Frequently Asked Questions
How do I size the 88-99 Chevrolet C/K 1500/2500 Truck 200 Fuel Pump & Hanger for my engine?
Use target power, fuel type, base pressure, boost pressure, voltage at the pump, and expected duty cycle. Follow Aeromotive's current flow data for this exact model and include a safe capacity reserve.
Can this pump be used with E85, methanol, or diesel?
Fuel compatibility is model specific. Use only the fuels Aeromotive lists for this exact part number; do not infer compatibility from another pump in the same series.
Does this pump require a return-style fuel system?
That depends on the pump, regulator, controller, and vehicle strategy. Confirm the complete system design rather than selecting the pump by flow rating alone.
What wiring is required for this pump?
Size wire, fuse, relay or controller, grounds, and connectors for the manufacturer's current draw and voltage requirements. Voltage drop directly reduces pump performance.
Should a pre-filter and post-filter be used?
Use the filtration layout and micron ratings Aeromotive specifies for this exact pump and fuel. Incorrect filtration can restrict flow or damage the pump and injectors.
Installation Instructions
- Confirm Aeromotive part number 18378, the complete system design, fuel or fluid type, and all required supporting components.
- Relieve system pressure, disconnect electrical power, work in a ventilated area, and eliminate ignition sources before opening any fuel connection.
- Install with the exact port sizes, seals, mounting orientation, line support, filtration, wiring, and torque values in Aeromotive's current instructions.
- Prime and pressure-test the complete system; inspect every joint, seal, vent, and electrical connection for leaks, heat, abrasion, and voltage drop.
- Verify stable pressure and safe operation under load, then recheck fittings and mounting after the initial heat cycles.
Aeromotive
Aeromotive fuel-system components support properly engineered street, competition, powersports, and custom vehicle applications. Shop fuel pumps, pressure regulators, filters, tanks, rails, fittings, wiring, controllers, and service parts by exact manufacturer part number and verified system requirements. Choose by System Requirements Start with target power, fuel type, base pressure, boost pressure, required flow at operating pressure, system voltage, and expected duty cycle. Then verify whether the vehicle uses an EFI or carbureted system, return or returnless plumbing, in-tank or external mounting, and the correct filtration strategy. Do not size a pump from a free-flow rating or horsepower label alone. Fuel Pumps and Controllers Aeromotive offers in-tank, external, mechanical, brushless, and spur-gear pump configurations. Confirm the pump's current flow data at the pressure your engine will actually use. Plan wire gauge, fuse, relay or controller, grounds, filters, line sizes, t...
