Hi. Is it possible for a pressure decay device make a minus value in leak test? I checkd some plastic fuel rails with 50 cm hose assembled on them. just one of them had a 10 cm hose but the volume, on the device, was set for 50s. the leakage was showd the same magnitude but minus for the part with smal hose.
Is there anybody can explain how?
I also cuted another hose and the minus result was repeated for this new one. Also performed the test by clamping device output pipe to be sure about internal leakage of the device. but this time it rises a plus valu!
