Assuming proper connection/setup,
THAT reading appears to be low, i.e., one pump only, or one pump may be faulty, or a bad connection(?).
While monitoring the current, pull the FP1 fuse on the main panel and see what the current is. (Current adds in this case. So, pulling only one fuse and seeing what current remains will tell us what the current draw of each pump is.)
Here is a schematic from a 90 FSM which I hope is similar enough to work on later mo cars too. (Someone may correct me if this isn't accurate beyond the 90 Zs)
Fuse location (1990): one on the main fuse panel, one on the auxiliary panel accessed behind/under the passenger knee panel).
