fuel pump - which components to replace?

["gullwings2000" <gullwings2000@xxxx>]

After noticing a major gas leak after fill-up the other day I had the 
car towed to a service station. Upon inspection it turns out the fuel 
pump ring (the big rubber boot/seal) was seriously deteriorated as 
well as the feed/return hoses. (Not surprsied - the car has sat 
unused for long periods and I've suspected fuel system problems.)

The mechanic said if I got the parts he'd do the work, so now I'm 
just debating over which parts to replace. I'd rather not do more 
than necessary but I also don't want to be penny-wise/pound-foolish.

For all I know the fuel pump is fully functional but I'm leaning 
towards replacing it anyway. I'm wondering how far down the "chain" 
to go though, ie. the fuel tubes, elbow, tee, etc. I can understand 
the rubber components being deteriorated, but shouldn't the metal 
components still be usable? Any other things I should have 
checked/replaced while the mechanic is at it?

Thanks!
