g-dub 0 Posted March 20, 2005 fitted a fuel pressure guage today and am wondering what pressure in psi should it be, the guage is plummed in the pipe that runs from the fuel pump to the regulator if you haven't seen it before and plummed in it is currently sitting at 14 psi, can't imagin it's fitted wrong as its just plug between the pipe, (no electricals) Quote Share this post Link to post Share on other sites
flusted 0 Posted March 21, 2005 i think the way youve plumbed it in will only show pump pressure,not system pressure?wot are you trying to achieve? The pump can pump up to 12bar (1bar=14.75psi) k-jet systems normally run 4-5bar system pressure and digipants normally run 3-5bar Quote Share this post Link to post Share on other sites
g-dub 0 Posted March 21, 2005 i believe i have fitted it backwards now, got no destructions with it so, i'm guessing the fuel has to flow a certain way, as i squeezed the fuel pipe and the pressure went up, so probably looking at around 3-5 as you said. acheive nothing really just saw this shiny guage and had to have it, but obviously want it to work Quote Share this post Link to post Share on other sites
stevemac 0 Posted March 21, 2005 G60's use a 4bar fuel pump with either a 3bar (std) or 3.5bar (uprated) FPR. Quote Share this post Link to post Share on other sites

stevemac 0 Posted March 21, 2005 The fuel pumps get a little tired with age. G60's use the same 4bar pump as the VR6's. Most G60's will still have the original pump - 12-14 years old !! I'm fitting a new pump on mine as part of the rebuild - I'll keep the old one as a spare. If you replace the pump - be sure to get the same make as the one fitted. The Bosch pump uses a different level sender to the Pierburg one. Quote Share this post Link to post Share on other sites
Guest Posted March 21, 2005 The system pressure should always be checked off of the pressure feed line and a G60 will run 2.5 - 3.0 bar and a VR6 will run 3.5 - 4.0 bar when testing pressures. Cheers, Dennis Quote Share this post Link to post Share on other sites

Cheers, Dennis Even though they both use the same 4bar pump ? Quote Share this post Link to post Share on other sites
Supercharged 2 Posted March 22, 2005 The early G60's used the lift pump with external pump under car setup... Quote Share this post Link to post Share on other sites
