The metal fuel feed rail obviously has a T off to to a "rubber" fuel pipe to feed each of the carbs. On most of the engine photos I've seen, each fuel pipe to the carb is looped up and over to the carb such that the top of this kinked loop is above the height of the return fuel rail.
I assume it is configured this way so that the RETURN fuel rail is always filled with petrol, is therefore pressurised as it should be and therefore avoids air locks in the return fuel system and lets it do its circulation job properly.
ANY THOUGHTS ? (Have a look at yours)
On my car the front pipe feeds downward from the rail to the SU carb. The rear pipe did the up and over loop to the carb over the throttle bar. Not so long ago I changed its path to go down and under the throttle bar so the fuel feed pipe fell downward to the SU carb. This MAY BE a factor in my rear carb flooding issue as the return fuel rail/sytem has attracted air and gunk into that return line. (I am speculating. PS Its NOT a float bowl/needle problem)
Just wanted observations on how the fuel feed system should be configured.
