Cheap aux tank build

[Griffin]

The step ladder I use has a platform about three feet off the ground, like this:



With a rubber hook strap holding it to the ladder, you'd have to try pretty hard to knock it off or tip the ladder over.


I think the total investment for my rig is $4 for the fuel line.

This works for me

Whatever your method, don't raise it any higher than the stock fuel tank, it might force gas past float valves that are just barely able to hold the pressure of a stock tank.

If your float valves are incapable of holding back a couple of extra feet of head, that's a warning sign they need looked at, seriously.
I'm in the ride-on mower tank as set-up tank from the ceiliing / stand camp. Previously, I was just using the standard bike tank and sitting it on an adjacent 55gal drum or benchtop, but became disenchanted with that. I much prefer a small, easily handled dedicated unit.

wow, glad to see that I'm not the only one that made their own aux bottle. I made mine out of a windshield washer fluid bottle. the fun part was getting the cap to seal

Found a rubber piece off a old electrical pedal from a old piece of machinery one day.
Kept the electrical from getting wet where the cord hooks up.
Fit a fuel line perfect inside.
The outside is tapered.
Fits snug inside most soft drink type bottles.
Cut a soda bottle bottom off and attached a rip of nylon cord.
Hangs wherever.
Could likely do the same with one of those rubber wine corks drilled in the center.

Now how cheap am I?
Have fun guys....

Do you want the cap to seal?

I've been using this elaborate setup: a water/soda bottle with a hose stuck through a hole I cut in the cap.

I use some Velcro straps to strap it to the top frame rail where the real tank normally sits. Because it's sealed, the bottle starts to collapse as the fuel flows out. I have to undo the Velcro, turn the bottle right side up, and crack the cap to let air back in. I've been having problems getting a vacuum reading on my Carbtune. The non vented bottle is the only thing I think I could be doing wrong.

So my question is whether the aux tank should be vented.
