leaking Petrol

[Mr Fujiwara]

hey guys,
i have twin 45s on my 4age bigport.

i run a Facet pump with one line straight to my carbs, and it seems when i have the car turned off it will slowly start to leak out one of the trumpets, im thinking perhaps the tank is becoming pressurized over the day, i seem to be leaking a fair bit of petrol, and its expensive so i'd like to know how.. leaks about 1 drop ever 5-10 seconds

IF it was becoming pressurized, whats the best solution? i was thinking to just drill a 1mm hole thru the top of my fuel cap, as i figure evap thru the cap would be nothing comparerd to the amount im loosing out my trumpets.

Come fix my car when you're done.

the carby is the issue by the sound of that. is the float level correct? what pressure is going to the carbies? it's either flooding or leaking somewhere and dripping out of the throat.

i had a fucked seal on my fuel cap, i would fill up on a hot day, drive down the road and watch it dribble out as i drove along, dont drill a hole in the cap, cos it will for sure come out of there, sound like the carbs are the issue
