Getting 9MPG / Edelbrock & Carb WANTED

Couldn't find a section for wanted so sorry if in wrong place.

I have a 90 with a 4.6 / stainless exhaust no cats with 4 branch / single point LPG. I'm getting 9mpg on LPG and about 11mpg on petrol so need help!

The LPG guy I took it to has set it up, its running on LPG from cold if a bit lumpy, but fine when warm. I normally just drive around town but rarely in traffic and have been very easy on the old gas pedal, 9-11mpg just seems like there's something wrong, any ideas?

He said that a decent manifold/carb set-up will do the trick as he can put on a better gas ring due to the inlet size, anyone got one they want to sell?

Not sure what lump you have in yours but mine is this setup

Rover V8 Edelbrock Weber 500 Carb Kit

you could try these guys:

Value ****Rover V8 Edelbrock Carb Kit*** Quality - V8 Tuner

SETUP: 4.6 V8 with an ZF 4 speed auto box in a Defender 90

I've checked those guys out before, seem the cheapest for new but I'm after secondhand to save money.

What's in yours and what MPG do you get town / motorway driving?

Ahh, just read it.
I'd happily swap 9mpg for 16! Need to sort something out asap, it'd be cheaper fueling the next NASA mission.
