[Healeys] I'm stumped

[David Porter]

BJ7 sat for 40 odd years. Fuel line from pump to carbs clear. Tried two new
pumps. One SU square body (tried two different bodies) . Replaced
steel/brass banjos to rubber hose with nipples and installed a facet LP
pump. Replaced fuel tank believing the pick up tube was rusted through on
old tank. Checked filler breather. 

 Symptom: car runs for a couple miles and the pump stops pumping (looses
suction) However will pump a steady/adequate quantity when disconnected from
float bowls. Floats and level adjustment at spec. New needles and seat. Hot
or cold.. tried every fix know to man. 3 times at least..still no joy

 What is going on?
