The Driven Diesel DD-73FS-VAN-RRK-V2 is a custom regulated return fuel system engineered specifically for 1999–2003 7.3 Powerstroke E-Series vans. It retains the factory engine valley fuel filter bowl while eliminating the restrictive factory "dead-headed" fuel rail configuration. Driven Diesel packages this second-generation system with custom pre-bent rigid stainless steel lines tailored for cramped van engine bays, high-temp Teflon braided stainless return lines, a custom stainless mounting bracket, a premium Fuelab adjustable bypass fuel pressure regulator, and a liquid-filled fuel pressure gauge.

Injector cackle, aeration wear on fuel injectors, fuel pressure starvation under load, and noisy engine idle in tightly packaged van cowls are what this kit solves. By feeding diesel fuel to both ends of each cylinder head and returning excess fuel through the Fuelab bypass regulator, trapped air and aerated fuel are directed back to the tank instead of being forced into the injector barrels. Because van doghouse clearances and firewall contours are vastly different from Super Duty pickups, standard truck regulated return kits will not fit; this V2 system is purpose-bent exclusively for E-Series architecture. It is the van regulated return plumbing and regulator kit only; fuel pumps, filters, and lines from the tank to the bowl are sold separately.

It fits 1999–2003 7.3 Powerstroke Ford E-Series vans equipped with the factory fuel filter bowl and stock or drop-in turbochargers.

Remove the van interior doghouse cover and disconnect both negative battery cables before beginning installation. Drain the factory fuel filter bowl completely using the drain valve to avoid spilling diesel into the valley. Hand-thread all stainless line fittings loosely onto the cylinder head ports and regulator block to verify clearance against the firewall, intake, and high-pressure oil lines before tightening any fitting to final torque. Cycle the ignition key several times to purge air from the system, set the Fuelab regulator set screw to 60–65 PSI on the gauge, and inspect all connections thoroughly for leaks before reinstalling the interior doghouse.
