I am refurbing a Z B25, and adding some fuel cap details to the top wing center section. I know there are 3 per side, with, I think , 2 different sizes.
Looking for one of you B25 gurus to help me with info or photos of location and sizes.
thanks in advance-

I'll ping my buddy, he has one and should know

I suppose, there was only one size of them. Why there should be 2 different sizes?

Final verdict on fuel caps :
Every picture I found confirms that the larger cap is forward, with the smaller aft.
The 3rd cap, per side, is located horizontally across from the aft inboard cap, and is also the smaller variety.
This pic, although poor in quality, shows the setup yet again. The plastic model guys are usually known for getting the details correct.

Better is to find pictures of real bomber, because model is just model. If designer of the model would want, there would not be any gas cap. I hope you see the think.
How about aircorps library?
