I'm puting a 50hp wet shot of NOS in my car & as I have driven LPG cars for the last 20yrs & I was wondering if the electronic safety shut off valve that must be fitted to all LPG tanks would be OK to use with NOS as a safety cut off at the tank, not worried about fittings but more if the NOS will have any effect on the LPG fittings, o rings etc in the shut off valve, thanks

why will you be using the safety valve for on a nos bottle?

Should have spoke to you about it on the phone earlier, thought it would be safer and save turning the bottle off, really know sweet f/a about the stuff n I thought less chance of leakage ??????????????, Might give you a call about it during the week.
