Does this mean you are giving up on your idea of compresing methane gas?
Bernd
Not entirely, the idea is sound enough but the cost of the equipment (the pump) makes it unrealistic. I converted my car to run on LPG 4yrs or so ago and that works fine.
No probs at all. Altering it to run on Methane would be a simple task.
As I'm already saving by using LPG the attraction of methane is not as inticing as it would be if I had to rely on petrol alone and it's high costs.
Petrol here is currently about 90 pence a litre, about £5.00 a gal or $6.80, good grief the pounds dropped !!! A year ago that conversion would have been about $8.50 or so.
But anyway, our gallon is bigger than yours, so there

Yours is 3.78 liters I believe and ours is 5.54 litres.
Oh this is getting complicated.......

The bottom line is it would take a long time to recover the costs of the pump. To add insult the Government is now getting on the bandwagon and declaring a tax on the use of.....so even less attractive.
Anyways, this is straying from the forums ethos just a tad....

I need to find a pump at a realistic price, until then the idea is on hold...
