I did some looking around and the only two places that re certify CNG tanks are the USA and India.


LPG tanks are easy enough to have done. Unless the stance has changed UKLPG are not worried out the age expiry of LPG tanks.

And that'll be Type 1. The larger tanks in an Ovlov will be Type 3. I've never seen re-cert for these.

To my surprise, I received no notifications to my mailbox that someone has replied to this topic from my last message, accidentally found them in my spam folder. Sorry for my delayed reply.

Thank you both for your answers, CNGBifuel especially. You really gave some great information and some new ideas for me to make plans for the future.

I would really like to keep the car running on CNG as long as possible, but it will not be an easy task. I had an LPG converted car once and running it was a pain, most of the time: LPG filters clogged, problems with air mixture, spark plugs, lack of power,coolant leaks, air pockets build up, new regulations about the conversion struck my model of car so the LPG tank needed to be relocated from the spare wheel space to the luggage area.... I said to myself then, "never again on LPG"

This Volvo Bifuel car got to my possession almost by accident but I am hooked now to the amazing bland of classic Volvo comfort and build quality and above all, frugality. With local prices of natural gas and with my light foot on the throttle my driving costs me 5 euro per 100 km on an average cycle, which I find amazing. Car works great, transitions from petrol to CNG are seamless, if the car is hot or parked in the hot area it almost fires up immediately on CNG. Did some serious towing with the car through Europe and not even once felt lack of power running on CNG.


So, I got granted from the inspection authority less than 4 years now to exploit the car on CNG until the next one and then I am supposed to find a solution. One would be to obtain a used tank(s) from scrapped vehicle but even looking at the newest models of 2nd Bifuel Volvo generation there will be no ones with expiry date beyond 2025, which does not give me much time if I succeed in finding a tank.

Second solution would be finding a brand new Chinese made Type I tank which should fit by its dimensions in the space of main tank and leave the space of 2 small ones on the front empty if I cannot find similar ones.

Third one, the least desirable one would be to convert the car from CNG to LPG and use as much of the original CNG installation as possible.

Thanks for the tip but I did not manage to find a decent tank for a Bifuel Volvo in Italy and they are quite rare.

I get confused by schematics of a V70 second gen bifuel Volvo I am finding on the internet. If I understood correctly, high and low pressure regulators are 2 separate devices on different locations on the vehicle? I know where is the low pressure one (Necam Mega), but where is the high pressure one located?

So, to make everything simple to ask, I am only supposed to find a CNG tank with its dedicated electromagnetic valve which should be installed straight into the current space instead of the old one? Everything is just "bolt on" and should simply should work as it is without any modifications? There are supposed to be no incompatibilities regarding pressures, pressure sensing etc.?

Thanks.

Sorry, I can't answer your questions, start a new thread, specify which car you own.
