Walbro 190HP Fuel Pump - 60 Miles of use
Installed for 3 days on my 2002 Miata, maybe 60 miles on it and I have the receipt from a couple of weeks ago. I was having an issue with the car leaning out at the top of my RPM range so BEGi recommended this. I threw it in and still had the same problem. Turns out I was just maxing out my MAF sensor 
$70 Shipped
This is the High Pressure 190LPH pump. This is otherwise known as the best pump for 99% of modified Miata's out there.

"Regardless, there are still a few options in fuel pumps. The ideal pump is the Walbro 190 lb/h HP fuel pump. HP stands for high pressure. It is important you get a HP unit if you plan on raising the fuel pressure levels past 90psi. The HP models can supply fuel up to 130psi. The standard 190 lb/h fuel pump is maxed at 90psi and the standard 255 lb/h pump is maxed at 80psi. The 190 HP unit will not only supply four 700cc injectors with enough flow to maintain 40-50psi in the fuel rail (enough for 400hp), but out flows the 255 HP model after 100psi.
It is recommended for most applications to go with the 190LPH, 190HP if using a FMU."
