Safest place to place floor jack on MGB

[MGALUVR@aol.com]

I was wondering where the best place is to place a standard garage floor jack 
under the rear end of a late (78) model MGB. I need to get to the fuel pump.  
I have heard that jacking it up by the differential is OK, but other people 
say thats not a good spot and can cause rear end problems, and possible 
damage to the axles. Anyone have any suggestions as to the best and safest 
spot?
