1、通电型断油阀发动机燃油系统的排气程序接上起动蓄电池将控制屏内标有“FCR”的中间继电器上的按钮轻轻拔出来拧松放气螺钉（1）用手动输油泵（2）泵油，直到流出的燃油不含气泡为止，在燃油继续流出的同时拧紧排气螺钉（1）继续泵油15-20次，检查是否有泄漏重要！将控制屏内“FCR”中间继电器的按钮压下复位喷油泵手动输油泵放气螺钉注意：对装有断油阀的发动机喷油泵也需要经常排气，这可由拧松喷油泵压力均衡器（27mm开口扳手）来实现，用手动输油泵泵油直到流出的燃油不含气泡为止。Vent procedure for fuel system on Energize To Run(E.T.R.) enginesC
2、onnect batteryPull up the blue test button on the intermediate relay “FCR” in control panelLoose vent stud（1）Hand pump(2) fuel until there is no bubble appears in outflowing fuel,and then tight the vent stud（1） while fuel is spill outHand pump fuel for 15-20 times more and check for leakageIMPORTANT
3、: Press down the blue test button on the intermediate relay “FCR” in control panel to reset1. Vent stud2. Hand pump3. Injection pumpNOTE：Injection pump venting is also needed on E.T.R. engines.This can be accomplished by loose the pressure balancer(27mm wrench)and then Hand pump(2) fuel until there is no bubble appears in spill fuel.
