si rail, stock injectors, stock fpr (ive also tried a b&m reglator)....when i pime the fuel system it shoots up to 40psi like it should, then begins to fall, pauses at 20 and then seems to settle at 10 psi within 30 seconds. this is after i found a leak from the #4 injector bc of a damaged 0 ring. there are no leaks to be found anywhere, car does start up and run. anyone have any ideas??


edit.....just let it run for awhile and then the p[ressure stopped dropping as fats...then went and filled the gas tank and now the pressure only drops slightly from 40 to about 36-38 psi

Theres also a check valve in the pump also that hold constant pressure on the fuel system.
