A few Acmat fuel tanks coming up on Mod-Sales, hopefully some other Acmat gear will come up. Whacked a bid in as saw they had the locking cap system. What is odd though, is I thought the locking cap was sitting on the top of the tank, but after zooming in it appears to be a second fill point...... Seems weird, locking cap under the floor and non-locking cap on the exterior fill point :???
