F4 fuel system : tank -> pump -> carb -> ? where is the return ???
Hi team, I'm building a f4 powered kart, everything is done, I'm plugging the fuel lines, but I don't know where is the return line. My engine is a 600cc Honda CBR F4 2000. All the lines are ok, exept the return fuel line. Is there any or is the pump stopping at a precise pressure (but there's no regulator???)
Is the oem f4 pump running all the time ?
If not, where is the switch/regulator ?
If there is no return line for the system, where does the fuel goes, does it just drops down from the carbs or goes back to the tank ?
What is the fuel pressure required ?
If anyone had a fuel line shematic or can tell me where to get it, it would be appreciated.
It seems very simple but I want to know how the fuel is routed :
Tank -> filter -> pump -> carbs -> ? (carb out to tank - or no exit, pumps stops with a switch)
By the way, I have the shop manual for the 99-00 F4. No much info on the fuel routings...
tkx,
