Shane I have noticed it since beta 36.
I'm inclosing a link to :
Design Analysis of the P-47 Thunderbolt
by Nicholas Mastrangelo
Chief Technical Publications, Republic Aviation Corporation
Fuel tanks are self sealing and mounted internally such that the super charger ducting and wing mount bulkheads protect them.
http://rwebs.net/avhistory/history/p-47.htmFor the info below I have a detailed cutaway drawing at home for the P47. The same one found in most popular P47 books.
There is a large oil tank, small glycol tank and water reservoir behind the engine. The main tank is "L" shaped, such that the forward part goes up vertical just infront of the canopy for a filler valve location. Most of the main tank is below the pilot and protected.
If the oil tank is blown away the Pratt & Whitney R-2800 is designed to run with residual crank case oil, and/or 2 or 3 jugs damaged. From underneath the jug is well protected by virtue of the ducting structures for the supercharger. Thats why it made such a good Jabo.
IMHO - By the time the plane gets to the combat zone, the fuel in the forward upper part of the main tank would be drained down and not as much an issue from fragment or bullet damage. <-2c worth
Sorry if I'm describing a PERK plane;)
