Edit I notice plaz only sells the 535 / F90000295 without the check valve, no good for standard application, correct?

Typically not an empty surge. This caters for 99% of all applications... a full race circuit car is a different story and would benefit from as big of a lift pump as you can get 1 Link to comment Share on other sites More sharing options...
