Do OEM hoses really weep R134a 700

1991 740T Wagon, 190k miles,

I read in the FAQ that old R12 AC hoses (the flexible ones in front) may weep R134a when converted and the system is emptied of mineral oil. I'm going with an esther oil-lubricated AC conversion (I read in the FAQ that this is best and the volvo kits use this) and don't want to replace these hoses (they look in good shape) unless I really have to. I'd consider another oil if it meant keeping these hoses intact. This project is getting very pricey and I need some cash for a new high-pressure line. Or with my miles should I just get new ones anyway?

Also, can anyone source me the high-pressure line. Mine is black and runs from the condensor, bolts to the bottom of the engine compartment, and runs to the firewall by the accumulator. I'm having trouble finding one.

Thanks guys

Evan
