tyson Posted August 25, 2012 Share Posted August 25, 2012 Hey guys, 240Z Turbo, aftermarket fuel rail, 440cc injectors that were just professionally tested and not leaking, It's got an aftermarket fuel sump/pump (not sure what brand/model). When I pressurize the system it's at 38PSI, and holds there for as long as I can bear to look at it. After an hour or two, it's dropped down to ~15PSI and then eventually to zero. Car starts and runs fine. Is it anything worth looking into? Thanks - Tyson Quote Link to comment Share on other sites More sharing options...
johnc Posted August 25, 2012 Share Posted August 25, 2012 Pressure bleed back through the fuel pump. Nothing to worry about. Quote Link to comment Share on other sites More sharing options...
tyson Posted August 25, 2012 Author Share Posted August 25, 2012 Didn't think so, just wanted to make sure it wasn't an early sign of something going bad. Thanks! Quote Link to comment Share on other sites More sharing options...
