A newbie here...Ill take a stab at this one;
We do Jeep V8 conversions, typically to LT1 and LS1's. We run nothing but CSR electric pumps on the LT1's. The constant 35GPM flow lets these motors run below 200 all day long, in sand, rocks, idleing around in low gears.
One issue with the pumps is the supply power and the adequate fusing, we run fuses and for emergency situations I run a switch on the dash that has its own power direct from the battery to assure power to the pump at all times in case of an electrical problem.
