Aeromotive Pump Speed ControllerFor any pump, on any type of vehicle, the Aeromotive Fuel Pump Speed Controller (FPSC) minimizes fuel heating and vapor lock problems by matching the duty cycle of the fuel pump to engine RPM. At low demand, the FPSC slows the fuel pump down, reducing the chance of suction side cavitation and vapor lock. When demand increases, the FPSC returns the fuel pump to 100% duty cycle for maximum flow. It? s like an automatic transmission for your fuel pump.

Cheap-poorly made junk
Color: Coffee, Size: XX-Large
I needed a vest with some fringe for a costume party on 11/24/23. I looked at many others but decided on this one due to the fact it would arrive on Wednesday instead of Friday, the day of the party. I beyond disappointed in the quality and fit of this vest. I knew that it was faux leather but it was the worst faux leather type material I had ever seen. The fit was terrible, said 2xl but 1xl tops. It was probably my worst purchase ever on Amazon. Save your money and do not purchase this vest.

Nice!
Color: Brown, Size: XX-Large
A lot better made than I anticipated. Looks and feels like suede. For my needs, it was perfect for a costume. Fits well, and looks more expensive.
