Edit I notice plaz only sells the 535 / F90000295 without the check valve, no good for standard application, correct? Edited 01/06/20 02:56 AM by camo86T

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

This is all you need for e85 lift pump. https://www.tiperformance.com.au/products/walbro-250lph-fuel-pump-kit-e85-f10000302/
