Tank Pick Up Improvement

Hi Bob
Yes looks for sure Norvel. Good enough tank. I've had this one about 10 years but not happy with the 25% fuel not consumed on flights. I fixed it at the moment. What is inside your tank to ensure full amount of fuel getting used?

Thanks

Iceberg:  I think you did the right thing by adding the flexible tubing and Pipe, (?) to extend to the bottom rear of the tank. If a CL it should be to the outside rear corner where all the fuel gathers.
   Great job.
Most tanks use a “clunk” or a weighted piece with a hole at one end to pickup fuel. Google it. I think they are sold with Sullivan fuel tanks. Tank, rubber stopper, tubing for in, out, overflow and a clunk pickup. It is just a brass or lead piece with a hole at one end for pickup and the other end the size of the tubing you would use.
Easy, Peasy.

Happydad.    

If your fling R/C i would go with a clunk set up / I have heard those tanks get leaks to them ,, i think it was Ken for one that said something to that . Here's a link that has some good info ... . https://www.modelairplanenews.com/fuel-systems-made-easy/#visitor_pref_pop And U get a news letter

Iceberg, that tank and engine aren't mine. I lifted
the photo from ebay.

Hi Bob
Thanks for finding the picture and identifying the tank brand.

Yes the clunk style I have had on some other tanks before nut not this one. I use it on a boat so the centrifugal slosh of the fuel is greatly reduced from a plane. But I might put a "clunk" pickup in there anyway.

Thanks so much!
