Can't comment as to political correctness, but True Details used to do several versions. 'Korean War' version was the modified WW2 75-gal. drop tank for the 1/32 F-80 [also used by Corsairs], #TD32505.
They also did a 1/48 BLU-32 500 lb. napalm bomb [used by Skyraiders], #48528. (Also the BLU-10 250 lb. version, #48527.)
With Squadron's current supply situation, I have no idea whether they're still available. You could hunt on the usual auction sites and Amazon.
For Corsairs, it would be a ridiculously simple conversion from a pair of 75 gal. tanks and some scratch-built grenade detonators. Photos of the real thing should be available online.
