Pete1burn... The way I install all my tanks... I use silicon sealent at the frt. of the
tank just around the hole in the firewall.. I foam where the tk. sits, and I either
use foam to tighten any small movement at the back of the tank. The silicon holds
the tank well, seals the whole, yet still pretty easy to remove... I'm still on the tk.
that came with the model... On tanks/fuse's thats hard to see the bottom of the
fuse/tank area, I drill a small hole/s in the bottom of the fuse in the tk. area just
before the rear bulkhead just so as to tell in case the tank is leaking... Have not
needed it yet... Bit I have seen a few models that would have benifitted from it.
