Delphi holds more than 30 OE proprietary innovations and 150 patents in fuel module and pump design. All pumps are tested for durability up to 150,000 miles. Delphi OE engineering and testing processes enable them to create smart, durable, electric fuel pumps with features that resist failure.
Why Do Fuel Pumps Fail?
Fuel pumps typically operate for seven to ten years before failure. Premature failures are most commonly caused by one of the following reasons:
Excessive Hot/Cold Environments
Excessively running a vehicle on a near empty tank which prevents the pump from being fully submerged causing it to overheat
The Delphi Difference
Designed and tested to operate even with low voltage to ensure a vehicle will start if it has a low battery
Rigorous OE-testing ensures the pump can withstand extreme temperatures ranging from -25 to 150F
Designed for flawless electrical installation with increased terminal size and enhanced connectors. Elimates excessive electrical resistance, improves heat dissipation, and boosts current flow capacity
Improved tubing design to reduce transmitted noise from the pump
Tested performance in corrosive, contaminated E22 and E95 fuel blends to ensure long life
Patented Generation IV turbine pump to deliver fast fuel pressure rise for fast engine starts
Pump or Assembly?
Purchasing a standalone pump is less expensive upfront but assemblies provide many added benefits:
The pump assembly contains a strainer which is required to validate the warranty
The assembly includes a fuel sender & float ensuring accurate fuel readings for the vehicle
New hoses, valves, connectors and other components are included to extend service life
Since you don't have to disassemble the housing, which could lead to damage, replacement becomes a simple swap dramatically reducing installation time
Fuel Pump Failure: Is the Pump the Problem?
Fuel Pump Replacement: Do it right the first time!
Prior to Replacing Pump, check:
Fuel Pump Fuse(s)
Fuel Pump Relay
Voltage at the Pump - test for bad wiring
Voltage drop test - corroded connector, bad wiring
Fuel System Pressure - test for pump pressure being outside accepted range
When Replacing Pump, also:
Replace the Fuel Filter
Replace the Fuel Strainer
Clean / Flush Tank
Refill with fresh, uncontaminated fuel
Fuel Pump and Strainer Set, Tank Seals, Tube, Clamps, Instruction Sheet
