Fuel tank mounting

[Old Fart]

Probably a simple question - but as this is my first flat bottomed tank, I'll ask.

Installing a 16 oz Du-Bro tank in my 100" Hangar 9 Super Cub. The mounting platform is flat - so is the tank bottom. Do I need to "wrap" the tank in foam like my older glow planes (which have round or rounded tanks and a bulkhead to go through), or just zip tie it to the platform.

Zenoah G26 if it makes a difference.

I use foam just under the tank.

velcro works great

Damn - two answers in less than 5 minutes (Thanks!)

I thought I was ready to run it up tonight, but just realized that I haven't installed the fuel filter or the fill "T" and fuel dot.

Actually, both of those guys have it right. Place a piece of foam under the tank, then 'Velcro" it to the mounting platform.

Please don't forget a good filter. Those thingies that people use with glow engines are not examples of good filters. A filtered clunk will save us having to answer questions about a sputtering engine on throttle up later. Use another one just like it in the fuel can and forget about dirt introduced to the engine by the fuel for a year or so.

Ahh, Tired Old Man - I remember you from the RCGF thread

What would you consider to be a _good_ filter? Filtered clunk?
I bought a pair of filters from Chief - I'll have to look up what they were. I'll see if my Jersey fuel can has a filter on the clunk

Don's Hobby Shop sells some nice filtered clunks. I have been using them for several years with excellent results.

[Tired Old Man]

This should cover the answer. Can be had at average saw and mower shops everywhere.

Filtered clunk is only useful where you have a three line tank. Which I use anyway, but nearly all people I know use two.
