ABS Aire in the lines

Bought a 87 325is w/ 100K on it. Brakes went out on it about two months later. Replaced the the master cylinder and discovered that the fuses were out on top of the ABS Pump on the front left of the car.
Replaced the two fuses but the light doesn't come on in the dash.
We can bleed the brakes and they will hold pressure until you start the car and after a day or two the pedal is all the way to the floor.
I have replaced all the rubber hoses and brakes on thecar and it still does it. I pulled the two fuses and I have brake pressure on it again.
Any suggestions , Is my ABS unit shot ?

Thanks.
