Do I understand this correctly?
 

It is OK to use the World Models fuel tanks but the tanks stopper should be replaced. Will the sullivan stopper work?
Thanks,
Chris

Chris yes and yes

But unless you are using gas and not glow fuel there is no need to replace the stopper. Be careful when tightening the stopper. I've had 2 World models tanks split right at the seam where the stopper goes in from tightening it too tight

It's going to be a glow powered (OS-FS70) Frontier Senior. Using it as a payload hauler. Unfortunately I took the wings out of the bags last night and I have 14 damaged wing ribs [:o]. Not a mark on the box. covering or wing bags. I have already completed the fuselage or I would send it back. I'm going to call World Models tomorrow and see what they say. I had planned on adding flaps but not rebuilding the whole wing. OH WELL.
Thanks for your help!
Chris

I have several WM planes and recommend them to anybody but I still toss the hardware and especially the fuel tank.

Think about it. $5 for a new tank or $500 for a new plane
