SimonB Posted January 22, 2005 Share Posted January 22, 2005 Just done a search to find out what the stock static fuel pressure is. Only thing is, there are several posts on here saying it's 36psi, and several on Supraforums saying it's 43psi. Would it really be different on US cars, or is one of these figures wrong? Is there a definitive figure somewhere from a service manual or something? Link to comment Share on other sites More sharing options...
Terminator Posted January 22, 2005 Share Posted January 22, 2005 Taken from my toyota manual. Fuel pressure with vac hose to FPR disconnected = 40psi at idle. with hose connected = 31 psi at idle. After switch off it should not drop below 21psi for five minutes. Link to comment Share on other sites More sharing options...
SimonB Posted January 23, 2005 Author Share Posted January 23, 2005 Thanks for that. I presume that's from the UK service manual? I wonder if there would be a difference between Jspec and UK fuel pressures? Has anyone with a fuel pressure gauge measured what the pressure is with the vac hose disconnected from the FPR?

Yes its from a 1993 Repair manual. Pub.No. RM354E You might try the NZ guys theur site has loads of FAQ's and they only have JDM cars. Link to comment Share on other sites More sharing options...
