New & Emerging R/C Helicopters > Hopper Tank 2oz Installation?

I've been having difficulty installing my hopper tank. The rubber vibration isolation grommet does not seem to fit into the mount hole, for starters. Secondly, I am not sure how to install the plumbing such that the keyhole shutoff in the main frame can still be used. Would someone please point me to a decent pic of an existing installation that might help answer my questions?

Hey Richard,

The grommet is tight but it goes in the hole.
I did not use the keyhole shutoff after installing the hopper tank.
I used the T-Filter and shutoff/plug arrangement to shut off the fuel. That is especially needed when you are filling the tank through the bottom of the T.

I feel your pain with getting that grommet into the mounting bracket hole.. but, I've managed to get about a dozen of them in regardless.

Just work it in a little at a time.. I use a small flat blade screw driver to 'ease' it in a little at a time. Once you get a small section in, you just have to find a way to not let it pop out while you move to the next section and after you have about half of it in, it's easy to finish it up. I do not put anything on it for lubrication either...

A fuel line from the TOP or VENT of the hopper tank goes to the CLUNK line of the Main Tank....

I do not use the KEYHOLE with a hopper tank, I use a TEE FILTER.

A line from the clunk on the HOPPER to one side of the filter, and the opposite side goes to your Carb. The other line at 90 degrees has a short piece of fuel line and a plug. For this, I like to use a KSJ combo fuel shut-off plug... makes for a simple neat installation. If you don't have access to the KSJ product, you'll need a fuel shut off as well.

I suppose you could route this line back through the KEYHOLE provided but, it seems like a lot of extra line to me... So, I chose not to employ it.

Good luck!

Sorry, I can't send any pix right now...
