The DeLorean Industries Modern Fuel Pump System (Gen 4) is a direct replacement for the failure-prone factory fuel pump and sender configuration. It is built around a high-quality Delphi pump unit that meets the strict reliability standards OEM manufacturers demand, and was originally released in 2010 alongside our SPEC EFI fuel-injection solutions to combat ethanol-blended fuel.
Why the factory setup fails
The factory fuel pump and sender configuration used several dissimilar materials that react poorly with modern gasoline as they age. Combined with a heat-soak condition systematic to the car’s design, the system takes a heavy beating in use — and even short periods of sitting degrade the rubber components in the tank. The sending unit was prone to varnish causing a sticking condition, internal wiring faults, and poor placement with no dedicated baffle for gauge slosh. Both components relied on open-air Lucas connectors that invited corrosion.
What the Gen 4 system changes
- Premium, fully programmable sending-unit controller with mounting system
- Premium Delphi FG 0089 pump and sender unit
- Weather Pack premium connection points — removes the failure-prone factory Lucas pins
- All-new components — no cores required
- Backed by an industry-leading warranty and support from pump manufacturer Delphi
For a time the market relied on stop-gap options, including fuel-resistant tank materials. As the supply of quality German-made Bosch pumps dwindled, a rethink became critical — aftermarket direct-fit pumps showed a 60%+ failure rate, many failing right out of the box. That drove a complete redesign and our all-in-one system, first implemented in 2010 for EFI-updated cars and quickly extended to all DMC-12 models.
