tanks
Re-read the earlier posts guys- this is exactly what I said.
The simplest way is with two tanks but some designs don't allow for it or it may be after the fact.
The rear tank should be back-wards with respect to the back-wards engine - facing forward - you know what I mean ---"clunk to the rear". (:
Marcus, You may try to make room for the two tanks now before you get any further along. It will be cheaper and save a lot of headaches later.
