Whats the difference between the (92 302 4x4) 16 gallon pump & the 19 gallon.
Because i picked up a used pump. The new pump sits lower in the tank then my old one(doesn't fit) Does that mean they gave me the 19 gallon instead of the 16 gallon pump?

 

I bent it less then a half inch and it fit. so im going to go with it,

 

Also which line is the return & pressure, i find it had to tell from steves diagram

 

Look where they connect to the fuel rail. The one that dumps straight into the injector rail is the pressure side; the one that's routed to the pressure regulator is the return. Then just follow that color to the tank.
