Hitachi HPFP

[guile]

FYI HPA also hand build and test HPFP before they distribute them...

https://www.hpamotorsports.com/product_hpfp.html

"HPA addresses the fueling limitations of the FSI with a hand assembled, bored and oversized, High Pressure Fuel Pump that delivers a 40% increase in fuel volume over stock. HPA's oversized piston is manufactured from H13 tool steel and all surfaces are nitride treated before assembly.

Individually tested and serialized, HPA customers will enjoy a 5 year warranty against manufacturing defects. Only the highest manufacturing standards are applied and each pump is assembled in a controlled environment to ensure against debris and material contamination.

HPA only uses NEW OEM pumps as cores, no remanufactured or rebuilt pumps."
