Dirty connections cause resistance. This unwanted resistance may cause voltage drop available to the pumps. A quick check is measuring voltage at the battery and different places on the circuit. Anything over 3% I would consider a serious problem in any circuit.
If the battery is 13.9..
On a calcualactor plug in 13.9 x 3% = .417
13.9 - .417 = 13.48
that said the heat is probably from resistance at the wire and fuse box connection, or the fuse connection.
