I've got an f250 with a nice flat bed on it and a hoist underneath. There must be a better way to fill this thing with fuel. Has anyone come up with any clever solutions for this problem?

 

My fuel fillers are mounted to the bottom of my flat bed...but it doesn't tilt. Just get some fuel filler rubber hose and mount the fuel filler where you can get to it. Here's a search link to get you started. You can get them straight or angled, I want to get some to move one of the fillers so that they are both on the same side of the bed. It's a pain going to two different pumps to fill up.

Where are your fillers at now? I have a dent with a hoist on it, I chopped the bends out of a factory neck and spliced in some exhaust pipe to get the length, then bolted an angle iron bracket to the frame for them to lay in - they're extended out to be just under the outer rail of the bed, and just barely not touching the underside, basically where they'd be if it was a solid mounted one. The tanks seem to fill just as well as the factory ones on my dent that still has the box on it - I think the straight-shot to the tank helps.
