Header Tank

[diyman]

Hi,Im just making sure i have connected my Header tank properly.
I will explain running from the exhaust.
Exhaust through in line filter to the top inlet of the main fuel tank,bottom outlet through the filler valve to the top of the header tank.The middle outlet is sealed with a plug.the bottom outlet goes thru an in line filter to the carb.
I filled the header tank thru the center inlet then plugged it with the proper plug.

I did have another idea of connecting it where by going from the carb.
Carb to in line filter to filler valve to bottom of header tank,center blocked off,top of header tank to bottom of main fuel tank,top of main tank to in line filter to exhaust.

It seems to me that when i fill my helicopter,only the main tank fills up being as the filler valve stops the header tank from filling.I havnt had a problem with running as i can see the fuel running to the header tank from the pressure from the main tank caused by the exhaust.

If i connected it the second way the header tank would fill first then go on to fill the main tank.
The way i have it now if the fuel looks like its getting low in the header tank i can always top it up thrugh the blanking plug in the header tank.

All the best,Brian.

Hello Brian,

This is to say that the way I have seen headers filled is from the carb line at the filter to the header and then with the line to the main tank from the top of the header when the fuel fills the header then the main tank is filled. I have a pic to show you of sombody elses that shows there setup. This way the header normaly stays full or nearly full if any air gets trapped in it from the fuel line.
