Product Description
Part Number 11191: This brushless in-line 3.5 spur gear pump comes with a variable speed pump controller. It offers Pro-Series performance and more. For fuel injected engines, it can handle up to 2400 FWHP for naturally aspirated and up to 1800 FWHP for forced air induction. For carbureted engines, it supports up to 2600 FWHP for naturally aspirated and up to 2000 FWHP for forced air induction. It's E85 compatible, but you need to reduce the max FWHP by 30%. It's lighter than the traditional Pro-Series pump, draws less current at higher EFI pressures, and has an extended service life in methanol and ethanol. It features a new integral spur-gear pumping mechanism, can operate at 90-PSI continuously and reach up to 150-PSI peak pressure (base plus boost). It has an integral, external brushless controller for a clean installation, cooler fuel, and enhanced reliability. The ports are ORB-12 inlet and ORB-10 outlet. It requires a straight 12-VDC to 16-VDC power supply and is not compatible with pulse modulated systems or fuel pump speed controllers. The EFI rated flow is 1,250 lbs./hr. @ 40 psi, 13.5 volts, and the carb rated flow is 1,350 lbs./hr. @ 9 psi, 13.5 volts. Aeromotive’s True Variable Speed Controller offers built-in pump speed control via a dedicated 0-5V analog DC input signal. It reduces fuel flow during low engine demand and decreases current draw, minimizing motor heat and environmental impact through reduced fuel recycling.
Using this Aeromotive fuel pump is straightforward. First, make sure you have a straight 12 - 16 VDC power supply as it's required for the pump to work. Connect it to your engine system, using the ORB - 12 inlet and ORB - 10 outlet ports. When using with an E85 fuel, remember to reduce the max FWHP by 30%. This pump isn't compatible with pulse modulated systems or fuel pump speed controllers, so avoid connecting it to such systems. For maintenance, keep an eye on the current draw and the operating pressure. If you notice any abnormal changes, it might be a sign that something needs checking. In methanol and ethanol, this pump has an extended service life, but still, it's a good idea to inspect it regularly. Also, since the True Variable Speed Controller reduces fuel flow during low engine demand, it helps save energy and reduces motor heat, so don't mess with the controller settings unless you really know what you're doing.
