Posted August 7, 20204 yr comment_603909 @zKars Do you know if the check valves from the Nikki 510 pump are the same as the Nikki 240 pump? I noticed in the FSM that specified PSI for the L20 is different than the L16. Is it the Check Value that control that? Anyone?

August 7, 20204 yr comment_603910 Same check valves. Fuel pressure on a z is controlled by an orifice in the return line of the fuel rail. Link to comment https://www.classiczcars.com/forums/topic/64314-fuel-pump-check-valves/#findComment-603910 Share on other sites More sharing options...
