Hi when i bought my sport supercharged it had a gas conversion with the tank in place of the spare wheel i went for a run out today from cardiff to tenby but did not get there and back on 1 tank how many miles roughly will they do on a tank of gas i managed 19.8 on the lie-o-meter but fing 150 miles not very good or could i get a larger tank fitted

My 90l tank gives me 260 miles

Thanks is that mounted in place of the spare wheel asi only managed to get about 35 liters in mine with about a quater of a tank left in it

Yep
Under the back between the exhaust

ok so i must have a problem as i only managed about 150 miles and only managed to get 35-36 litres in the tank when the gauge said it only had a quarter in it

Perhaps it's because the tank is not fitted horizontally but at an angle and the floating thingy inside the tank doesn't compensate for this. Regards etc.,

WAS: 2006 RRS Supercharged

I can't see how the rank could be fitted any other way

I think there us another issue

ok so perhaps i will see how long the gas lasts and go beyond when the red light comes on as the system has had a new sender according to service history

don't go off the LPG Gauge they are not good , use your mileage trip . 75lltr I get 248 miles 2007 SUPERCHARGED HST

well it is full now with 45 liters of gas so i shall see how far i get i did speak to a lpg guy yesterday and he said he could see a problem straight away as the tank is sat at the same angle as the spare would have been which is about 25/30 degrees anyone no if he is telling the truth

Has anyone got a picture of the rear of there sport with a gas tank mounted so i could possibly see

I had an Lpg kit fitted to a previous car:

Lpg is not as efficient as petrol so you need more of it to do the same job. Mpg dropped about 15% on Lpg over petrol.

Lpg tanks are designed that they will not fill to capacity so a 90 litre tank will not actually hold 90 litres, IIRC something like 80% capacity as Lpg is stored as a gas.

Car still uses petrol to start and Lpg does not cut in until engine up to temp so in winter you need to make sure you keep petrol topped up.

After 40k the big ends went, never had big ends go before on any vehicle so always suspected it might have been the Lpg but could have been a coincidence.

Enjoyed the petrol with diesel economy but it is back to an oil burner for me

Thanks but took advice of local installer and ran it till it started flashing and beeping then filled up and got 80 litres in so now i know my gauge is no good as others have said ignore the gauge and go by miles

They are not designed that way, the 10% you can't fill is Air as you can't have an air vent like a petrol tank


Before you tell some it's stored as a gas maybe google what lpg stands for lol

So I have a 95 litre tank and I got 80 litres in that to
Me sounds about right so why would I need to google lpg I know what it stands for
