The few pump failures we've seen in the past were on cars that sat around for 6 months to a year at a time without running. In cases like these, even the fuel pump can clunk out too.
Justin, our lead tech, has been using the same WMI pump and system for the past 7 years. It's seen use on his xA with the Blitz SC, non-intercooled Greddy Turbocharger, and now the PTUNING Turbo and Built Motor (stock cylinder head) combo.
His car currently makes 350+WHP on our DD Dyno with 93 octane pump and WMI. For the first 3-4 years, he was running just -20F blue windshield washer fluid, but has recently switched over to a 50/50 custom blend.
His xA currently has 147,000+ miles on the odometer. He estimates that his WMI pump has seen over 120K of use so far. So yeah, WMI can be very reliable.
