Rich and all: When I changed brands I did what the manufacturer said to do. As for the firewall, the first roadster I saw them on located there was W & W. Hey they were firemen and as I said when activated all liquids end up on the back of the grille shell. I can guarreennttee that. I had an oil fitting get loose and all the oil was up front; there was NONE on the firewall and the leak started 6" from the firewall.
Ken Walkeys sealed engine compartment liner caught fire one time and all the nozzles (6 or
around the engine were mounted level with the valve covers. The product flooded the engine compartment and the fire did minimal damage. He told me he mounted them as the instructions directed.
I understand what the rule book says and will comply but currently my exhaust system and the exit is above the pan rail and frame but I can easily add 2 more nozzles in the loop. Just something else to make sure I do prior to running next time, no big deal....JD
