air back into the tank, but go back up to prevent fuel from leaking out.....

As an afterthought, I've seen these installed, and they seem to work well if the installer doesn't kink any hoses and keeps the fittings tight and sealed as they should be... ... :http://www.northerntool.com/shop/tools/product_200315501_200315501

And a filter setup will not work very well on a gravity feed system, just FYI. Not enough drop on the truck, usually..... Fine with a pump, and not a bad addition to remove excess junk from the station pumps... .

Ferry fares are a killer and it hurts tourism. I Plan to store my RV in Arizona and avoid the fuel and ferry expenses every winter that I head South.
