FUEL FLOW AND CAPACITY Now that the decision to change to fuel
other than petrol has been made, the first thing to look at is
the fuel tank. If of fiberglass, bear in mind the new fuels act
as solvents and most petrol resisting paints, shellac, varnish,
ethyl cellulose, cellulose nitrate and soft Bakelite suffer in
contact, not forgetting sealing compounds such as Bostic,
Hermatite, Osotite and similar leak stoppers. If the tank
resists on test, do bear in mind that if, at a later date, you
propose using Nitro Methane you will have to test still further
as this acts as a solvent on many resins, polyvinyl acetate,
acetylchloride, chlorinated rubber and low boiling hydrocarbons.
The obvious way to test is to deposit a little of the fuel on
the tank surface and see if it reacts, bearing in mind it may
attack the paintwork and not the actual material of the tank
itself, so do not get misleading results. If the tank is of
metal construction, particularly of aluminum, it should be
anodised, thus stopping chemical r
