Need to replace some 6mm J20 heater hose I used during my plenum coolant bypass (running a longer line to remove a hard pipe). Trying to figure out if I need to order J20 heater hose, since I can't seem to find a store that has it in 6mm/.25", or if I can use .25" J30R7 fuel injection hose. I see people have used FI hose (of unknown ratings) as coolant line, but it's not clear to me if it's actually smart/safe. If it is, it saves me time and money. If it's not, then obviously I don't want to do it.
Anyone know for sure?
Thanks. Andy
