Product Description

The Aeromotive 18399 Dual 340 LPH In-Tank Fuel Pump is a high-performance upgrade designed specifically for 1988-1997 Chevrolet and GMC C/K 1500/2500 V8 pickup trucks. This direct drop-in assembly replaces the stock fuel delivery module with two high-flow Stealth pumps that significantly increase fuel supply capacity for EFI, forced-induction, and high-horsepower builds. Its dual pump configuration supports up to approximately 1400 rear-wheel horsepower on gasoline and roughly 980 rear-wheel horsepower on E85 when implemented in appropriately tuned engines.

Each pump includes a 100-micron pre-filter to guard against debris and ensure long life, while individual wiring terminals allow staged control or simultaneous operation depending on system design. A single -08 ORB outlet port with included -08 swivel fittings streamlines fuel plumbing, and a calibrated 0-90 Ohm level sender maintains gauge functionality. This assembly is engineered to be a **direct tank drop-in** with no drilling required in compatible stock GM fuel tanks, making installation much easier for performance conversions and upgrades.

Ideal for street, strip, or performance truck builds where consistent high-flow fuel delivery is essential, the 18399 helps eliminate fuel starvation and supports aggressive power goals. Always verify your configuration's tank style and clearance before installation, and pair with a quality fuel pressure regulator and plumbing to complete a reliable high-flow system. This part is intended for performance applications and **is not legal for sale or use on emission-controlled vehicles** except as a direct replacement matching OEM specifications.
