Looking to get a Fuel Pressure Regulator onto an Ecotec Astra in preparation for some head and Cam work to follow.
(1) Will this cause any problem being fitted whilst other mods are not yet completed. Obviously needing to be adjusted when they are.
(2) What is meant where it says an FPR is necessary for the EFI engine. Not being sure of the EFI term, is this applicable to me or not ?
Thanks for any advice.
