Re: [Healeys] fuel pump

This is more or less the same as I have on my 100 that was factory 
converted to take the rare 15 gallon fuel tank when young. This has the 
two outlet pipes as you describe and two normal long body SU electric 
pumps.

However although this was changed by a previous owner there are two 
period on/off toggle switches. I can see this from an old photograph. I 
have the two switches back as they were.

So long as I keep more than about 3 gallons in the tank I have 
resilience against pump failure. I normally run with the pump fed from 
the higher pick-up pipe so that I have a reserve.

In theory I can turn both pumps on and get more flow but I have never 
found this necessary.

One thing that is somewhat of a nuisance is that a standard sender unit 
is fitted and because of the extra tank height which is about 1 1/4" the 
gauge reads empty when I still have fuel available. I could lengthen the 
float arm but then the set up would not be as the factory fitted.
