Hello there. I got a mech to fit a new pump on hino 700, e13C engine but it's now pumping diesel into the oil sump. Everything seems to be working well and excess fuel is returning to the tank. However there seems to be too much pressure in the return pipe. If I rave I saw diesel splashing from the pump. Can someone help on the cause. Could it be wrong timing of injector pump.
