fuel pump compatible?

Aside from trying to get those $%^*#@& fuel fittings off a 15 year old rusted all to hell line, is it ok to use a fuel pump from a 91 automatic AWD into my 90 AWD 5 speed? The line at the top of the pump rusted through and sprays fuel everywhere when the car is on.

I think its a lost cause getting those lines off. Even the vfaq complained how hard it was to get off and his pump had no rust on the lines...I'm just venting some rage. It's not even on the road yet and i hate my DSM.
