[Healeys] Gas and ethanol

[Oudesluys]

Personably I have had few problems by leaving in the petrol for long 
periods (up to several years). The problems I had were caused by old 
rubber tubes desintigrating which clogged up the filters, but that is a 
well known cause after the introduction of unleaded petrol.. Some of the 
old rubber parts do not take modern fuels. Others in our old car 
community experienced similar issues over the years, but most, if not 
all, solved the problem by fitting new (not NOS) rubber parts/hoses/tubes.
Filling up to the brim reduces the risk of condensation being formed 
inside the tank as little air gets in, so does emptying the tank as the 
metal will quickly adapt to the ambient temperature thus preventing 
condensation if vented and if some condensation takes place it will 
quickly evaporate when the relative humidity of the ambient air 
decreases. If it is partially filled it takes longer to adapt and 
condensation may form and been absorbed by the fuel up to a point.
