[Healeys] Dual fuel pumps

[Alan Seigrist]

Keith -

On my Jag Mk IX there are two SU pumps which are plumbed parallel.
The SU pumps' check valves prevent back flow into the separate
opposing gas tank, so there's no need for an isolation valve.

The set up works well and does provide a measure of security against a
defective fuel pump.  This was a factory standard set up on all Jag
saloons of the era.

Cheers,

Alan
