12 Bolt EFI to Aeromotive 10 Bolt Stealth Adapter Plate

$58.00

Adapter plate that mounts a 10-bolt Aeromotive Stealth fuel pump to a 12-bolt Boyd tank. CNC 6061-T6, stainless screws included. Adds 0.625 in., so check hanger depth.

  • Ethanol-safe seal - the Viton gasket handles pump gas and ethanol blends without going soft.
  • Machined, not cast - CNC-cut so the 3.510 in. bore and both bolt circles land exactly.

Install Level: Moderate

Fits Aeromotive Phantom 340, A1000 and Eliminator 10-bolt pumps. Not the Trifekta 18311.
Pump not included. Reuse your pump's gasket and nylon washers, not its screws.
Lead time: 2 weeks.
