Land Rover Discovery 3.9 EFI ES, with LPG system fitted. It is a single point system with a valve saver system that lubricates the cylinder head valves to stop them running dry.
As for the LPG tanks it benefits from having two sill tanks along with two more tanks in place of the original petrol tank holding 150 litres#over the 4,

But no way of telling how much LPG I have in the tanks.

Will this sort gauge work on this system ??

Its my 1st v8 and 1st LPG

Thanks lz

It'll probably do it but when I had my 3.9, I used dead reckoning because the gauge fitted used to go from full to red in about 30 miles and then run (if it didn't break down...) for about another 140 miles.
I kept a fuel log with MPG worked out at every fill up.
