Will This Setup Run Reliably
 

due to tank size limits and space limitations in my b-29 project.the attached diagram is the easiest way to install a 6 oz tank to feed the os 25 that is mounted horizontally.with the tank being mounted vertical behind the firewall.i have not tried this yet myself but am wondering if anyone has in the past and how well the engine ran from full to empty.i am going to have four of this setup running at once and do not need finicky engines that die..i do have one other option but it complicates the nacell building a bit but it is the same setup as on the stafford b-24 which i have and it works fine.just currious if this would work.

I don't see why not....
 

....as long as you have proper muffler pressure to the
tank....I don't see where the extra 1 or 2" of fuel line
will make much difference.... :)

It might be a good idea to try it on a test stand before you incorporate it into a model.

scalebldr,

I second what Jazzy suggested. Definitely put it on a test stand simulating positioning of tank and engine as they would be in the plane. Your set-up looks like it will work, however, I'd make sure before building.

Just Don't fly inverted
 

You will be OK as long as you don't fly the plane upside down. :eek: The clunk will never fall to the nipple side of the tank. Being a B-29, I doubt you will be flying inverted. However, if you decide to do a loop, you will need to insure to have enough centrifugal force over the top of the loop to keep the fuel slung out to the clunk. Steep left or right bank turns should present no problems.
