Problem: If you are running an aftermarket pump that is mounted external of the fuel tank, you will need to install a draw straw or drill your fuel tank to accommodate a sump.  Each of these has some pretty significant drawbacks including the 1/4 tank issues that result in cavitation of the pump when you draw air into the fuel system. Soluttion: SureFlo performance sending units are designed to work with aftermarket lift pumps and fits directly into your stock sending unit location. It features factory style quick disconnects to adapt your stock fuel lines at the tank, giving you the cleanest installation available, and requiring no cutting or drilling of the tank. SureFlo works by drawing fuel from, and returning fuel to, the bucket assembly at the base of the unit. This ensures you are always drawing fuel into your pump and not drawing air into the fuel system as well as eliminates the dreaded 1/4 tank problems. The SureFlo bucket also incorporates one way check valves to allow fuel to easily flow in at lower levels. Our SureFlo performance sending units are also a great alternative for trucks originally equipped without an in tank pump needing to repair a malfunctioning level sender or if you are simply looking to run your own custom fuel lines directly to the tank.  Features: OEM style fitment that requires no tank cutting or drilling New fuel level electronics and fuel float Heavy duty billet aluminum cap Universal -8 AN ports for professionally plumbing a custom fuel setup New tank flange seal Adaptation pigtail connector Application Notes: Important- Verify your existing MOPAR sending unit part number is listed in the table below. If your part number is not shown, then it is not verified to fit.  Many trucks have been retrofitted over time to gasoline model tanks and the SureFlo will not fit into a retrofitted tank configuration.   Cross-reference chart: Model Year Replaces MOPAR P/N Previously Superseded P/N's Fuel Tank Size 1991 52018309 52004838, 52004937 30 Gallon 1992 52018309 52004838, 52004937 30 Gallon 1993 52018309 52004838, 52004937 30 Gallon 1994 4864735 R4864735, 4864735 35 Gallon 1995 4864209 04798293, 52102024, 52127802, R4864209, 4864209 35 Gallon 1996 4798671 04798293, 52102024, 52127802, R4864209, 4864209 35 Gallon 1997 4798671 04798293, 52102024, 52127802, R4864209, 4864209 35 Gallon 1998 4897668AD 0489766AD, 489766AE 26, 34, 35 Gallon
