which kit???
some of his kits don't allow for much choice , when you mount the tank the line will only reach so far
with the smc early in tank pump kits the nozzle went under the curve of the up pipe when using the hoses he supplied and the recommended mounting location on the stock fan
those of us with razor kits try to get them to the right (and left with duals) sides of the up pipe about 4" from the throttle body, trying to keep the nozzles above the level of the alky in the reservoir jug on the passenger fender
if yours is a new style progressive that uses the stock style reservoir or an old one with a different mounting location and a new nozzle feed line I'd put the nozzle where we put ours
