Fueling issue

Howdy guys, im running a brand new tanks inc tank, brand new sending unit, brand new fuel lines, brand new mech fuel pump from mancinis and a rebuilt edelbrock 600 carb from rileys rebuilds.

Once the car gets up to around 180-190* it starts starving itself of fuel, especially if you Try to really give it the gas.

at first i thought vapor lock maybe, but ive since installed header wrap, fuel line insulation, a insulated carb spacer, made my dual hood scoops functional and its still an issue. It runs great right up until it starts getting hot then the fuel filter looks like it goes darned near empty.

Not sure what to do next. The mech pump is a carter from mancinis. i do NOT want an inline pump, they are loud as hell.
