fuel pump question - 8V71

And it's a doozy...   

which port is the input and which port is the output?  My pump has two ports, one above the other vertically.  It's been too long since I took it apart and I lost the picture I drew...

thanks, Brian

Should be 2 different sizes the larger is the suction side and most are on the bottom

good luck
