Mr48,your concerns were noted but everything will stay the same.I have a buddy that has ran copper tubing with joints for over ten years with no problems.As far as the filters,they work just fine,I have had them on all my old cars with zero problems,not saying you wont have them,but just got to be on top off stuff.There is risk in life,just like doing 100+mph down a 1/4 mile dragstrip(no chance of catching on fire there :rolleyes: ) but I dont tell people not to do it.The funny thing is that you guy's describe it as if the second I start the car it will burst into flames.Thanks for your concerns though.
