The vacuum applied should take spring pressure away and therefore lower your pressure.Ahh you are correct, got it the wrong way round. Link to comment Share on other sites More sharing options...
horze Member 35 Member For: 12y 11m 1d Posted 16/07/14 09:14 AM Author Share Posted 16/07/14 09:14 AM well the guy at ford has no idea.... 6 na and 6 turbo is a diff fuel pump.... ive got the standard fuel pump in now.. and it feels like its running better.. so cant wait to put the proper one in..... seems like alot of people use a walbro as a aftermarket pump........ should I go a delphi or walbro... is the walbro mainly for modified engines?
