H1 SU versus Ruby Zenith sidedraft

[JonE]

For me the big advantage of an SU is once set up you can forget about it. Mine came from a jumble sale for £1, was cleaned up with paraffin and went on the car.  Thus I must say £250 sounds an awful lot to me.

Chris, I'm happy to pay a quid commission too if you manage to find another one....

THanks all - very useful.

So what about the comparison though - I now understand they are 'fit and forget' and enable you to run on dirty fuel, but what is the physical difference in character? And how efficient are they in comparison? Is the advantage because of their variable nature.. i.e. that they have more range?
