Fuel Fluke

ok man here is what i would do before anything else/ pull the bowls off check the floats to make sure you don't have a hole in one of them easily done by submerging in water second looks like metering blocks on both the primary and secondary side of the carb which means power valves maybe one of them is busted if you are losing pressure there is a leak somewhere /check the ground underneath the car for fuel puddles if the diaphragm in the pump is bad there is only 2 places the fuel can go either on the ground or god forbid the inside of your engine if i can be of more help please post and i will help and research
