E7 427 fuel pump leaks


Recommended Posts

There is an updated delts seal kit for the unit pumps. Also the bolts must be tightned down evenly or the o-rings will get cut or nicked. Make sure the bores are clean and smooth. Always use new unit pump bolts with a little oil on the threads and torque to 60 ft lbs. Also make sure it is not leaking between the solenoid and the body of the unit pump. If it is there is a seal kit for that but it takes a special torks plus bit to remove the screws.
