Fleece Performance 91-97 Dodge Ram 5.9L Cummins PowerFlo Lift Pump Assembly
On a 1991 to 1997 Dodge Ram with the 5.9L 12-valve Cummins, two things wear out together: the engine-mounted mechanical lift pump and the in-tank fuel level sender. If your first-gen or early second-gen truck smokes and falls on its face on a hill, cranks long after it sits, or the fuel gauge reads empty on a full tank, the Fleece Performance FPE-PF-CUMM-9197 PowerFlo kit takes care of both. It puts an electric dual-gerotor lift pump in the tank, with a new sending unit and float built into the same assembly.
The P-pump (or VE pump on the earliest trucks) needs a steady fuel supply at its inlet. The factory setup uses a small mechanical lift pump on the side of the block that pulls fuel all the way from the tank. The PowerFlo moves that job into the tank, where a pump pushes fuel instead of sucking it. Fleece uses two gerotor pump sections in one housing and an active fill bucket, so the pickup stays full without a sump or draw straw and you avoid the familiar quarter-tank starving. Fleece rates the PowerFlo to support up to 800 HP. The kit includes a block-off plate (FPE-CUMM-FBOP) to close up the port where the old mechanical pump was mounted.
Tee a gauge in after the filter and watch supply pressure at idle and under load. Pressure that drops off as you climb a grade points to the lift pump or a plugged filter. Replace the filter first and test again. Also make sure it is not the transmission: an automatic that slips or drops out of lockup feels a lot like a power loss. On 1996-1997 trucks our 47RE Ram 2500 Cummins common problems guide walks through those checks, and the 47RE identification guide helps you confirm which automatic you have.
This kit is listed for 1991-1993 Dodge Ram D250/D350 and 1994-1997 Ram 2500/3500 trucks with the 5.9L 12-valve Cummins. The tank sizes differ by year: 30 gallon on 1991-1993 and 35 gallon on 1994-1997. Before you order, check the Mopar sending unit number on your old unit against the Fleece cross-reference: 52018309 (1991-1993), 4864735 (1994), 4864209 (1995) or 4798671 (1996-1997), plus the superseded numbers Fleece lists. A truck that was swapped to a gasoline-model tank will not take this kit. A 1989-1990 truck that has been swapped to a 1991-1997 tank can use it. A 1998 12-valve needs a different Fleece kit (FPE-PF-CUMM-98-12V). If you are not sure, send us your year and VIN. More parts for these trucks are in our engine and fuel parts category and on the 47RE parts page.
With the fuel side sorted, many owners add a BD pulse exhaust manifold for the 12-valve or an exhaust brake for towing. If you tow heavy with an automatic, also read our 47RE towing upgrades and consider a 47RE transmission cooler.

No. Fleece lists a separate kit, FPE-PF-CUMM-98-12V, for 1998 model year 12-valve trucks. Those trucks came with sending unit 52102079AB, which uses a different resistance range than the 1991-1997 senders.
Check the Mopar part number on your existing sending unit against the Fleece chart: 52018309, 4864735, 4864209 or 4798671, or one of their superseded numbers. If your number is not on the list, or the truck has been converted to a gasoline-model tank, it is not verified to fit.
Yes. The PowerFlo replaces the factory engine-mounted lift pump, and the kit includes the FPE-CUMM-FBOP block-off plate to seal the port on the engine.
The PowerFlo has a new integral sending unit and float, so a gauge that quit because of a worn sender should read again. It does not have provisions for the low fuel warning lamp.
Only if the truck has already been swapped to a 1991-1997 style fuel tank. Fleece states it works on 1989 and 1990 trucks with that tank swap.
