Before anyone says it, I know that lpg is a 'dry' gas

I have just scored myself a nice GQ on gas, but unfortunatley the LPG gauge doesnt work, I was wondering if I could just run it till it runs out of gas? I know this isnt good for a petrol system as it sucks all the crap of the bottom of the fuel tank, but would the same problems arise on the LPG system ?

Any ideas would be great,

thanks all

Yup, just run it until when you accelarate nothing happens, then sw to petrol on the move. Normal way to do it, means your running on gas/gas/ not liquid/gas....

Never caused a problem doing this in my workvan every week for 3 years, a good tip is to drive a few km then park it on petrol one night a week to keep the carby seals moist, also makes clutch starting possible if you have a flat battery as some LPG systems won't bring in the gas solenoid until there is engine vacumn up.

Chad has had gas only on his jeep for the past 10 years & has never had any probs with any seals, or anything. Runs out of gas frequenty because he has never had a gauge. No probs there. If you have a flat batttery, his gas system has a 'purge' valve thingy on the condenser(?) thingy which you push to put more gas into the carby & you can clutch start as normal.

Running the tank dry has no side effects at all.
The only word of warning I'd give tho is....

When you switch from LPG to petrol with a warm motor there is a chance that the carby float will "implode"....IE crush itself inwards !!. This will cause the engine to flood from the excess of petrol.

Relax there is a soloution.... fit a neoprane float, most LPG conversion shops do this right from the word go ...some dont... so it would pay to check that you have a neoprane float in your carby.

Holley carbys are extreamly renound for this imploding float problem that was untill they made the neoprane float to suit.

I just did this accidently because my guage is no good either. no worries at all..

Thanks for your help guys!

Ive just found out that my LPG tank is outa date and have to get it re-tested so, im going to run it out and take the tank out myself , and then run it down the the test facility. HOPEFULLY it will pass. Ive been told conflicting stories about tanks passing there tests, and I dont feel like buying a new one

Has anyone else had there tank re-tested before?

BTW, I have a Stainless Myttons LPG tank.

Thanks agian.

Got mine retested, passed fine even though as I found out the AFL valve doesn't work

in the process of getting mine checked, wont be ready til early next week.

How much are people paying for tank inspections ?

We pull the valves out on purpose and only do a full fill when heading out the bush and need some decent range. The car is never parked with a full tank.

it will cost you more than say a APA tank, because mytons have a multi function valve/guage/fill system.

thats nice information to post on the internet

But, for all intents and purposes, before AFL you could do this on all tanks

I've had three tanks retested, all passed no worries. Cost is $140 for a four port tank (APA) and between $200-$300 for a multi-valve tank.

I used to run our AU wagon's gas tank dry every time - no dramas. I have recently ran the tank dry on my new falcon 3 times with no dramas. When the gas runs out at freeway speed or similar, you can back off the throttle and drive it for another 30-40km as it gradually runs out.
