My chum's 300E was converted to 134A before he purchased it () anyway, threw the gauges on there and the high side was only 90psi.

NOW since I believe it was converted with one of those cheapo kits, I seriously doubt the o-rings and what not were swapped.

Would a dying compressor cause low high side pressure or is the damned thing just low on 134A?

Thanks for any help.
