Default Fuel tanks

Hi there,

I just bought myself a nice little PAW .09 R/C engine. This is not the first diesel engine that I will be running (I already have quite a few that I've run on the bench), but it will be the first diesel that I am going to fly.

The aeroplane that this engine is going to go on is a 30" span fun fly. The 'problem' that I can see coming is to do with the fuel tank. The diesel fuel tubing that I have and can get is fairly stiff when compared to silicon tubing for glow engines - it won't do for a clunk line in a conventional tank. I am thinking about using a tank of around 2 oz capacity. I am not entirely sure how I should go about the fuel tank. Any suggestions? I was thinking about soldering a brass tank together to fit the aeroplane properly, but I'm not sure on what kind of pickup I can use. How does everyone else go about these small fuel tanks? It will need to work in all orientations, as the plane is afterall a 'fun-fly'.

I do not know if you can get the HAYES TANK in the UK or not, they do go down to 2 oz the clunk line is compatable with diesel fuel and so is the little bung carrying the fuel which attaches to the chunk line inside and then just attach for carb line to the outside where it exists the tank bung I use these tanks from 2 oz to 8 oz on all my diesels, well not all I have a few planes wilth sullivan and dubrow tanks with the stopper (bung) changed to glow to gas martin

WOW I should not do these posts half awake just fixed the awful spelling and grammer, the hayes tank does use a very small stopper (bung) with an O ring, and the collar that it goes into has a metal ring to prevent any splits, a very good design and with the 2 nipples
on the front , can be used as a 2 or 3 line setup if a 3 line , one need to drilled out to open for the pressure line to the muffler

Eric Clutton sells very thin wall tygon fuel tubing that I have used in 2oz tanks. Also Dubro sells neoprene tubing and if you can find an old pack that has a thinner wall it is quite good.

Thanks Francis

You can get diesel tubing from PAW. As mentioned make sure you use the right tank bung or it will swell and go soft.
