In-Bed External Fuel Cell

After browsing the forums for a while, I wasn't able to find step-by-step instructions/pictures of anyone routing lines from an in-bed fuel cell directly into the tank/filler neck. (Many threads discuss options, but no instructions that I could find!)

Can anyone link me to a thread or webpage with pictures/instructions? Or if you have some of your own, that would be great!

 

Following. Would be sweet to have quick disconnects to easily swap it in/out for trips.

 

Easiest way would be to set it up with an external electric fuel pump (like a cheap holley or Carter or something) with a short coil of hose an a ball valve. Run the fuel pump on a 12V cig lighter plug...take a break at the 350 mile mark or so, open the gas cap, shove the hose it in and turn on the pump until the tank is full. This way avoids screwing around with any of the evap systems and hard fuel lines that will be considered "tampering" as far as emissions systems go.

 

^+1. to the 12v pump/hose/filler method.

i've done external gas tanks on semi's for township trucks that cover far too much roadway. those don't have any of the emissions systems fuel injected cars have. and they're still a horrific pain dealing with the added head pressure, filler necks and vent tubes that were never designed to be fully submerged that are now re-routed to other parts....

modern fuel injected vehicles have even more stuff, and more issues. i would highly suggest first getting the high capacity frame mount tank(do your research on fit-- won't work on access cabs), and if that's still not enough, getting/building a transfer tank into the truck bed is far easier, and legal emissions-wise.

Wouldn't it be easier to just buy one of those truck bed gas pumps? Pretty common to see them in diesel work trucks.

 

Safer and less parts to leak from. Aux pumps are a thing of the past. I'd rather have a crank pump.

 

Exactly. And you crank about 5gal/min.
Simple. Effective. Easy. Which means most of these guys won't do it that way.
