Walbro Universal 535lph In-Tank Fuel Pump E85 Version - F90000295

The biggest in-tank pump Walbro builds, priced to move. 535 lph at 40 psi, E85-validated, good for 900+ hp — the same DCSS 39/50 pump as the Hellcat unit, minus the outlet check valve, which is exactly what you want for a race car building oil pressure before start or a lift pump feeding a surge tank.

Genuine Walbro/TI Automotive through authorized distribution. The counterfeit rate on these is high enough that the cheap ones online are a real gamble — this isn't one of those.
